ABIDJAN, Cote d’Ivoire – LUKOIL Overseas Cote d’Ivoire Ltd. together with Vanco Cote d’Ivoire Ltd. (Vanco) and PETROCI Holding, announces a discovery in Block CI-401. The Independance-1X exploration well drilled on Block CI-401 has penetrated the targeted objective and found a series of good-quality sandstones containing light oil and gas condensate. Full analysis of well results, including wireline logs, reservoir pressures and fluid samples, confirms that the well penetrated 8 meters (26 feet) of hydrocarbon pay in two good-quality Turonian-aged sand packages. Hydrocarbon samples recovered from the Independance-1X well indicate 40 degrees API gravity. The well will be temporarily abandoned at a total depth of 4,132 meters.

Independance-1X was drilled in a water depth of 1,689 meters, approximately 93 kilometers (58 miles) southeast of Abidjan. The Independance -1X is the second exploration well to be drilled in Block CI-401, which encompasses an area of 619 square kilometers (152,948 acres) in water depths ranging from 950 to 2,100 meters.
