Exxon Mobil Corporation ( XOM - Free Report ) has restored crude oil production offshore Guyana to the range of 80,000-90,000 barrels per day (bpd), after clearing up the technical glitch with the gas reinjection equipment. The director of Guyana's Environmental Protection Agency, Vincent Adams, confirmed about the production resumption at the site. Problems associated with the gas reinjection equipment, which is used to avoid excessive gas flaring, reduced production at the site by 65% to 27,500 bpd last week from early-May levels.
