The world’s five largest oil companies collectively cut the value of their assets by nearly $50 billion in the second quarter, and slashed production rates as the coronavirus pandemic caused a drastic fall in fuel prices and demand. The dramatic reductions in asset valuations and decline in output show the depth of the pain in the second quarter. Fuel demand at one point was down by more than 30% worldwide, and still remains below pre-pandemic levels. Several executives said they took massive writedowns because they expect demand to remain impaired for several more quarters as people travel less and use less fuel due to the ongoing global pandemic that has killed more than 700,000 people. Of those five companies, only Exxon Mobil did not book sizeable impairments. But an ongoing re-evaluation of its plans could lead to a “significant portion” of its assets being impaired, it reported, and signal the elimination of 20% or 4.4 billion barrels of its oil and gas reserves. By contrast, BP took a $17 billion hit. It said it plans to re-center its spending in coming years around renewables and less on oil and natural gas. Weak demand means oil producers must revisit business plans, said Lee Maginniss, managing director at consultants Alarez & Marsal.
