Abstract
The Gulf of Mexico (GoM) accounts for 20% of the production of the USA. Its deep part contains several plays with high potential resources. Those plays, trigger more interest from the research and the operation communities in the last years, and several billion dollars of budget have been allocated to the development of those deep offshore plays. The lower tertiary Wilcox trend, which extends from Alaminos Canyon to Keathley Canyon, is among those plays. It contains between 3 and 15 billion barrels of reserves. In 2009, Repsol drilled a discovery well in the Keathley Canyon, and encountered more than 1,000 foot hydrocarbon column at 27,000 depth and 6,000 feet of water. Three appraisal wells were drilled afterwards, and confirmed the high potential of this prospect. However, several uncertainties remained after the drilling of the appraisal wells. An integrated study has been launched, and involved all the disciplines related to subsurface modeling and field development, including HSE. The goal set by the asset management, was to to provide a realistic estimation of the range of reserves, and to propose different development plans, based on the knowledge of the asset, and taking into account the recommendations set by the local regulator (BSEE)
