Anglo African Oil & Gas reported that following the successful work to disconnect, clean through and reconnect the flowlines to TLP-101 on the Tilapia block in the Republic of Congo, and testing of flow through the annulus, the well was then re-directed to production through the coiled tubing.
The well was successfully brought back on line and the flow rate immediately surpassed the previous rate of 35 bpd. The company is now allowing the flow rate to increase gradually until it achieves the maximum level of sustainable flow. The company advises that it is likely to take up to two weeks before the maximum flow rate is achieved and will update the market once that flow rate has been established.
In addition, Schlumberger conducted a successful intervention focused on the integrity of the perforations on well TLP-102. Following the intervention, oil and gas samples were taken at the surface and were sent to Total’s laboratory in Pointe Noire for testing. The gas test result has now been received and has confirmed the company’s evaluation that TLP-102 is now in contact with the reservoir. The pressure in the well has continued to increase steadily, and further than initially expected by Anglo African. As a result, the company will open the annular to test whether oil will flow unassisted. However, the company still expects that to achieve optimum flow rates from TLP-102 will, as originally planned, require mechanical assistance. Anglo African has on site a downhole pump that was procured for this purpose. Its insertion requires the use of equipment readily available in Pointe-Noir and does not need a drilling rig on site.
The company has also commenced drilling operations at the TLP-103 have commenced ahead of mobilization of the rig. The construction of the wellhead cellar and a 30″ Conductor case has been hammered in situ in preparation for drilling. The majority of long lead items have now cleared customs and are in country. The company has also procured two wellheads from FMC that have been prepared and tested and they are on site at FMC’s facility in Pointe-Noire.
Due to the size of the rig an additional access road to the site has been constructed. Finally, the rig itself is awaiting a pre-embarkation inspection by a third-party rig inspection team. A further inspection will take place following rigging up at Tilapia.
