Oil: what happens when you defer or curtail production?

The aim of this data-file is to tabulate and track technical papers into the impacts of deferring production at oil and gas fields. The impact depends on the reservoir type, but generally we expect shut-ins and deferrals during the 2020 COVID crisis will lower effective production capacity.

The Winners. Generally, super-giant Middle East carbonate reservoirs and recently completed shale wells may fare well after curtailments and deferals, with production rates coming back higher than before the shut-ins.

The Losers. Restoring production may be more challenging at highly mature, heavy and waxy fields, particularly those with high water cuts or in deep water: where shut in, these fields may never recover to previous levels, while ramping back can take several years in some past cases.
