ExxonMobil Guyana announced today that the gas compression and injection systems on the Liza Unity Floating Production, Storage, and Offloading (FPSO) vessel have been commissioned in record time and are planned for startup mid-next month.

The start-up period, the company said, involves temporary, non-routine flaring to safely commission the production and gas compression systems.

The Liza Unity FPSO arrived in Guyana last October and was undergoing commissioning.

Last year, ExxonMobil increased its flaring level on the Liza Destiny offshore Guyana when a compressor got damaged.  Despite efforts to repair and replace the damaged compressor, the flaring problems persisted and an entirely new system was expected to be installed.

The company is confident similar issues will not occur on its second FPSO.

“The Liza Phase 2 project design eliminates routine flaring by using produced gas to power the FPSO and by reinjecting gas into the reservoir to conserve the gas and to improve oil recovery, thereby reducing emissions compared with traditional methods. The team was also able to commission the water-injection system, which is now online and operational. The next step is to start up additional new wells in the ramp up to full production of 220,000 barrels of oil per day during the third quarter,” ExxonMobil said this afternoon.

This achievement the company said is a testament to its dedication to steady, safe operations and demonstrates its capabilities as an industry leader.

In addition, ExxonMobil has announced that a redesigned Flash Gas Compressor for the Liza Destiny FPSO has arrived in Guyana for installation after extensive testing in Germany.

“We have relentlessly pursued a solution to this highly complex issue and have never lost sight of that goal. We are pleased that the newly designed machine is now offshore and the teams are methodically removing the original machine in preparation for the upgraded Flash Gas Compressor installation and startup,” Exxon’s production Manager, Mike Ryan noted.

The company has explained that the performance of the second and third-stage flash gas compressor on the Liza Destiny has been stable and more than 96% of the gas produced was reinjected and/or used to power the vessel.

ExxonMobil Guyana continues to work with the relevant government agencies to ensure compliance with regulations and responsible development of the country’s natural resources.
