Well, I guess it depends on which job losses are attributed to COVID-19.
The Oil Patch was already on the ropes because of the shenanigans the Russians and Saudis pulled. THose jobs aren't gone over COVID-19, but over low oil prices (that' would have caused massive layoffs in the drilling end of the business, and every drilling rig that shuts down means a slew of other jobs are in peril, for every four or five, expect jobs to be lost. Not only are the drilling company employees laid off, supervisory staff, geological and directional personnel, Drilling fluid engineers, truckers, water haulers, the people who rent out site housing and maintain it, earthwork contractors, feeder pipeline companies, etc., the list goes on. All the people who worked in the industries which supply the drilling operations lose jobs, and so forth. Those jobs won't be coming back for a while, not until the current surplus is used up, not until demand is back, and the price increases. Some will perhaps be back in a year. (perhaps).
Completions will likely lag as well, because there is no sense in spending the money to complete a well (fraccing, surface equipment, downhole production equipment) when the product will sell for less than it cost. Time easements have been given to permit oil companies to wait to complete DUC (Drilled but UnCompleted) wells.
Companies involved in doing completions will suffer some. Some will be involved in slowing production or shutting wells in for a while.
In the midstream, transportation/storage will go on, and staff will likely be mostly retained.
In the refining end, there have been slowdowns, and there may be furloughs there as well.
Those jobs affect other jobs, indirectly, but some of those jobs are also affected by COVID restrictions.
Just pointing out that not every job dies of the Coronavirus, just like not every patient. Expect some book cooking there, too.
