Europa Subsea Development
Europa is located in Mississippi Canyon Block 934, 935 and 890 in the Gulf of Mexico about 140 miles southeast of New Orleans in approximately 3,900 feet of water.
The leases were acquired in OCS Lease Sales 98 and 113 in May 1985 and March 1988, respectively. Shell Offshore Inc. is the operator and has a 33.67% interest in the project. BP Exploration and Production Inc. has a 33.33% interest, ENI (Agip) has a 32% interest and Conoco has a 1% interest.Exploration and Discovery
The discovery well was drilled in 1994 on Mississippi Canyon Block 935 by BP using the Ocean America semisubmersible. Two sidetracks and one appraisal well were subsequently drilled.
The target reserves are in multiple Upper Miocene sands at depths ranging from approximately 16,000 to 19,000 feet subsea.
The average net thickness is approximately 125 feet. The reserves are primarily oil. API gravity is about 24 degrees; sulfur content is about 3% by weight.
Shell announced in March 1998 the partners’ plans to develop Europa utilizing a subsea system located on Mississippi Canyon Block 935, capable of accommodating eight wells, and tied back 20 miles to the Mars TLP on Mississippi Canyon Block 807 in 2,940 feet of water.
The first phase of development consisted of 4 wells. Additional wells were drilled in subsequent phases, as needed, to maintain flow rate and optimize ultimate recovery from the field. Currently, there are 6 wells drilled and completed in the field.
Shell plans to drill a new producer in 2011 and possibly two further wells over the coming 5 years.
