Executives at the fourth-largest U.S. refiner by capacity said in a presentation to Wall Street analysts that next year's outlays would range from $3 billion to $3.5 billion, compared with the estimated $3.3 billion to $3.5 billion this year.

"Phillips 66 has a consistent, proven strategy to create value for shareholders," Chief Executive Greg Garland said in New York. "Our strategic priorities of growth, returns and distributions are supported by a strong foundation of operating excellence and a high-performing organization."

The 2019 capital budget was boosted in part by $300 million to pay for a retail-fuels joint marketing campaign with an undisclosed partner on the West Coast, executives said. Phillips markets fuels under the Phillips 66 and Union 76 brands.

"The transaction has not yet been finalized," said Phillips 66 spokesman Dennis Nuss. "We can confirm additional details once the transaction is closed."

At the high end of next year's spending, the company would have "$1.5 billion to $2.5 billion for share repurchases, ahead of our expectations of $1.2 billion," Credit Suisse analysts said in a note on Wednesday. "Another strong dividend increase for 2020 indicated (we expect a 10% hike)."

During the presentation, which was webcast, analysts questioned whether the capital budget fully reflected spending for major oil pipeline and other projects being constructed.

Garland said two major pipelines being developed were financed by shippers. Phillips 66 discloses its financing arrangements to credit rating agencies, he added, saying: "We're completely transparent."

Phillips 66's budget will include work on gasoline-producing fluidic catalytic cracking units (FCCU) at its Sweeny, Texas, and Ponca City, Oklahoma, refineries in 2020.

At the 265,000-barrel-per-day (bpd) Sweeny refinery south of Houston, Phillips 66 plans to continue modernizing the two FCCUs. Work at the 207,000-bpd Ponca City refinery in northern Oklahoma will focus on improving the yield from the FCCUs.

Also for 2020, the company is planning projects to produce diesel fuels from renewable resources at the 120,200-bpd Rodeo, California, refinery in the San Francisco Bay area and at the 221,000-bpd Humber, England, refinery.
