Texaco starts up Galley field

April 13, 1998

Texaco North Sea U.K. Co. has began oil production from Block 15/23a Galley field and is already looking to extend the development. Galley was developed with a production semisubmersible previously used in Emerald field. Under this first phase of development, three wells will deliver oil and gas from Galley's northern and southern accumulations. Peak output from these wells is expected to be 35,000 b/d of oil and 50 MMcfd of gas. Galley has estimated reserves of 28 million bbl of oil and 40

Texaco North Sea U.K. Co. has began oil production from Block 15/23a Galley field and is already looking to extend the development.

Galley was developed with a production semisubmersible previously used in Emerald field. Under this first phase of development, three wells will deliver oil and gas from Galley's northern and southern accumulations. Peak output from these wells is expected to be 35,000 b/d of oil and 50 MMcfd of gas. Galley has estimated reserves of 28 million bbl of oil and 40 bcf of gas.

First-phase development is expected to last 4 years. Development of Galley's western and eastern accumulations is being planned by Texaco and will involve more subsea wells producing at peak 15,000 b/d. The semi has capacity to process 55,000 b/d of well fluids. After separation, oil is exported by pipeline to Flotta terminal in the Orkney Island by way of Texaco's Tartan platform.

Gas is sent to Tartan for transportation to St. Fergus terminal near Aberdeen for processing. Galley lies in 495 ft of water and produces from upper Jurassic sandstones at 13,000 ft.
