ExxonMobil Upstream Research Company - Houston TX

International Classification:

G06G 7/48

US Classification:

703 10

Abstract:

A method and apparatus for segmenting geobodies extracted from three-dimensional geophysical survey data volumes. In one embodiment, the invention involves (a) obtaining a plurality of data elements, respectively corresponding to three-dimensional locations in a subsurface region, and generating a data volume consisting of discrete cells from the plurality of data elements (); (b) identifying an initial geobody corresponding to a potential hydrocarbon reservoir within the data volume by grouping cells in the data volume according to a selected connectivity criterion (); (c) selecting a rule () that characterizes stratigraphically reasonable geobodies (e. g. they cannot vertically overlap); and (d) in response to a determination that the initial geobody does not conform to the rule, segmenting the initial geobody into a plurality of fundamental geobodies via processing the data elements with an automated segmentation routine, wherein the fundamental geobodies each conform to the rule ().

International Classification:

G06G 7/48
E21B 43/00

US Classification:

703 10, 166369

Abstract:

The present application describes a method and system associated with the production of hydrocarbons. In the method, fluid travel time models are constructed from a reservoir model. Then, reservoir connectivity measures are calculated from the fluid travel time models and analyzed to determine a location for at least one well. Based on the analysis, one or more wells may be drilled and hydrocarbons produced.

International Classification:

G06G 7/48

US Classification:

703 10

Abstract:

A method for modeling a dynamic system (e.g., geological system) comprises: constructing an input parameter space for a model of the geological system, the input parameter space including more than three dimensions, and the model associated with response data, representing the input parameter space visually with three or fewer dimensions, reducing the input parameter space by conditioning the parameter space using at least a subset of the response data, and updating the representation of the input parameter space to visually represent the reduction of the parameter space.
