The Permian Basin of west Texas and New Mexico currently contains many of the most actively pursued unconventional plays in the world. The 75,000-square-mile continental depocenter is split into the Delaware Basin on the west and the Midland Basin to the east and is the largest petroleum-producing area in the United States. According to IHS Markit, the basin produced a record 815 million barrels of oil last year, 97 years after its first discovery. What is even more astounding is that as many as 1 million additional wells may remain to be drilled in the foreseeable future. Though production is on land and relatively shallow, the Permian Basin presents technical challenges in terms of complex stratigraphy, multiple play types, variable rock properties, and multiple periods of faulting, fracturing, and diagenesis.
