Gulf of Mexico update

Through 2021 the federal waters of the northern Gulf of Mexico (OCS) have cumulative production of 23.4 Bbo and 193 Tcf.  The deepwater (water depths > 1000’ as defined by BOEM) has produced 10.2 Bbo and 23.5 Tcf while the shelf has produced 13.2 Bbo and 169.5 Tcf.  From a BOE standpoint, the GOM has primarily been a gas province, and the bulk of that production has come from shelf fields.  While the shelf has produced more cumulative oil than deepwater, over 90% of current oil production comes from deepwater fields. 

First production from the OCS occurred in 1947.  First deepwater production was in 1979 from Shell’s Cognac field in 1022’ of water.  GOM oil production in December 2021 was 1.69 mmbopd as per BSEE.  As Ovi says in his monthly updates, if GOM were a state, it would be the 2nd leading oil producing state in the US, only behind Texas.

Brief history of GOM gas production

GOM gas production peaked in 1997 at 14.4 bcf/day and has been declining ever since.  Current gas production is about 2 bcf/day.

Decline in World Conventional Oil Output and Peak Oil

World Conventional Oil output peaked at a centered twelve month average (CTMA) of 74193 kb/d in July 2016. This peak is unlikely to be surpassed in the future. I do not include an estimate of unconventional oil produced in Venezuela as this data is difficult to find. In the chart below, I compare World C+C output to World conventional oil, which I define in this post as World C+C minus the sum of US tight oil and Canadian oil sands. The units for most charts (figures 11 and 12 are exceptions) will be kb/d on vertical axes. Data for oil output in all charts that follow will be the centered twelve month average output. Data is from the EIA’s International Energy Statistics.
