Patent number: 8793111Abstract: A system for automatically optimizing a Field Development Plan (FDP) for an oil or gas field uses a fast analytic reservoir simulator to dynamically model oil or gas production from the entire reservoir over time in an accurate and rapid manner. An objective function defining a Figure of Merit (FoM) for candidate FDPs is maximized, using an optimization algorithm, to determine an optimized FDP in light of physical, engineering, operational, legal and engineering constraints. The objective function for the Figure of Merit, e.g., net present value (NPV) or total production for a given period of time, relies on a production forecast from the fast analytic reservoir simulator for the entire FDP.Type: GrantFiled: January 20, 2009Date of Patent: July 29, 2014Assignee: Schlumberger Technology CorporationInventors: Peter Gerhard Tilke, Vijaya Halabe, Raj Banerjee, Tarek M.
