BSEE’s decommissioning notice has been posted

Posted in decommissioning, Gulf of Mexico, Offshore Energy - General, Regulation, tagged , , , on November 8, 2022| Leave a Comment »

BSEE’s temporary abandonment/decommissioning solicitation has been posted. Some details:

  • 14 wells to be decommissioned
  • 1 well to be checked to confirm temporary abandonment
  • Well depths: 2359′ to 11934′
  • Water depths: 70′ to 477′
  • 11 gas wells, 3 oil wells
  • Well completion dates: 2006-2008
  • Last production: 2010-2013 (Presumably, the short productive life of these wells either contributed to or was because of the lessees’ bankruptcies.)
  • $25,000😀 minimum to $100,000,000 maximum contract guarantee

If I was an offshore contractor, I wouldn’t touch this work without:

  1. Ironclad liability protection after the work is completed and inspected. A contractor should not inherit the perpetual liability that the lessees knowingly and willfully accepted when they purchased the leases and conducted operations; nor is the contractor responsible for the failure of industry and government to establish a financial assurance framework that protects the taxpayer from such liabilities.
  2. Protection against likely cost overruns related to the uncertain downhole condition of the wells.

Six years of ONRR GoM flaring data summarized below

Posted in climate, energy policy, flaring and venting, gas, Gulf of Mexico, Offshore Energy - General, tagged , , , , on November 3, 2022| Leave a Comment »

Gulf of Mexico flaring and venting data have been sorted for the years 2015-2021. The reporting of these data is mandatory and strictly enforced, so these ONRR numbers should be accurate.

Biggest surprise: The biggest surprise is that there were no big surprises in the data. The % of gas flared and vented were generally consistent with expectations based on familiarity with historical data.

Biggest disappointment: the continued sharp decline in nonassociated (gas-well) gas production. GoM gas well gas production exceeded 4 tcf annually in the 1990s and was still above one tcf ten years ago. Since then, GWG production has declined by 80%. Nonassociated offshore natural gas has important environmental advantages, so the decline in production should be a major concern to policy makers

Encouraging sign: The % of oil-well gas vented has ticked down over the past 2 years which is encouraging from a GHG standpoint. This is presumably because most associated gas is produced on modern deepwater facilities equipped with flare booms. An astute politician would be rushing to take credit for this achievement.😀

Unfavorable ratio: Although the volumes are low (<1 Bcf combined in 2021), more gas-well gas was vented each year than flared. This is presumably because older shelf facilities without flare booms still produce much of the natural gas.

  • GoM: Federal waters of the Gulf of Mexico
  • OWGP: oil-well gas production

Gulf of Mexico production remains stable; BOEM forecast misses the mark

Posted in energy policy, Gulf of Mexico, Offshore Energy - General, tagged , , , on November 2, 2022| Leave a Comment »

BOEM’s 2022 production forecast, which was just published in July, was 1.9 million BOPD, and will likely be a full 10% too high for the year. One has to assume that the staff work was completed well before the document was actually published. Of greater concern, BOEM’s longer term production forecast, along with unrealistic expectations for the “transition,” were used to justify a subminimal 5 year leasing plan with the fewest sales in history.

While we are looking at GoM methane releases…

Posted in climate, gas, Gulf of Mexico, natural gas, Offshore Energy - General, tagged , , , on October 27, 2022| Leave a Comment »

NASA has identified 50+ super-emitters of methane including sites in Turkmenistan (image below) that emit an estimated 111,000 pounds per hour.

 

By comparison, vented Gulf of Mexico methane emissions in 2021 totaled 1953 mmcf. This converts to 82 million pounds at atmospheric pressure and 60°F. The identified Turkmenistan sources would thus release the amount of methane in a month that all Gulf of Mexico facilities vent in a year (2021).

East of Hazar, Turkmenistan, a port city on the Caspian Sea, 12 plumes of methane stream westward. The plumes were detected by NASA’s Earth Surface Mineral Dust Source Investigation mission and some of them stretch for more than 20 miles (32 kilometers).

Gulf of Mexico flaring & venting – 2021

Posted in flaring and venting, gas, Gulf of Mexico, natural gas, Offshore Energy - General, tagged , , on October 26, 2022| Leave a Comment »

ONRR mandatory production reporting data are being sorted to assess GoM flaring and venting trends. This will help resolve inconsistencies previously identified. In the meantime, the table below summarizes the 2021 data. 1.03% of the gas produced that year was flared or vented. 0.25% of the gas production was vented.

Interestingly, more gas-well gas was vented than flared. This is presumably because older shelf facilities without flare booms still produce 25% of the gas (versus only 7% of the oil), mostly from gas wells. More to follow.

What’s next for Exxon’s sequestration leases?

Posted in CCS, Gulf of Mexico, tagged , , , on October 25, 2022| Leave a Comment »

Offshore

Per BOEM’s leasing data base, all 94 of the Sale 257 “carbon sequestration leases” (blue) were issued with an effective date of 10/1/2022. However, Sale 257 was an oil and gas sale, and the leases do not convey carbon sequestration rights. Each lease will expire in 5 years absent oil and gas production or ongoing drilling operations.

These oil and gas leases may not be repurposed for sequestration or other purposes unless an alternate use RUE is issued competitively in accordance with 30 CFR § 585.1007.

So what’s next for these 94 leases, 31% of the entire sale?

ONRR is now posting complete flaring and venting data

Posted in flaring and venting, gas, Gulf of Mexico, tagged , , , , on October 24, 2022| Leave a Comment »

Kudos to ONRR for posting complete flaring and venting data for all oil and gas operations on US Federal and Indian lands. These data, which distinguish between oil-well gas and gas-well gas, are included in the large “Production Disposition by Month” file that can be downloaded here.

The data should give us a good read on flaring and venting trends and help resolve the inconsistencies previously identified.

NOT a shining moment for the offshore industry

Posted in decommissioning, Gulf of Mexico, Offshore Energy - General, tagged , , , on October 21, 2022| Leave a Comment »

Where is the leadership? Offshore decommissioning costs should never fall on the taxpayer. See the attached notice (excerpt below) and a previous post on this topic.

BSEE intends to execute a multi-award IDIQ Quantity Contract inclusive of a Base Year and Four (4) Option Years; however, the government reserves the right to award the IDIQ contract to a single firm. Time & Material, Labor Hour, and/or firm-fixed price task orders will be awarded for Decommissioning Services necessary to take nine (9) orphaned facilities, located in the OCS of the Gulf of Mexico, to the point of Temporary Abandonment (TA). The estimated decommissioning cost for temporary abandonment is $10,000,000 to $20,000,000.

Just as the comment period on BOEM’s 5 year leasing program closes (today), OPEC (again) reminds us of the importance of US production

Posted in climate, energy policy, Gulf of Mexico, Offshore Energy - General, tagged , , on October 6, 2022| Leave a Comment »

Planned obsolescence, as justification for the minimalist leasing program (see below), is neither prudent nor consistent with the OCS Lands Act.

“The long-term nature of OCS oil and gas development, such that production on a lease can continue for decades makes consideration of future climate pathways relevant to the Secretary’s determinations with respect to how the OCS leasing program best meets the Nation’s energy needs.“

5 Year Leasing Program, p.3

Basing offshore leasing decisions on “future climate pathways” is a high risk strategy that may be inconsistent with the recent SCOTUS decision in West Virginia vs. EPA. A planned or phased shutdown of the offshore oil and gas program would dramatically increase economic and security risks, and has not been authorized by legislation.
