Eni makes oil discovery offshore Ivory Coast
Published by Nicholas Woodroof,
The discovery well has been drilled on the Baleine prospect, with the support of the Ivory Coast Government. Baleine-1x discovered light oil (40° API) in two different stratigraphic levels. An evaluation programme will be carried out to assess the significant upside potential of the overall structure that extends into block CI-802, also operated by Eni with the same joint venture and participating interests in the exploration phase.
The well was drilled about 60 km off the coast, in about 1200 m of water depth with the Saipem 10 000 drill ship and reached a total depth of 3445 m in 30 days.
The Baleine-1x well was located on the basis of a comprehensive analysis of a wide range of 3D seismic data and regional studies in the sedimentary basin in Ivory Coast; the implementation of state-of-the-art technology including intelligent wireline formation testing and fluid sampling proved the presence of light oil bearing intervals of Santonian and Cenomanian / Albian age. The lower Cenomanian / Albian level shows discrete to good reservoir characteristics and has been successfully tested to production. Along with the appraisal programme, Eni and Petroci Holding will also start studies for a fast-track development of the Baleine discovery. The potential of the discovery can be preliminarily estimated at between 1.5 and 2 billion barrels of oil in place and between 1.8 and 2.4 trillion ft3 of associated gas.
Baleine-1x is the first exploration well drilled by Eni in the Ivory Coast. Besides block CI-101, Eni owns a participating interest in other four blocks in the Ivorian deep water: CI-205, CI-501, CI-504 and CI-802, all with Petroci Holding.
