Anglo African Oil & Gas has announced that the TLP-103C well at its Tilapia licence located in offshore Republic of the Congo has encountered oil.
The well intersected the targeted Djeno horizon and wireline logging confirmed the presence of a 12m oil column in the Djeno.
With this discovery, the combined total of oil encountered by the TLP-103C well is at a 56m aggregate across the identified horizons.
Total depth (TD) of 2,683m was reached, following which Anglo African Oil & Gas ran Schlumberger wireline logs.
After completion of the logging, the company commissioned a CPI to calculate and qualify the results, which confirmed TLP-103C has encountered the oil column with a further 4m transition zone from 2,396m to 2,411m.
Anglo African Oil & Gas executive chairman David Sefton said: “To have encountered hydrocarbons in the Djeno at the first attempt is an excellent outcome and is testament to the quality of the geological model we put in place for Tilapia ahead of commencing drilling operations.
“While this well will produce from the Mengo and R2 rather than the Djeno, we have now encountered oil in all the targeted horizons, with a total combined oil of at least 56m, including a combined 44m of oil in both the Mengo and R2 and across discovered additional reservoirs.”
The company now intends to procure a new rig and drill the new TLP-104 well, which will specifically target bringing the Djeno into production.
It also intends to plan for full field development at Tilapia.
The results of the TLP-103C well will allow Anglo African Oil & Gas to enhance TLP-104’s well design as it seeks to optimise production from the Djeno.
Accordingly, the TLP-103C will be plugged back to the Mengo and then flow-tested and produced from the Mengo reservoir.
