Permian region

The Permian Region is one of Apache’s core growth areas with over 2.8 million gross acres with exposure to numerous plays focused primarily in the Midland Basin, the Central Basin Platform/Northwest Shelf and the Delaware Basin. Estimated proved reserves of 681 MMboe at year-end 2017, representing 58 percent of the Company’s worldwide reserves. Annual production of 157.8 Mboe/d declined only 2 percent from 2016. Fourth-quarter 2017 production increased 10 percent from the prior sequential quarter, a reflection of the success of the Midland Basin drilling program and continued production ramp up at Alpine High, which first came online in May 2017. In 2017, the Permian Region averaged 16 rigs and drilled or participated in 215 wells, 158 of which were horizontal, with a 97-percent success rate.

In September 2016, Apache announced the discovery of a significant new resource play, Alpine High. Apache's Alpine High acreage lies in the southern portion of the Delaware Basin, primarily in Reeves County, Texas. Read the release +

Apache plans to continue an elevated level of activity in the Permian Region during 2018, while continuing to balance capital investments between its larger development project at Alpine High and focused exploration and development programs on other core assets in its Permian region. During 2018, the company expects to average approximately 14 drilling rigs, which includes six to seven rigs at Alpine High focused on a combination of retention, development, and delineation drilling. Approximately $1.6 billion, or roughly two-thirds, of the Company’s 2018 capital upstream budget will be allocated to the Permian region. The company anticipates investment of $500 million in the midstream development of Alpine High in 2018.
