Tilapia Well Encounters Hydrocarbons

Thursday, January 31, 2019

Anglo African Oil & Gas’ TLP-103C well on the Tilapia license in the Republic of Congo (ROC) hit hydrocarbons while drilling. The company said the well intersected the targeted Djeno horizon encountering hydrocarbons.

 

Wireline logging confirmed the presence of a 12-meter oil column in the Djeno proving a functioning reservoir in this formation in the Tilapia permit area. This discovery brings the combined total of oil encountered by the well to an aggregate of 56 meters across the identified horizons.

TD of 2,683 meters was reached on January 26 and over the course of the weekend the company ran Schlumberger wireline logs. Having completed logging Anglo African commissioned a CPI to calculate and qualify the results. This CPI was completed by Schlumberger on January 29. The results of the CPI confirm TLP-103C has encountered a 12-meter oil column with a further 4-meter transition zone from 2,396 meter to 2,411 meter in a dolomitic interval with a high content of shale. The interval is of Neocomien age.

In addition, the company said there are several smaller potentially oil-bearing intervals which have been difficult to precisely identify due to a mud build up on the calliper. The data gathered from the well will, subject to funding, enable the company to optimize the location of planned well TLP-104 in order to produce from the Djeno reservoir at optimal levels.

In a statement the company said that it was “confident that there is also a further Djeno reservoir below the current drilled depth which is prognosed to be in sandstone”. It intends to test this secondary reservoir target with the TLP-104 along with the Vandji formation. Due to poor performance of the rig throughout the well, the company has decided for safety reasons not to attempt to drill further with this equipment. Accordingly, the company intends to commission a new rig to drill TLP-104.
