ExxonMobil Guyana is forging ahead with its Stabroek Block drilling program with two appraisal wells being targeted at the Haimara gas field, discovered five years ago.

This is according to a document published in Guyana’s Official Gazette.

The program includes the Haimara-3 and Haimara-4 appraisal wells.

Haimara-1 was Exxon’s 12th Stabroek Block discovery, announced back in February 2019. Exxon had encountered approximately 207 feet (63 meters) of high-quality, gas-condensate bearing sandstone reservoir. The discovery was so significant that Exxon had said that it is a potential new area for development. And its position near the Suriname border could allow for joint development across borders. 

Haimara-2 was drilled in September last year. Exxon did not announce a discovery there.

The drilling program also includes a well called Lau Lau-2.

The Lau Lau-1 discovery was made in 2022. Westwood Global Energy Group estimated the discovery to hold more than 100 million oil-equivalent barrels, with the presence of more gas than oil.

Guyana’s focus is beginning to shift to its natural gas potential. And Exxon is right in line with the government’s vision. The company is mulling whether its seventh Guyana development will pursue oil production, or perhaps, be the first standalone offshore gas development. 

Wells pursued already for the year include Redmouth-1, Hatchetfish-1, Trumpetfish-1 and Bluefin-1. Redmouth-2 is a potential extra well on the program, depending on the results of the first well.

Hatchetfish-1 was drilled back in February by the Noble Sam Croft. Exxon did not announce a discovery there. 

Bluefin-1 was Exxon’s first discovery this year. 

Trumpetfish-1 and Redmouth-1 are anchor-hunting wells, meaning they target new reserve bases for potential standalone developments. Both wells are located west of the Liza and Payara discoveries.
