Guyana project overview

ExxonMobil initiated oil and gas exploration activities in Guyana in 2008, collecting and evaluating substantial 3-D seismic data that led to the company safely drilling its first exploration well in 2015, Liza-1.

Gas to Energy Project – Description

ExxonMobil is progressing plans for the Gas to Energy Project in cooperation with the Government of Guyana. Start up is expected by the end of 2024.
A successful project has the potential to significantly reduce the cost of electricity in Guyana.
The proposed project would bring associated gas from ExxonMobil Guyana-operated projects offshore (Liza Phase 1 and 2) via pipeline to onshore gas processing facilities. The pipeline would transport up to ~50 million standard cubic feet per day of natural gas to the facilities.
