Spill Description:
On June 23, 2025, a release was discovered at the Pluss L 11-2D wellhead. The cause of the release was due to pressure increase associated with offset completions activity. This resulted in fluids daylighting at the surface around the wellhead. Investigation and assessment activities are ongoing and will be summarized in a forthcoming Supplemental Form 19 Spill/Release Report. A topographic Site Location Map showing the geographic location setting of the release is provided as Figure 1.
