We are committed to exiting our projects as responsibly as we begin them. In 2016, 411 wells were decommissioned and 178 tank battery facilities were removed in the DJ Basin and sites are being returned to vegetation; in our Texas operations 26 wells were decommissioned and the land brought back to its original state.
In the decommissioning process, we use standard operating procedures for the assessment and remediation of sites after the discovery of leaks or spills (including historic leaks or spills). In the DJ Basin, we discovered and reported 80 historic unintentional releases.
Offshore, we worked to decommission three subsea fields during 2016. The project included plugging and abandoning four subsea wells. Work to decommission subsea infrastructure for these wells occurred in phases throughout 2016 with final pipeline decommissioning operations in 2017.
