Tall Oak Midstream LLC has begun initial natural gas gathering operations on the Tall Oak STACK System, which is designed to serve producers in Oklahoma's STACK play, also known as the Sooner Trend. The play is northwest of Oklahoma City and targets the Woodford and Mississippian-age shales. Tall Oak is gathering gas on the system for multiple customers and expects to commission the system's first processing plant, the Chisholm Plant, in the third quarter. The STACK System serves producers targeting the STACK play's liquids-rich pay zones, including the Upper and Lower Mississippian Meramec, Osage, Woodford Shale and Hunton formations. The system will also have the capacity to serve production from the Woodford and Springer shale plays and other portions of the South Central Oklahoma Oil Province, known as SCOOP.
Pioneer Natural Resources Co. on Tuesday said that severe winter weather in West Texas has significantly impacted production and drilling operations in the Spraberry/Wolfcamp area. At the beginning of January, the Spraberry/Wolfcamp area experienced heavy icing and freezing temperatures, which have resulted in "extensive power outages, facility freeze-ups, trucking curtailments and limited access to production and drilling facilities," the company said. "An extensive recovery period is expected, and it is likely to be several weeks before the full impact of this event can be determined." An operations update is to be provided along with fourth quarter results on Feb. 10. Fourth quarter Spraberry/Wolfcamp production was not impacted by the recent severe weather.
