PRESS RELEASE

SHELF DRILLING REPORTS THIRD QUARTER 2021 RESULTS

Dubai, UAE, November 10, 2021 - Shelf Drilling, Ltd. ("Shelf Drilling" and,
together with its subsidiaries, the "Company", OSE: SHLF) announces results for
the third quarter of 2021 ending September 30. The results highlights will be
presented by audio conference call on November 10, 2021 at 6:00 pm Dubai time /
3:00 pm Oslo time. Dial-in details for the call are included in the press
release posted on November 3, 2021 and on page 3 of this release.

David Mullen, Chief Executive Officer, commented: "Our results in the third
quarter of 2021 were in line with the prior quarter, as we near the end of a
period with a high concentration of contract preparation activity. Five of our
rigs returned to operations after completing suspension periods or out of
service projects in recent months, and three additional contracts are scheduled
to commence in the first quarter of 2022, which we anticipate will drive
sequential improvements in revenue over the next two quarters. As of November
2021, 27 of our 30 marketable rigs are under contract."

Mullen added: "Based on the current strength in oil and gas prices and the
recent increase in tendering activity in our areas of operations, we expect to
see an improvement in global jack-up demand and pricing in the near term. With
our contract backlog and liquidity position, we believe we are well positioned
to capitalize on new opportunities in our sector."

Third Quarter Results

Revenues were $130.3 million in Q3 2021 compared to $130.5 million in Q2 2021.
The $0.2 million (0.2%) sequential decrease in revenues was primarily due to a
lower effective utilization partially offset by an increase in average earned
dayrate. Effective utilization decreased to 68% in Q3 2021 from 71% in Q2 2021,
mostly due to the completion of two contracts in the UAE and one contract in
India combined with planned out of service time for one rig in Saudi Arabia,
partially offset by the completion of an out of service project for one rig in
Saudi Arabia and the start of a new contract for one rig in India. Average
earned dayrate increased to $63 thousand in Q3 2021 from $60 thousand in Q2
2021, mainly due to increased activity for higher dayrate generating rigs.  

Total operating and maintenance expenses increased by $2.8 million (3.4%) in Q3
2021 to $84.5 million compared to $81.7 million in Q2 2021. The sequential
increase was primarily due to higher maintenance and shipyard expenses for three
rigs which were preparing for new contracts in India and West Africa, partially
offset by a reduction due to the sale of a rig in August 2021. 

General and administrative expenses of $12.0 million in Q3 2021 decreased by
$2.6 million as compared to Q2 2021 of $14.6 million mainly explained by a lower
provision for doubtful accounts. General and administrative expenses in Q3 2021
and Q2 2021 included $0.8 million and $1.1 million of non-cash share-based
compensation expense, respectively. 

Adjusted EBITDA for Q3 2021 was $33.9 million compared to $34.4 million for Q2
2021. The Adjusted EBITDA margin for Q3 2021 and Q2 2021 was 26%. 

Capital expenditures and deferred costs of $36.3 million in Q3 2021 increased by
$9.8 million from $26.5 million in Q2 2021. This increase was primarily due to
higher contract preparation expenditures on the Shelf Drilling Tenacious for a
contract in Angola expected to start in Q1 2022. In addition, equipment
recertification projects were completed on two rigs in Saudi Arabia between Q2
and Q3 2021.

Q3 2021 ending cash and cash equivalents balance of $251.3 million decreased by
$34.3 million from $285.6 million at the end of Q2 2021 primarily due to the
semi-annual cash interest payment in Q3 2021 on the 8.25% Senior Unsecured Notes
due February 2025 and cash payments for capital expenditures and deferred costs
during the quarter.

The Quarterly Report, which includes the Condensed Consolidated Interim
Financial Statements, and a corresponding slide presentation to address the
results highlights for Q3 2021 are available on the Company's website.
