Abstract
The discovery well for the Nembe Creek field in the coastal swamp of the Niger delta was drilled in 1973. Average recoverable reserves have risen to over 600 million bbl after the drilling of 30 wells. Nearly one-third of the wells drilled have been proposed on the basis of direct reflection seismic support, principally in the form of seismic structure mapping and cross sections. In addition, lateral predictions on the basis of true amplitude impedance data have been made for two appraisal wells. The timely acquisition and interpretation of sufficient seismic lines in an area of complex structure, but good reflection quality, have permitted the drilling of long step-out appraisal wells, leading to early delineation of field limit and rapid growth of proved reserves.
