Kosmos Energy and BP have completed the drilling of the Hippocampe-1 exploration well. The Hippocampe-1, located on Block C-8 offshore Mauritania, was drilled to a total depth of 5,500 meters in approximately 2,600 meters of water.
The well was designed to test Lower Cenomanian and Albian reservoirs charged from the deeper Valanginian – Neocomian source. During drilling well-developed reservoirs were encountered in both exploration targets but these proved to be water bearing. The well will now be plugged and abandoned.
According to Kosmos, it is believed that this prospect failed due to a lack of charge access in this part of the play fairway.
The rig used to drill the well, the Ensco DS 12 drillship, is now mobilizing to Block C-12 offshore Mauritania to test the independent Lamantin oil prospect. The prospect comprises Campanian age reservoirs charged from the shallow, immediately underlying, oil prone, oil mature Albian and Cenomanian–Turonian source rocks.
Andrew G. Inglis, chairman and CEO, said: “Following on from our Yaakar discovery earlier this year, Hippocampe-1 is the second of four tests of independent prospects located in the outboard basin floor fan fairways in our Mauritania and Senegal acreage. Although the well did not encounter oil or gas, it has, together with Yaakar, confirmed the presence of quality cretaceous reservoir in the outboard basin floor fans, which contain multiple leads and prospects, more than 200 km from the north to south through our blocks. We are still in the early stages of opening this newly emerging basin and our forward drilling program remains unchanged given the independent nature of the prospect tests, in particular with regard to charge.”
