Wellman

The Wellman Field (WF) CO₂ storage project is a combined enhanced oil recovery (EOR) and geologic sequestration operation operated by CapturePoint LLC in Terry County, Texas within the Permian Basin. The field was discovered in 1950, with oil production beginning the same year from the Wolfcamp Reef (WLFRF) carbonate reservoir. A waterflood was initiated in 1979 to maintain reservoir pressure and move hydrocarbons toward the structural crest, followed by the start of CO₂ flooding in 1983, where CO₂ is injected at the top of the structure for vertical displacement and recovery of residual oil. The reservoir consists of a geologically well-defined oil-bearing reef system that has undergone primary production, waterflooding, and now CO₂ flooding, making it a suitable target for CO₂ capture and sequestration combined with EOR. Forecast modeling using a dimensionless performance curve approach estimates total CO₂ injection of approximately 100 million tonnes over the project life through 2061,
