Real-time seismie-while-drilling to reduce exploration risk

摘要

Exploration for hydrocarbons offshore Liberia, West Africa, first took place in the early 1970s on the shallow-water shelf area. This early phase of exploration ended in 1985, by which point six wells had indicated oil shows. Recent discoveries such as the billion-barrel Jubilee oilfield in the Cretaceous submarine fans of nearby Ghana, the Mercury and Venus fields in neighboring Sierra Leone, and discoveries in Cote d'lvoire have attracted several operators to begin new exploration drilling in deeper waters offshore Liberia. Operators have recently announced that their exploration activity has established a working hydrocarbon system in the liberian basin.
