The field is located in nearly 1,500 meters (4,900 ft) of water off the central Niger Delta. The operator of the field is Star Deep Water Limited, an affiliate of Chevron. Also involved in the field are Famfa Oil, an indigenous oil company owned by the Alakija Family of Lagos, Petrobras (Brazil), Statoil, and NNPC (the national oil company of Nigeria).
Most of the reserves are in lower and middle Miocene deepwater turbiditic sandstones and reserves are estimated at 900 MM barrels with upside to perhaps 1.5 B making it either the biggest or second biggest (to Bonga) deepwater field in Nigeria. Its crude oil quality is high API gravity in the high 30s (very flowable) and the crude is sweet (low sulfur). The trap is mainly anticlinal 4-way rollover but internally the doubly plunging anticline is cored by a small reverse fault and upwardly diapiric mobile shale or mud. The northwestern portion of the field is overthrusted at shallow levels.
Production began in 2008 at over 70,000 barrels per day (11,000 m3/d) with peak production estimated to be at approximately 250,000 bls/d. The Floating Production unit is the length of three football fields and cost over $US4 billion to build.
