The Permian Midland system consists of approximately 6,600 miles of natural gas gathering pipelines and fourteen processing plants with an aggregate nameplate capacity of 2,129 MMcf/d, all located within the Permian Basin in West Texas. Ten of these plants and 4,800 miles of gathering pipelines belong to a joint venture (“WestTX”), in which we have an approximate 72.8% ownership. Pioneer, a major producer in the Permian Basin, owns the remaining interest in the WestTX system.
In addition, we are constructing the Gateway Plant, a new 250 MMcf/d cryogenic natural gas processing plant included as part of WestTX in the Midland Basin. The Gateway Plant is expected to begin operations in the fourth quarter of 2020.
