ExxonMobil Corporation announced minutes ago that it has discovered 256 feet of high quality, oil-bearing sandstone with its eight discovery well called the Longtail-1. In a statement to the media, the American multinational company said that this creates the potential for additional resource development in the southeast area of the Stabroek Block.

The oil giant noted that the well was safely drilled to 18,057 feet (5,504 meters) of depth in 6,365 feet (1,940 meters) of water.

President of ExxonMobil Exploration Company, Steve Greenlee said that the Longtail-1 discovery is close to the Turbot well which is southeast of the Liza field. He noted that drilling results of the eight well are under evaluation. Be that as it may, Greenlee noted that the combined estimated recoverable resources of Turbot and Longtail will exceed 500 million barrels of oil and will contribute to the evaluation of development options in the eastern portion of the Stabroek block.

ExxonMobil also reminded that it is currently making plans to add a second exploration vessel offshore Guyana in addition to the Stena Carron drillship, bringing its total number of drillships on the Stabroek Block to three. The new vessel will operate in parallel to the Stena Carron to explore the block’s numerous high-value prospects.

The company noted that the Noble Bob Douglas is completing initial stages of development drilling for Liza Phase One. This aspect of the ExxonMobil operations will consist of 17 wells connected to a floating production, storage and offloading (FPSO) vessel designed to produce up to 120,000 barrels of oil per day.

Phase Two concepts are similar to Phase One and involve a second FPSO with production capacity of 220,000 barrels per day. A third development, Payara, is planned to follow Liza Phase Two.

First oil is expected in early 2020.
