HOUSTON – Cobalt International Energy, Inc. has provided an update on the status of its Cameia #2 appraisal well, located in block 21 offshore Angola.
The objectives of Cameia #2 were to better define the areal extent of the Cameia discovered resources, determine an oil-water contact deeper on the Cameia structure than the lowest known oil observed in Cameia #1, and test deeper oil potential in untested zones in the Cameia field.
Based on its preliminary wireline logging results, Cobalt says that Cameia #2 was successful on the first and second objectives, and evaluation is ongoing to determine the potential of the deeper reservoir target.
The well was drilled approximately 3.5 km (2.17 mi) south from the Cameia #1 presalt discovery well to the target total depth of 5,475 m (17,962 ft) in basement. Logging results have confirmed the presence of a large hydrocarbon accumulation in a high quality reservoir, and confirmed lowest known oil to be at least 135 m (443 ft) deeper than that which was observed in Cameia #1.
Analysis of data obtained from drilling operations and wireline logging indicates hydrocarbon charge and pressure separation from the uphole reservoir section in the deepest reservoir target.
Cobalt says it is currently preparing for a production drill stem test to be performed in August. It will then evaluate the results of all data collected to determine the reservoir potential, if any, of this new zone.
