Anadarko weighs up K2 booster



By Blake Wright 

US independent Anadarko Petroleum has kicked off a pre-front end engineering design study for an enhanced oil recovery project at its majority-owned K2 complex in the deep-water US Gulf.

According to the company, water injection, and injection of nitrogen or flue gas are all being evaluated in a bid to maintain K2's reservoir pressure and extend its life. Anadarko said earlier this year it lowered reserves expectations from the complex.

K2 and K2 North, in Green Canyon blocks 518, 561, 562, 563, 605, 606 and 607, are being developed via subsea wells tied back to the Marco Polo tension-leg platform.

Gross daily production this year has averaged just over 37,000 barrels of oil equivalent from six wells within the K2 complex.

The fields continue to experience nagging well glitches that have forced the operator to shut in a number of producers since the field came on stream in the middle of 2005.

Anadarko recently moved the Noble semi-submersible drilling rig Amos Runner to Block 518 to repair a failed subsurface safety value on the number-3 well. The well is scheduled to come back on stream later this quarter.

The well first came on stream last year at a rate of 9200 barrels of oil per day and 4.5 million cubic feet of gas per day.

Last year, the Block 562 number-3 well was shut in for several months after a subsea safety valve stuck shut.

Two delineation wells are planned at K2 this year. During the third quarter, the drillship Deepwater Millennium will spud a well in Green Canyon Block 606, while the semisub Belford Dolphin will drill a test in nearby Block 561.
