Overview

U.K. North Sea

Apache has interests in approximately 362,000 gross acres in the U.K. North Sea. The region contributed 13 percent of Apache’s 2017 production and approximately 11 percent of year-end estimated proved reserves.

Apache entered the North Sea in 2003 after acquiring an approximate 97-percent working interest in the Forties Field. Since acquiring Forties, Apache has actively invested in the region and has established a large inventory of drilling prospects through successful exploration programs and the interpretation of acquired 3-D and 4-D seismic data.

Building upon its success in Forties, in 2011, Apache acquired Mobil North Sea Limited, providing the region with additional exploration and development opportunities across numerous fields, including operated interests in the Beryl, Nevis, Nevis South, Skene and Buckland fields, and a nonoperated interests in the Maclure and Nelson fields. The Beryl Field, which is a geologically complex area with multiple fields and stacked pay potential, provides for significant exploration opportunity. The North Sea Region plays a strategic role in Apache’s portfolio by providing competitive investment opportunities and potential reserve upside with high-impact exploration potential.

During 2017, the region drilled 10 development wells with a 90-percent success rate: four at Forties, four at Beryl and two at Callater. In addition, it drilled or participated in four exploration wells with a 25-percent success rate. Exploration success over the past three years has averaged 50 percent.

Apache progressed on the 2015 Callater discovery in the Beryl area, with first production commencing in the second half of 2017. Apache holds a 55-percent working interest in Callater and operates the field. Appraisal and development plans continue to be finalized on the Seagull and Corona,  discoveries, while the more recent Storr discovery continues to be evaluated. Apache holds a 35, 100, and 35 percent interest in the Seagull, Corona and Storr discoveries, respectively.

In 2018, Apache plans to operate an average of three rigs in the North Sea Region, two platform rigs (one at Forties and one at Beryl) and one semi-submersible rig.
