The Central Basin Platform is getting a boost despite nearing 100 years of activity thanks to horizontal drilling and completion techniques, which have dramatically increased production in the storied basin.
Even the Central Basin Platform’s Wasson Field, which discovery dates back almost 80 years, landed a spot on the Energy Information Administration’s 100 U.S. oil fields in 2015. The field is located in Gaines and Yoakum counties in West Texas.
The discovery well for the Wasson Field was drilled in 1937, to just over 5,000 feet, with production from the San Andres.
Central Basin formations currently producing from horizontal drilling include: Leonard, Yates, San Andres, Wolfcamp from the Permian, and Cisco, Canyon, Strawn and Atoka from the deeper Pennsylvanian.
Even though the basin is wedged between powerful Permian magnets—the Midland and Delaware basins—the Central Basin is still drawing interest.
In May, a lease sale by the New Mexico State Land Office drew a high bid of $257 million by Opal Resources II LLC for Central Basin Platform acreage, according to IHS Markit.
The company spent about $752 per acre for a 341.56-acre parcel taking in all of irregular Section 16-21s-38e in southeastern Lea County, N.M. The northern portion of the section contains two abandoned San Andres oil wells that produced from Littman Field as recently as 2013.
The eastern edge of the lease is adjacent to Andrews County, Texas (RRC Dist. 8), where Opal permitted a horizontal Wichita-Albany test late 2015. Also nearby in Andrews, Forge Energy LLC has a successful horizontal San Andres program.
