Schlumberger

Venezuela Reservoir Optimization Conference


Held in Caracas, this conference was the first organized for Venezuela since 1980. With a theme of "Optimizing Well Production and Reservoir Understanding from Well Data," its goal was to show how technology had solved some of this country's exploration and development problems. Examples from Venezuela focus on integration of services, both in application and organization. (362 pages)
