Report on Form 10-K for the fiscal year ended December 31, 2018.

2019 Executive Overview

Schlumberger full-year 2019 revenue of $32.9 billion was essentially flat with 2018. International revenue, however, grew in the high single-digits as anticipated.



In the oil markets, sentiment was stable and positive for the first four months
of 2019, with the Brent oil price moving from $55 per barrel at the beginning of
the year to a high of $75 per barrel in late April. OECD crude and product
stocks continued to increase through much of 2019, reversing a trend that
persisted throughout the first half of 2018. Internationally, activity and
investment continued to strengthen, particularly offshore.

Activity in North America land was strong in the first half of 2019 but slowed
in the second half of the year as a combination of budget exhaustion and cash
flow constraints impacted our customers. Although the slowing activity in the
second half of the year was consistent with the trend experienced in 2018,
activity dropped earlier and steeper in the second half of 2019 as compared to
the previous year.

By midyear, concerns of a recession in the United States and indications of well
supplied global oil markets pushed the oil price to its low point for the year.
These concerns abated over the latter part of the year as oil demand indicators
trended positively. Though trade conflicts persisted, they did not create a
significant drag on oil markets for the balance of the year.

The attacks on Saudi Arabia oil infrastructure in September 2019 caused a price
increase of only $7 per barrel, and the price of Brent crude retreated to
pre-attack levels over the course of the following week, demonstrating that the
markets were well supplied. In December 2019, OPEC+ agreed to further production
cuts in 2020 to alleviate the projected oversupply.

Global natural gas pricing was consistent with well-supplied markets during
2019. Liquified natural gas (LNG) supply capacity increased by an estimated 10%
during 2019, and consequently LNG prices in Asia and Europe were less than half
the prices seen in 2018.

Domestically, US Henry Hub natural gas prices showed continued weakness during
2019 as North American gas production increased. Prices averaged $2.56 per
million British thermal units ("mmbtu") for the year, with the peak of $4.25 per
mmbtu occurring in March. The price fell to its lowest point of $1.75 per mmbtu
in December.

Schlumberger financial performance in 2019 was primarily driven by the
international markets. Full-year 2019 international revenue of $21.8 billion
increased 7% over 2018, again outpacing North America revenue and continuing a
trend which began in the third quarter of 2018. This strong international
performance was the result of increased activity on the part of operators, as
they continued to invest in longer-term resource development following a
sustained period of underinvestment and declining production.

In contrast, after two years of strong growth, North American revenue fell
sharply by 10% to $10.8 billion.  This decrease was largely driven by the land
market weakness affecting the OneStim pressure pumping business, as customers
reached their budget limits earlier in the year and remained highly disciplined
on capital spend.

Additionally, during the fourth quarter of 2019, Schlumberger completed two major milestones: the formation of the Sensia joint venture and the divestiture of the Drilling Tools business. Together these two transactions resulted in Schlumberger receiving net cash proceeds of $586 million.



From a macro perspective, the year ended with sentiment regarding 2020 oil
demand growth turning positive as uncertainty reduced following the progress
made toward a US-China trade deal. The fall in the North America production
growth estimate of between 400,000 to 800,000 barrels-per-day should continue to
support the thesis for international investment. The recent escalation of
geopolitical risk should set the floor for the oil price going forward. In the
near term, Schlumberger expects the OPEC+ production cuts agreed upon in
December 2019 to limit investment and activity, particularly in the Middle East
and Russia, during the first half of 2020. As the year progresses, the effect of
slowing North America production growth is likely to cause tightness in the
market and further stimulate international operators to increase their
investments in the second half of the year and beyond.

                                       13



--------------------------------------------------------------------------------


Based on these factors, the expectation is for the 2020 exploration and
production capex spending growth rate in the international markets to be in the
mid-single-digit range. Schlumberger therefore expects its international
portfolio revenue to grow at the same pace or higher, excluding the effects of
the businesses transferred to the Sensia joint venture and the businesses
divested in the Drilling Tools transaction. The businesses included in these
transactions accounted for approximately 2% of Schlumberger's global revenue in
2019. International revenue growth will be more heavily weighted to the second
half of the year with increasing offshore activity, improving activity mix from
the early deepwater growth cycle, and increasing exploration work toward the end
of the year and into 2021.

In North America, Schlumberger is continuing to scale-to-fit its organization
and portfolio by repurposing or exiting underperforming business units, focusing
on asset-light operations, and expanding its technology access business models.
Schlumberger is cautiously optimistic that the high-grading of its portfolio
will promote margin expansion and the improvement of returns in the North
America land market.

Fourth quarter revenue of $8.2 billion was 4% lower sequentially. International
revenue of $5.7 billion grew 2% sequentially. However, North America revenue of
$2.5 billion dropped 14% sequentially due to customer budget exhaustion and cash
flow constraints.

Sequential international growth was led by the Middle East & Asia area, where revenue increased 5%. Latin America revenue grew 1%, while revenue in the Europe/CIS/Africa area only declined 2% given the mild winter slowdown of activity in the Northern Hemisphere.



The fourth quarter of 2019 delivered the first sequential growth in
international margin in any fourth quarter since 2014. Schlumberger is therefore
confident that it has turned the corner, particularly as it has experienced
sequential international margin growth in each of the last three quarters.
Meanwhile in North America land, margin compression from lower activity was
minimized by implementing a scale-to-fit strategy, acting decisively in reducing
capacity, and restructuring operations to protect margins.

                                       14

--------------------------------------------------------------------------------

Reservoir Characterization



Fourth-quarter revenue of $1.6 billion decreased 1% sequentially following the
end of the summer campaigns for Wireline and Testing activity in the North Sea
and Russia, where the mild winter did not significantly disrupt activity.

Reservoir Characterization pretax operating margin of 22% increased 59 basis points ("bps") sequentially primarily driven by increased high-margin SIS digital software sales.

Drilling



Fourth-quarter revenue of $2.4 billion decreased 1% sequentially primarily due
to the end of the summer drilling campaign in Russia and lower drilling activity
in North America land.

Drilling pretax operating margin of 12% was flat sequentially as margin improvements from drilling projects in the Middle East were offset by the seasonally lower margins in Russia and lower drilling margins in North America land.



Production

Fourth-quarter revenue of $2.9 billion declined 9% sequentially driven by lower
activity and pricing for OneStim in North America land due to expected customer
budget limitations and cash flow constraints.  Schlumberger continued to
right-size its hydraulic fracturing capacity by stacking more fleets in light of
lower demand.

Production pretax operating margin of 9% contracted by 32 bps sequentially due
to the lower OneStim activity, partially offset by strength in international
margins from higher activity.

Cameron



Fourth-quarter revenue of $1.4 billion increased 2% sequentially from higher
OneSubsea, Surface Systems, and Drilling Systems revenue primarily in the
international markets. Valves & Process Systems was lower sequentially due to
the reduced North America land activity and as a result of contributing the
Valves & Process Systems measurement business to the Sensia joint venture, which
closed on October 1,  2019.

Cameron pretax operating margin of 9% contracted by 359 bps sequentially, driven largely by reduced margins in the OneSubsea project portfolio.

                                       15



--------------------------------------------------------------------------------
Full-year 2019 revenue of $32.9 billion was essentially flat year-on-year with
North America revenue decreasing 10% and international revenue increasing 7%.
The international results were underpinned by increased investment levels. In
contrast, the North America results reflect a slowing production growth rate on
land as operators maintained capital discipline and reduced drilling and
hydraulic fracturing activity.

Reservoir Characterization

Full-year 2019 revenue of $6.3 billion increased 2% year-on-year primarily driven by increased international activity.

Year-on-year, pretax operating margin decreased 79 bps to 21%.

Drilling



Full-year 2019 revenue of $9.7 billion increased 5% year-on-year primarily due
to higher demand for drilling services, largely in the international markets
that benefited Drilling & Measurements, M-I SWACO, and Integrated Drilling
Services.

Year-on-year, pretax operating margin decreased 89 bps to 13% despite higher revenue as margins were affected by competitive pricing and higher costs associated with a number of integrated contracts internationally.

Production



Full-year 2019 revenue of $12.0 billion decreased 3% year-on-year with most of
the revenue decline attributable to lower OneStim activity in North America as
customers reduced spending due to higher cost of capital, lower borrowing
capacity and expectation of better returns from their shareholders.

Year-on-year, pretax operating margin decreased 20 bps to 8% primarily due to reduced profitability in OneStim in North America.

Cameron

Full-year 2019 revenue of $5.3 billion decreased 3% year-on-year due to lower revenue for OneSubsea and Valves & Process Systems.

Year-on-year, pretax operating margin decreased 35 bps to 11%.

Interest and Other Income

Interest & other income consisted of the following:





                                 (Stated in millions)

                                      2019      2018
Interest income                       $  41     $  60

Earnings of equity method investments 45 89

$  86     $ 149

The decrease in interest income in 2019 compared to 2018 is primarily attributable to lower cash and short-term investment balances.

The decrease in earnings from equity income is associated with Schlumberger's equity investments in rig-and seismic-related businesses.

Interest Expense

Interest expense of $609 million in 2019 increased $34 million compared to 2018. This increase is primarily due to an increase in the weighted average debt balance during 2019 as compared to 2018.

Other

Research & engineering and General & administrative expenses, as a percentage of Revenue, were as follows:





                         2019      2018
Research & engineering     2.2 %     2.1 %
General & administrative   1.4 %     1.4 %


                                       16



--------------------------------------------------------------------------------

Income Taxes

The Schlumberger effective tax rate is sensitive to the geographic mix of earnings. When the percentage of pretax earnings generated outside of North America increases, the Schlumberger effective tax rate generally decreases. Conversely, when the percentage of pretax earnings generated outside of North America decreases, the Schlumberger effective tax rate generally increases.

The Schlumberger effective tax rate was 3% in 2019 as compared to 17% in 2018. The lower effective tax rate was almost entirely due to the charges and credits described in Note 3 to the Consolidated Financial Statements, which primarily related to non-deductible goodwill.

Charges and Credits

Schlumberger recorded significant charges and credits during 2019 and 2018. These charges and credits, which are summarized below, are more fully described in Note 3 to the Consolidated Financial Statements.



The following is a summary of the 2019 charges and credits, of which the $247
million gain on the formation of the Sensia joint venture is classified in Gain

A significant portion of the third-quarter impairment charges were recorded
effective August 31, 2019. Accordingly, the 2019 results reflect a $108 million
reduction in depreciation and amortization expense for the last four months of
2019. Approximately $84 million of this amount relates to the Production
segment. The remaining $24 million is reflected in the "Corporate & other" line
item.

The following is a summary of the 2018 charges and credits, of which the $215
million gain on the sale of the marine seismic acquisition business is
classified in Gain on sale of business in the Consolidated Statement of Income

(1) "Net Debt" represents gross debt less cash, short-term investments and fixed

income investments, held to maturity. Management believes that Net Debt

provides useful information regarding the level of Schlumberger's

indebtedness by reflecting cash and investments that could be used to repay

debt. Net Debt is a non-GAAP financial measure that should be considered in

addition to, not as a substitute for or superior to, total debt.

(2) Includes depreciation of property, plant and equipment and amortization of

intangible assets, multiclient seismic data costs and APS investments.

(3) Includes severance payments of approximately $128 million during 2019 and

$340 million during 2018.

(4) "Free cash flow" represents cash flow from operations less capital

expenditures, APS investments and multiclient seismic data costs capitalized.

Management believes that free cash flow is an important liquidity measure for

the Company and that it is useful to investors and management as a measure of

the ability of our business to generate cash. Once business needs and

obligations are met, this cash can be used to reinvest in the company for

future growth or to return to shareholders through dividend payments or share

repurchases. Free cash flow does not represent the residual cash flow

available for discretionary expenditures. Free cash flow is a non-GAAP

financial measure that should be considered in addition to, not as substitute


    for or superior to, cash flow from operations.



Key liquidity events during 2019 and 2018 included:

• Cash flow from operations was $5.4 billion in 2019 and $5.7 billion in 2018.

• On January 21, 2016, the Board approved a $10 billion share repurchase

program for Schlumberger common stock. Schlumberger had repurchased $1.0

billion of Schlumberger common stock under this program as of December 31,

2019.

The following table summarizes the activity under this share repurchase program during 2019 and 2018:

  • Dividends paid during each of 2019 and 2018 were $2.8 billion.


• Capital expenditures were $1.7 billion in 2019 and $2.2 billion in 2018.

Capital expenditures during 2020 are expected to be similar to that of 2019.

• During the fourth quarter of 2019, Schlumberger repurchased the remaining

$416 million of its 3.00% Senior Notes due 2020; $126 million of its 4.50%

Senior Notes due 2021; $500 million of its 4.20% Senior Notes due 2021; and

$106 million of its 3.60% Senior Notes due 2022.

• During the fourth quarter of 2019, Schlumberger completed the sale of the

businesses and associated assets of DRILCO, Thomas Tools and Fishing and

Remedial Services and received net cash proceeds of $348 million. These

businesses represented less than 1% of Schlumberger's consolidated 2019

revenue.

• During the fourth quarter of 2019, Schlumberger and Rockwell Automation

closed Sensia, their previously announced joint venture. Rockwell Automation

owns 53% of the joint venture and Schlumberger owns 47%. At closing,

Rockwell Automation made a $238 million cash payment, net of working capital

adjustments, to Schlumberger.

• During the third quarter of 2019, Schlumberger issued €500 million of 0.00%

Notes due 2024, €500 million of 0.25% Notes due 2027 and €500 million of

0.50% Notes due 2031.

• During the third quarter of 2019, Schlumberger repurchased $783 million of

its 3.00% Senior Notes due 2020 and $321 million of its 3.625% Senior Notes

due 2022.

• During the second quarter of 2019, Schlumberger completed a debt exchange

offer, pursuant to which it issued $1.500 billion in principal of 3.90%

Senior Notes due 2028 in exchange for $401 million of 3.00% Senior Notes due

2020, $234 million of 3.63% Senior Notes due 2022 and $817 million of 4.00%

Senior Notes due 2025.

Senior Notes due 2024 and $850 million of 4.30% Senior Notes due 2029.

• During the fourth quarter of 2018, Schlumberger issued €600 million of 1.00%


      Guaranteed Notes due 2026.


                                       19


--------------------------------------------------------------------------------

• During the fourth quarter of 2018, Schlumberger completed the divestiture of

its marine seismic acquisition business for net proceeds of $579 million

(after considering $21 million of cash divested).

• During 2019 and 2018, Schlumberger made contributions of $25 million and $83

million, respectively, to its postretirement benefit plans. The US pension


      plans were 92% funded at December 31, 2019 and 88% funded at December 31,
      2018 based on their projected benefit obligations.


Schlumberger's international defined benefit pension plans were a combined 97%
funded at both December 31, 2019 and December 31, 2018 based on their projected
benefit obligations.

Schlumberger expects to contribute approximately $20 million to its postretirement benefit plans in 2020, subject to market and business conditions.



As of December 31, 2019, Schlumberger had $2.2 billion of cash and short-term
investments on hand. Schlumberger also has separate committed credit facility
agreements aggregating $6.5 billion with commercial banks, of which $4.3 billion
was available and unused as of December 31, 2019. The $6.5 billion of committed
credit facility agreements support commercial paper programs. Schlumberger
believes these amounts are sufficient to meet future business requirements for
at least the next 12 months.

The total outstanding commercial paper borrowings were $2.2 billion as of December 31, 2019 and $2.4 billion as of December 31, 2018.

average interest rate of 2.3% as of December 31, 2019.

(3) Represents an estimate of contractual obligations in the ordinary course of

business. Although these contractual obligations are considered enforceable

and legally binding, the terms generally allow Schlumberger the option to

reschedule and adjust its requirements based on business needs prior to the

delivery of goods.




Refer to Note 17, Pension and Other Benefit Plans, of the Consolidated Financial
Statements for details regarding Schlumberger's pension and other postretirement
benefit obligations.

As discussed in Note 13, Income Taxes, of the Consolidated Financial Statements,
included in the Schlumberger Consolidated Balance Sheet at December 31, 2019 is
approximately $1.3 billion of liabilities associated with uncertain tax
positions in the over 100 tax jurisdictions in which Schlumberger conducts
business. Due to the uncertain and complex application of tax regulations,
combined with the difficulty in predicting when tax audits throughout the world
may be concluded, Schlumberger cannot make reliable estimates of the timing of
cash outflows relating to these liabilities.

Schlumberger has outstanding letters of credit/guarantees that relate to
business performance bonds, custom/excise tax commitments, facility lease/rental
obligations, etc. These were entered into in the ordinary course of business and
are customary practices in the various countries where Schlumberger operates.

--------------------------------------------------------------------------------

Critical Accounting Policies and Estimates



The preparation of financial statements and related disclosures in conformity
with accounting principles generally accepted in the United States requires
Schlumberger to make estimates and assumptions that affect the reported amounts
of assets and liabilities, the disclosure of contingent liabilities and the
reported amounts of revenue and expenses. The following accounting policies
involve "critical accounting estimates" because they are particularly dependent
on estimates and assumptions made by Schlumberger about matters that are
inherently uncertain.

Schlumberger bases its estimates on historical experience and on various
assumptions that are believed to be reasonable under the circumstances, the
results of which form the basis for making judgments about the carrying values
of assets and liabilities that are not readily apparent from other sources.
Actual results may differ from these estimates under different assumptions or
conditions.

Allowance for Doubtful Accounts



Schlumberger maintains an allowance for doubtful accounts in order to record
accounts receivable at their net realizable value.  Judgment is involved in
recording and making adjustments to this reserve.  Allowances have been recorded
for receivables believed to be uncollectible, including amounts for the
resolution of potential credit and other collection issues such as disputed
invoices.  Adjustments to the allowance may be required in future periods
depending on how such potential issues are resolved, or if the financial
condition of Schlumberger's customers were to deteriorate resulting in an
impairment of their ability to make payments.

As a large multinational company with a long history of operating in a cyclical
industry, Schlumberger has extensive experience in working with its customers
during difficult times to manage its accounts receivable. During weak economic
environments or when there is an extended period of weakness in oil and gas
prices, Schlumberger typically experiences delays in the payment of its
receivables.  However, except for a $469 million accounts receivable write-off
during the fourth quarter of 2017 as a result of the political and economic
conditions in Venezuela, Schlumberger has not had material write-offs due to
uncollectible accounts receivable over the recent industry downturn.
Schlumberger generates revenue in more than 120 countries.  As of December 31,
2019, only three of those countries individually accounted for greater than 5%
of Schlumberger's net receivables balance, of which only one (the United States)
accounted for greater than 10% of such receivables.

Goodwill, Intangible Assets and Long-Lived Assets



Schlumberger records the excess of purchase price over the fair value of the
tangible and identifiable intangible assets acquired and liabilities assumed as
goodwill. The goodwill relating to each of Schlumberger's reporting units is
tested for impairment annually as well as when an event, or change in
circumstances, indicates an impairment may have occurred.

Under generally accepted accounting principles, Schlumberger has the option to
first assess qualitative factors to determine whether the existence of events or
circumstances leads to a determination that it is more likely than not that the
fair value of one or more of its reporting units is greater than its carrying
amount. If, after assessing the totality of events or circumstances,
Schlumberger determines it is more likely than not that the fair value of a
reporting unit is greater than its carrying amount, there is no need to perform
any further testing. However, if Schlumberger concludes otherwise, then it is
required to perform a quantitative impairment test by calculating the fair value
of the reporting unit and comparing the fair value with the carrying amount of
the reporting unit. If the fair value of the reporting unit is less than its
carrying value, an impairment loss is recorded based on that difference.

Schlumberger has the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to performing the quantitative goodwill impairment test.



During 2019, Schlumberger recorded an $8.8 billion goodwill impairment
charge. Refer to Note 3 to the Consolidated Financial Statements for details
regarding the facts and circumstances that led to this impairment and how the
fair value of each reporting unit was estimated, including the significant
assumptions used and other details.

Long-lived assets, including fixed assets, intangible assets and investments in
APS projects, are reviewed for impairment whenever events or changes in
circumstances indicate that the carrying value may not be recoverable. In
reviewing for impairment, the carrying value of such assets is compared to the
estimated undiscounted future cash flows expected from the use of the assets and
their eventual disposition. If such cash flows are not sufficient to support the
asset's recorded value, an impairment charge is recognized to reduce the
carrying value of the long-lived asset to its estimated fair value. The
determination of future cash flows as well as the estimated fair value of
long-lived assets involves significant estimates on the part of management. If
there is a material change in economic conditions or other circumstances
influencing the estimate of future cash flows or fair value, Schlumberger could
be required to recognize impairment charges in the future.

                                       21

--------------------------------------------------------------------------------

Income Taxes



Schlumberger conducts business in more than 100 tax jurisdictions, a number of
which have tax laws that are not fully defined and are evolving. Schlumberger's
tax filings are subject to regular audits by the tax authorities. These audits
may result in assessments for additional taxes that are resolved with the
authorities or, potentially, through the courts. Schlumberger recognizes the
impact of a tax position in its financial statements if that position is more
likely than not of being sustained on audit, based on the technical merits of
the position. Tax liabilities are recorded based on estimates of additional
taxes that will be due upon the conclusion of these audits. Estimates of these
tax liabilities are made based upon prior experience and are updated in light of
changes in facts and circumstances. However, due to the uncertain and complex
application of tax regulations, the ultimate resolution of audits may result in
liabilities that could be materially different from these estimates. In such an
event, Schlumberger will record additional tax expense or tax benefit in the
period in which such resolution occurs.

Revenue Recognition for Certain Long-lived Construction-type Contracts



Schlumberger recognizes revenue for certain long-term construction-type
contracts over time. These contracts involve significant design and engineering
efforts in order to satisfy custom designs for customer-specific
applications. Under this method, revenue is recognized as work progresses on
each contract. Progress is measured by the ratio of actual costs incurred to
date on the project in relation to total estimated project costs. Approximately
5% of Schlumberger's revenue in each of 2019 and 2018, respectively, was
recognized under this method.

The estimate of total project costs has a significant impact on both the amount
of revenue recognized as well as the related profit on a project. Revenue and
profits on contracts can also be significantly affected by change orders and
claims. Profits are recognized based on the estimated project profit multiplied
by the percentage complete. Due to the nature of these projects, adjustments to
estimates of contract revenue and total contract costs are often required as
work progresses. Any expected losses on a project are recorded in full in the
period in which they become probable.

Multiclient Seismic Data



Schlumberger capitalizes the costs associated with obtaining multiclient seismic
data. The carrying value of the multiclient seismic data library at December 31,
2019 and 2018 was $568 million and $601 million, respectively. Such costs are
charged to Cost of services based on the percentage of the total costs to the
estimated total revenue that Schlumberger expects to receive from the sales of
such data. However, under no circumstances will an individual survey carry a net
book value greater than a 4-year, straight-line amortized value.

The carrying value of surveys is reviewed for impairment annually as well as
when an event or change in circumstance indicates an impairment may have
occurred. Adjustments to the carrying value are recorded when it is determined
that estimated future revenues, which involve significant judgment on the part
of Schlumberger, would not be sufficient to recover the carrying value of the
surveys. Significant adverse changes in Schlumberger's estimated future cash
flows could result in impairment charges in a future period. For purposes of
performing the annual impairment test of the multiclient library, surveys are
primarily analyzed for impairment on a survey-by-survey basis.

Pension and Postretirement Benefits



Schlumberger's pension and postretirement benefit obligations are described in
detail in Note 17 to the Consolidated Financial Statements. The obligations and
related costs are calculated using actuarial concepts, which include critical
assumptions related to the discount rate, expected rate of return on plan assets
and medical cost trend rates. These assumptions are important elements of
expense and/or liability measurement and are updated on an annual basis, or upon
the occurrence of significant events.

The discount rate that Schlumberger uses reflects the prevailing market rate of
a portfolio of high-quality debt instruments with maturities matching the
expected timing of payment of the related benefit obligations. The following
summarizes the discount rates utilized by Schlumberger for its various pension
and postretirement benefit plans:

• The discount rate utilized to determine the liability for Schlumberger's

United States pension plans and postretirement medical plan was 3.30% at
      December 31, 2019 and 4.30% at December 31, 2018.

• The weighted-average discount rate utilized to determine the liability for


      Schlumberger's international pension plans was 3.27% at December 31, 2019
      and 4.00% at December 31, 2018.


   •  The weighted-average discount rate utilized to determine expense for
      Schlumberger's United States pension plans and postretirement medical plan
      increased from 3.70% in 2018 to 4.30% in 2019.


                                       22


--------------------------------------------------------------------------------

• The weighted-average discount rate utilized to determine expense for

Schlumberger's international pension plans increased from 3.55% in 2018 to

4.00% in 2019.




The expected rate of return for Schlumberger's retirement benefit plans
represents the average rate of return expected to be earned on plan assets over
the period that benefits included in the benefit obligation are expected to be
paid, with consideration given to the distribution of investments by asset class
and historical rates of return for each individual asset class. The weighted
average expected rate of return on plan assets for the United States pension
plans was 6.60% in 2019 and 7.25% in 2018. The weighted average expected rate of
return on plan assets for the international pension plans was 7.22% in 2019 and
7.40% in 2018. A lower expected rate of return would increase pension expense.

Schlumberger's medical cost trend rate assumptions are developed based on
historical cost data, the near-term outlook and an assessment of likely
long-term trends. The overall medical cost trend rate assumption utilized to
determine the 2019 postretirement medical expense and the postretirement medical
liability at December 31, 2019 was 7.50%, graded to 4.5% over the next twelve
years.

The following illustrates the sensitivity to changes in certain assumptions,
holding all other assumptions constant, for Schlumberger's United States and
international pension plans:
