Carbon-Zero US LLC of Dallas (a Cox Oil affiliate) has applied for up to $12 million in U.S. Department of Energy funds to develop a pilot sequestration hub in offshore storage fields about 20 miles from Grand Isle, according to officials from Cox Operating LLC, the Dallas operator that owns some of the storage fields.
Cox Operating LLC will “repurpose facilities and equipment” for the carbon storage project, according to a news release.
The Advocate
Should this company be authorized to repurpose Gulf of Mexico facilities for carbon sequestration?
- Per BSEE Incident of Non-Compliance (INC) data for 2022, Cox had more component shut-in INCs (132) than any other company. Cox was second to the Fieldwood companies in the number of warning and facility shut-in INCs, and in the total number of INCs. 48% of the Cox INCs required either a component or facility shut-in.
- Cox had an INC/facility-inspection ratio of 0.77, nearly 50% higher than the GoM average of 0.53.
- Per the posted BSEE district investigation reports for 2022, Cox was responsible for 9 of the 30 incidents that were significant enough to require investigation. That is more than twice as many as any other company (next highest was 4).
- The incidents included 3 serious injuries, 2 fires, a large gas leak, and oil spills of 114, 129, and 660 gallons. Per the posted reports, only one other company had an oil spill of >1 bbl. (Note: Only spills of > 1 bbl are routinely investigated by BSEE. One bbl = 42 gallons.)
- While INCs were issued for only 3 of the 9 Cox incidents, a review of the reports suggests that INCs should have been issued for at least 4 of the other incidents.
- Cox operates 375 platforms with installation dates as early as 1949. 134 of their platforms are > 50 years old. Only 66 were installed in the last 20 years and only 6 in the last 10 years (most recent December 2014). How will the carbon sequestration plans affect their massive decommissioning obligations?
- Many of the Cox platforms were assigned by predecessor lessees. Those predecessors can only be held responsible for the decommissioning of facilities they installed, not for more recent wells or platforms and not for facilities that are repurposed for carbon sequestration.
Other more generic issues should be addressed before DOE awards funds for offshore sequestration projects.
Also, as noted in the discussion of Exxon’s 94 Sale 257 oil and gas leases, a competitively issued alternate use RUE is required (30 CFR § 585.1007) before sequestration operations may be conducted on an oil and gas lease.
