Schlumberger uses simulation in bidding and executing land seismic surveys

Schlumberger and its competitors use seismic surveying, the process of mapping subterranean rock formations with reflected sound waves, as an important first step in identification and recovery of oil and gas reserves. This complicated logistical operation commonly lasts two to six months, covers hundreds of square miles, employs scores of people, and utilizes a large variety of equipment. To win these jobs, Schlumberger participates in a closed bidding process organized by the oil companies. To succeed, it must quickly and accurately estimate the costs of seismic surveys. We developed a simulation tool to evaluate the impact of crew sizes (people and equipment), survey area, geographical region, and weather conditions on survey costs and durations. Schlumberger uses it to obtain and profit from a larger portion of the global seismic survey market. We demonstrated cost savings to clients of about $2 million on four surveys. Based on the number of surveys that Schlumberger conducts each year, it should save about $1.5 to $3 million each year.
