ABSTRACT

An intensive geological study by the operator of the production Unit suggested that clean, unswept reef edge oil could exist in the reservoir. 3-D seismic data were acquired to delineate the reef edge to mitigate drilling risk associated with tapping into these potential reserves. Environmental concerns resulted in modifications to the original program design. Data quality exceeded expectations. Lithologic model-based seismic inversion was conducted to enhance confidence in the location of the reef edge and to investigate whether porosity predictions were possible. Log balancing, pattern recognition event picking, and isovelocity mapping of the reef and platform section were technological innovations required to address this mandate. Reef edge predictions and porosity predictions appeared trustworthy with resolution limits stretched to 1/6th of a wavelength. The seismic program proved to add value by mitigating drilling risk for two horizontal wells and one vertical well. The drilling results reaffirmed predictions, and unit production increased.
