Royal Dutch Shell Plc (NYSE: RDS.A) and Anadarko Petroleum Corp. (NYSE: APC) are renegotiating their five-year-old joint venture (JV) in the Permian Basin in Texas, Shell's CFO Simon Henry said on Feb. 2.

The 50-50 JV in the Delaware Basin, which expires in 2017, will likely see the operatorship of the asset "consolidated in a different way", Henry said in an earnings presentation to analysts.

Henry also said that Shell's position in the Haynesville Shale to the east of the Permian, which it acquired through its takeover of BG Group in 2016, "won't necessarily stay in our portfolio."

Shell is in the midst of a $30 billion global asset disposal program and previously said it has put up for sale two assets in its U.S. shale portfolio.

Shell plans to make its shale operations in North America and Argentina a major production growth engine in the 2020s.

On Feb. 2, it said it plans to grow its production in the Permian, and in the Fox Creek Basin in Canada, by about 140,000 barrels per day of oil equivalent in the near-term.

Oil majors including ExxonMobil Corp. (NYSE: XOM) and Statoil ASA (NYSE: STO) have significantly increased their stakes in U.S. shale in recent months as they seek to profit from the relatively short time and low spending it takes to ramp up production.
