Tullow success at offshore Ghana appraisal

Kosmos Energy has announced that the Ntomme-2A appraisal well, located in the Deepwater Tano Block offshore Ghana, has successfully encountered significant quantities of light oil

The well, located over four kilometres south of the Tweneboa-3 sidetrack which discovered the Ntomme field, was designed to test the potential for an oil leg beneath the previously-identified gas-condensate at Ntomme. Results of drilling, wireline logs and fluid samples indicate that the well encountered 45 m of high-quality stacked reservoir sandstones, including 39 m of 35 degrees API gravity net oil pay. Pressure data from the well and the original discovery well suggests the potential for an oil column at Ntomme of approximately 125 m below the gas-condensate accumulation.

"The presence of a significant oil leg at Ntomme is a great result for Kosmos Energy,” said Paul Dailly, Senior VP of Exploration. "Ntomme was originally identified as a gas-condensate discovery; however, this well confirms the majority of resources to be oil. The result enhances both the momentum and value of our near-term development of the TEN project, which includes Tweneboa, Enyenra, and Ntomme. It is an excellent start to our active drilling program in 2012."

The Ntomme-2A well was drilled to an interim depth of 3,905 m in water of 1,730 m. The well is currently being deepened to a total depth of 4,010 m. Following the completion of drilling operations, a drill stem test of the well is planned.
