Exxon announces two new discoveries offshore Guyana

February 20th, 2019 – Georgetown, Guyana – an ExxonMobil release on the 6th of February announces two additional discoveries offshore Guyana in the Stabroek Block.

The discoveries are in the southeast of the block, in an area called Turbot (south of the Liza area, where previous ExxonMobil discoveries were made). The wells, Tilapia-1 and Haimara-1, are the 11th and 12th discoveries, giving a discovery success of over 80%, unheard of. Tilapia-1 is the 4th discovery well in the Turbot area (which includes the Longtail and Pluma discoveries).

These are significant discoveries, serving as reinforcing evidence that there will be potential for at least 5 floating, production, storage and offloading vessels (FPSOs) on the block by 2025.

Says Lars Mangal, CEO of TOTALTEC Oilfield Services, “As we continue to hear news of the discoveries offshore Guyana, it’s critically important to continue to develop local content; hiring Guyanese people, forming local business partnerships and using Guyanese facilities ensures sustainable development of the energy sector for the benefit of all our citizens.”

Developing the Stabroek Block – Liza and Payara

The Turbot discovery wells come after a suite of discoveries in the Liza area of the Stabroek block. The Liza Phase 1 development continues to develop on schedule, with production of 120,000 barrels per day on track for early 2020.

Government regulation and approval processes are expected for the Liza Phase 2 in Q1 of 2019, with production expected for mid-2022. A second FPSO will see the Liza Phase 2 kick off production on the Stabroek Block with an estimated 220,000 barrels per day. A 3rd development, Payara, an area north and west of the Liza areas also should receive regulatory approval in Q1 of 2019, with production expected later, in 2023.
