Publication number: 20110310101Abstract: One or more computer-readable media include computer-executable instructions to instruct a computing system to access data that define a pillar grid where pillar nodes of the pillar grid define logical cells of a reservoir model, partition the pillar grid into subvolumes, build surfaces to define boundaries for each of the subvolumes where each of the surfaces includes polygons defined by surface nodes, generate a mesh of property nodes for each of the subvolumes where at least some of the property nodes include properties derived from properties of the reservoir model, and store data that define the subvolumes, the surfaces and the meshes. Other examples include a method of processing information for subsequent visual presentation with respect to a reservoir model and techniques for merging models. Various other apparatuses, systems, methods, etc., are also disclosed.Type: ApplicationFiled: June 22, 2010Publication date: December 22, 2011Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: David Michael Prange, Thibaut Klein, Hugues A.

Patent number: 8073800Abstract: The invention relates to a method of performing an oilfield operation of an oilfield having at least one well having a wellbore penetrating a subterranean formation for extracting fluid from an underground reservoir therein. The method steps include analyzing the oilfield operation to generate a decision tree comprising a first decision and a second decision, wherein a first outcome of the first decision dictates acquiring information relevant to the second decision, formulating a figure of merit of the oilfield operation according to the decision tree based on the information and uncertainties associated with the oilfield, determining a value of the figure of merit by modeling the oilfield operation using statistical sampling, and performing the oilfield operation upon making the first decision based on the value of the figure of merit.Type: GrantFiled: July 30, 2008Date of Patent: December 6, 2011Assignee: Schlumberger Technology CorporationInventors: Michael Prange, William J. Bailey, Benoit Couet, Hugues Djikpesse, Michael A. Elliott

Patent number: 8005658Abstract: A hybrid evolutionary algorithm (“HEA”) technique is described for automatically calculating well and drainage locations in a field. The technique includes planning a set of wells on a static reservoir model using an automated well planner tool that designs realistic wells that satisfy drilling and construction constraints. A subset of these locations is then selected based on dynamic flow simulation using a cost function that maximizes recovery or economic benefit. In particular, a large population of candidate targets, drain holes and trajectories is initially created using fast calculation analysis tools of cost and value, and as the workflow proceeds, the population size is reduced in each successive operation, thereby facilitating use of increasingly sophisticated calculation analysis tools for economic valuation of the reservoir while reducing overall time required to obtain the result. In the final operation, only a small number of full reservoir simulations are required for the most promising FDPs.Type: GrantFiled: May 31, 2007Date of Patent: August 23, 2011Assignee: Schlumberger Technology CorporationInventors: Peter Gerhard Tilke, William J.
