Anglo African Oil & Gas to drill further well at Tilapia offshore field, Congo


Anglo African Oil & Gas is set to drill the TLP 103 well as part of its operations in the Tilapia offshore oilfield in the Republic of Congo. 

The well will target production from R1/R2 and the Mengo horizon and will also assess Djeno horizon's potential.

In addition, the company is working to optimise production from the existing TLP 101 and TLP 102 wells.

To drill the new well TLP 103, Anglo African Oil & Gas’ operations team has selected the preferred rig contractor following a detailed evaluation and tender process. 

The company expects to complete negotiations with all contractors by the middle of next month.

The preferred rig is already located in Republic of Congo and drilling of TLP 103 well is expected to take around 45 days. 

"At TLP 101, the company carried out a physical inspection of the wellhead and found a significant amount of detritus material in the line that has significantly reduced production."

After completing a technical evaluation, Anglo African Oil & Gas has opted to use fishbones technology to stimulate and complete the Mengo horizon in TLP103. This technology uses multiple small diameter lateral jets or drills from the wellbore to penetrate the reservoir and encourage production.

At TLP 101, the company carried out a physical inspection of the wellhead and found a significant amount of detritus material in the line that has significantly reduced production.

The company previously opted to install a pump to improve production from the well, but currently looks to resolve the issue of detritus material. 

Anglo African Oil & Gas has also re-perforated TLP 102, which confirmed the presence of hydrocarbons and pressure within the shallower R1 and R2 horizons. 

By assessing data procured from a pulse neutron log before the re-perforation, the company confirmed the presence of producible hydrocarbons that requires further mechanical intervention to restart production.
