Foremost energy experts like Daniel Yergin understand that oil and gas will be critical to our economy and security for decades, and that offshore production is an important component of our energy supply chain. Unfortunately, our massive outer continental shelf has, from an oil and gas standpoint, been effectively reduced to the central and western GoM.
Opportunities in the GoM are being seriously constrained by the extended pause in leasing. A lease sale has not been held for 615 days, the longest US offshore leasing gap since the 1950’s.
Reserve replacement and sustained production are dependent on exploration. The charts below illustrate the decline in GoM exploratory drilling and the reduced activity by some of the more important operating companies.
Per BSEE data, the number of exploratory well starts averaged only 3/month for the last 18 months (chart 2). This level of activity is the lowest since the early days of deepwater operations (chart 1). There was even more drilling during the post-Macondo moratorium (2010-2011).
ConocoPhillips and Exxon have not drilled a GoM exploratory well since 2016 and 2018 respectively. Activity by other operators has also declined significantly (chart 3). BP has not spudded an exploratory well since Sept. 2021.
No one should be surprised by the sharp decline in reserves and the dearth of recent field discoveries. Hopefully, government and industry will engage in a more thorough discussion of these trends and measures that might improve the intermediate and longer term production outlook.
