Exxon Mobil expects lower production in Guyana’s Stabroek Block in the third quarter as it conducts hook-up work at two offshore developments that will supply a much-needed gas-to-energy project for power use on the country’s mainland.

Exxon expects gross volumes in Guyana will decrease by approximately 13%, or 80,000 bbl/d, due to scheduled work on Liza Phase 1 and Phase 2 FPSOs to enable the necessary gas-to-energy project tie-ins, company executives said during in its Aug. 2 second-quarter webcast.

To date, Exxon’s first three Stabroek developments—Liza Phase 1, Liza Phase 2 and Payara—and their associated FPSOs are producing over 600,000 bbl/d gross.

Exxon Mobil Guyana operates Stabroek and holds a 45% interest. Its local partners include Hess Guyana Exploration (30%) and CNOOC Petroleum Guyana (25%).

Gas production from Stabroek will be used to feed an onshore gas plant and allow Guyana to displace diesel fuel use in power generation, reducing emissions related to the use of the fossil fuel.

Stabroek gas will be sent onshore through a 130-mile pipeline network and associated infrastructure that will ship 50 MMcf/d of gas from the Liza Field to a 300-megawatt onshore power plant.

Exxon expects to complete pipeline construction and field hook-up by the end of 2024.

The Guyanese government will operate the plant.
