Since well before the Putin crisis, this independent blog has been expressing concerns about sustaining US offshore oil and gas production without new leases and increased exploration (more here). Now that concerns about domestic production and energy security are heightened (understatement of the year!), let’s review where the leasing program stands:

  • 466 days have elapsed since the last oil and gas lease sale (Nov. 19, 2020), with no future sales in sight.
  • There had been 182 sales in the previous 66 years of the US offshore oil and gas program, an average of 2.76 per year. Never before (since 1953) has a year transpired without a lease sale.
  • Currently, there are only 2016 active US OCS leases and 506 producing leases, the fewest in at least 40 years (recent history charted below).
  • Despite favorable geology beneath the deepwater Gulf of Mexico and advanced exploration and well completion technology, US offshore oil production (1.713 million bopd per the latest EIA data – Dec. 2021) is down 16% from the August 2019 peak of 2.044 million BOPD. Gulf oil production is thus the lowest since 2018 (except during hurricane shutdowns).
  • New projects and higher ultimate recoveries from producing reservoirs could increase total offshore production by 10-20% over the next few years, but sharp declines will follow without new leases and increased exploration.

The rig count remains low at 12 (see the updated chart below). Per BSEE’s borehole file, only 3 deepwater exploratory wells have been spudded in 2022 YTD (2/21) – one each for Shell, Hess, and Anadarko.

What’s going on? Better opportunities elsewhere? Uncertainty about lease sales? Concerns about legal challenges and the future of the US offshore program?

Our last GoM update predicted November oil production of 1.8 million BOPD. The EIA figure released yesterday came in slightly less than that at 1.795 million BOPD.

Will 2022 startups push oil production back up to the 2.044 record achieved in August 2019? Possibly, but the longer term outlook is not compelling given reduced drilling activity and the dearth of recent discoveries. The long leasing pause will further compromise exploration by limiting opportunities to test new geologic interpretations and assess promising prospects.

Yesterday, BSEE issued investigation reports for 2 of the fatal 2020 incidents. Both of these incidents involved falls, a chronic and preventable cause of offshore worker casualties. Not enough industry and trade association attention is given to such incidents, which have been trivialized in the past by categorizing them as “slips, trips, and falls.” The reports are linked below:

The reports describe how the incidents occurred and what we can do better to prevent similar events in the future. Despite the advance in safety management programs over the past 30 years, there has been no discernible improvement in preventing these incidents. We need to rethink training programs, planning, and methods. Deadly falls are not inevitable.

EIA data

October production rebounded to 1.744 million BOPD from the 2021 low of 1.064 million BOPD in September (Hurricane Ida). November and December production should exceed 1.8 million BOPD.

Per Offshore-Energy.biz, BP’s semi-submersible Argos production platform has arrived on location in the Gulf of Mexico. The floating platform will operate in 4500′ of water as part of BP’s Mad Dog 2 project. Production, which is expected to reach 140,000 boe/d, should begin in the 2nd quarter of 2022.

Per BOEM’s platform data base, this will be the 58th surface production facility in the deepwater (>1000′) GoM and the first such facility installed since Shell’s Appomattox in June, 2018. These platforms account for more than 90% of US offshore oil production.

Data from EIA

More than half of GoM oil production was shut-in for 13 days in September and several hundred thousand BOPD were shut-in for the rest of the month. The result was a 42% reduction in production from pre-Ida (July) levels.

All production has now been restored so the December EIA figures should give us a good read on stablized post-Ida production.

U.S. To Sell Area the Size of New Mexico For Offshore Drilling Just 5 Days After COP26

Newsweek
  • 80 million acres is the total area in the Gulf of Mexico that is open for possible leasing in Sale 257. The area receiving bids will be only a small fraction of that.
  • In the previous sale (256), which was almost exactly one year ago, the same area was open for sale and only 0.6% of that area received bids. Only 93 of the nearly 15,000 tracts offered received bids. 7 of the high bids were rejected, so only 86 new leases were issued.
  • There are currently only 2,027 active GoM leases (10.8 million acres), less than half the number that existed in 1/2016 (4460) and less than 1/3 the number that existed in the beginning of 2011.
  • US offshore leases are among the smallest in the world, only a fraction of the sized of those offered by most other nations with offshore oil and gas programs.
  • Modern deepwater development is noteworthy for high production from very few platforms. Only 57 surface facilities account for more than 90% of current GoM oil production.

Which platform is pictured in the International Space Station photo (re-posted below)? It is clearly a spar (basically a large vertically floating cylinder), and like most GoM spars appears to be the truss type (see diagram below depicting spar types). There are currently 18 GoM spars (list in table below). Looking at photos of these spars, my guess is that the SpaceX Dragon is pictured above Perdido (bottom photo).

  • Chart 1: Gulf of Mexico rig count remains low
  • Chart 2: Exploratory drilling continues to decline and may be insufficient to replace reserves
  • Chart 3: Well starts and number of operators drilling remain at historic low levels
  • Chart 4: (1) One company (Shell) accounted for 39% of the 2021 YTD deepwater well starts in the GoM. (2) Five companies (Shell, Oxy/Anadarko, Chevron, Murphy, and BP) accounted for 80% of the deepwater well starts.

More certainty regarding lease sales would help. Prospective participants need assurances that they will have opportunities to apply findings and test exploration and development strategies. Will Lease Sale 257 be held on schedule next week?
