Abstract
Abstract: Depositional Environments of Pennsylvanian Carbonates in the Arenoso Sub-
Basin
(Strawn, Arenoso Field, Winkler Co, Texas)
Abstract
The Arenoso Sub-Basin is located in a structurally low area on the western flank of the central basin platform in southeast Winkler County, Texas. The sub-basin has been a highly studied area since first discovered in 1963 by Humble Oil Company in an Ellen-burger wildcat. To date there has been over 25 million barrels of oil and 30 billion cubic feet of natural gas produced. The majority of this production is sourced from a succession of Pennsylvanian-aged rocks that consist mostly of restricted and open marine carbonates as well as detrital conglomerates sourced from Mississippian-aged shelf carbonates and Devonian-aged chert sediments eroded from nearby uplifts along the flanks of the sub-basin. Depositional facies that are seen include: ooid shoal grainstones, skeletal packstones, algal-pelletal wackstone/packstone, mudstone, and chert conglomerates. These representative facies will be examined in a series of 5 cores taken throughout the Arenoso Sub-Basin
