Kosmos discovers light oil at Akasa offshore Ghana

By Phaedra Friend Troy

Kosmos Energy (NYSE:KOS) has discovered light oil with the Akasa-1 exploration well on the West Cape Three Points Block offshore Ghana

The Atwood Hunter deepwater semisubmersible drilled the Akasa-1 discovery well to a total depth of 3,918 meters (12,854 feet) in waters measuring 1,158 meters (3,798 feet) deep. Wireline logs, reservoir pressures and fluid samples confirm that the Akasa-1 well transected 33 meters (108 feet) of oil-bearing pay in four good-quality Turonian-age sand packages. Oil samples recovered measure 38-degrees API. 

The Turonian reservoirs in the Akasa well are similar in age to those discovered in the Jubilee and Mahogany East oil fields. 

“With this find, we have enhanced our inventory of discovered resources, further supporting the appraisal and development programs in the Mahogany East and Teak areas,” said Paul Dailly, Senior Vice President of Exploration for Kosmos

Kosmos is intent on achieving first production from these projects, as well as from the oil discoveries at the adjacent Deepwater Tano Block. 

More Drilling Planned Offshore Ghana 

While the Atwood Hunter is being released to another operator after finishing the Akasa-1 well, Kosmos is planning near-term drilling at the Cedrela exploration prospect, which is currently under Force Majeure discussions. 

Kosmos also plans to drill two appraisal wells at the Teak discovery on the West Cape Three Points Block. 

Adiitionally, Kosmos and its partners plan to drill at least two appraisal wells at the Enyenra field on the Deepwater Tano Block. 

Tweneboa Well Flows Strong Oil, Supporting Another Development 

Kosmos also reported that the Tweneboa-4 well on the Deepwater Tano Block flowed at sustained rates of 3,500 barrels of condensate and 30 million cubic feet of natural gas a day. 

Additionally, a drill stem test of the Tweneboa-2 well reached flow rates of 6,500 barrels of oil a day with 5 million cubic feet of natural gas a day. 

Kosmos and its partners are using these results to support development plans for the Tweneboa-Enyenra complex. 

Kosmos serves as the operator of West Cape Three Points Block with 30.875 percent interest. Anadarko holds 30.875 percent, Tullow Oil holds 26.396 percent, Sabre Oil & Gas holds 1.854 percent, and the Ghana National Petroleum Corporation holds a 10 percent carried interest in the block. 

On the Deepwater Tano Blcok, Tullow Oil is the operator with 49.95 percent interest. Kosmos Energy holds 18 percent in this block. Other project partners include Anadarko with 18 percent, Sabre with 4.05 percent and Ghana National Petroleum Corporation with a 10 percent carried interest.
