Increasing bandwidth with single sensor seismic data - the Lehib oilfield case study

From November 2006 through March 2007, Sirte Oil Company (SOC) successfully conducted the first application of the WesternGeco Q-Land single-sensor seismic system in Libya.  The goal of this project was to determine if single-sensor acquisition and processing techniques could enhance resolution and frequency content, allowing the construction of an accurate reservoir model over the Lehib oilfield. The survey delivered improved signal-to-noise ratio (S/N) and broader bandwidth over the target zone than had been achieved previously. Integration between acquisition geometry, source design, and processing parameters were key to the success of the project.
