BOEM just released their update of Gulf of Mexico OCS oil and gas reserves as of 12/31/2019. Oil reserves increased by 35.2% as a result of 6 new fields being added.
The reserve additions are necessary and welcome given the high depletion rates from 2002 to 2018 when reserves (plotted above) declined steeply while production rates held steady or increased. The concerns about the sustainability of current GoM production rates, as expressed in our 7/26/2021 post, remain given the historically low levels of exploratory drilling. For the reasons presented in that post, our view is that the importance of GoM production will increase, not decrease, over the next decade.
