Patent number: 10481297Abstract: A method of determining a migration pathway of a subterranean fluid through a geological volume is provided. The starting object is located within the geological volume. The starting object defines an initial fluid boundary. Data points are distributed through the geological volume. The data points are associated with values of one or more geological attributes. The method includes the steps of: defining an expression which determines a change in position of the fluid boundary at the data points over an iteration based on the values of the one or more attributes; and applying the expression at the data points for successive iterations to evolve the fluid boundary over the successive iterations. The migration pathway of the subterranean fluid through the geological volume can then be determined from the evolution of the fluid boundary.Type: GrantFiled: January 28, 2013Date of Patent: November 19, 2019Assignee: WESTERNGECO L.L.C.Inventors: Oda Roaldsdotter Ravndal, Jarle Haukås, Bjørn Harald Fotland, Lars Sønneland

Publication number: 20160146960Abstract: A method of analysing a subsurface region. 4D seismic data is received from a subterranean reservoir that is being seismically evaluated. A first set of values representing a first attribute at a plurality of first coordinates within the subsurface region is obtained from the 4D seismic data. A second set of values representing a second attribute at a plurality of second coordinates within the subsurface region is also obtained from the 4D seismic data, wherein each of the plurality of second coordinates corresponds to a respective first coordinate. For each first coordinate, a measure of dependence is calculated and the calculated measure of dependence is used to detect changes in the reservoir over time.Type: ApplicationFiled: November 21, 2014Publication date: May 26, 2016Inventors: Dirk Gunnar Steckhan, Oddgeir Gramstad, Michael Nickel, Lars Sonneland

Patent number: 8571799Abstract: A methodology improves sampling and characterization of heterogeneous, unconventional hydrocarbon-bearing regions. The methodology is designed to integrate consistently across measurements and scales. Additionally, the methodology involves characterizing various scales, such as regional-scale heterogeneity, wellbore-scale heterogeneity, core-scale heterogeneity, sample-scale, and pore-scale heterogeneity. The results are integrated across the multiple scales based on results obtained from the characterization of the scales. The methodology further comprises determining data propagation across the multiple scales in a hydrocarbon-bearing region.Type: GrantFiled: June 10, 2011Date of Patent: October 29, 2013Assignee: Schlumberger Technology CorporationInventors: Roberto Suarez-Rivera, David Handwerger, Lars Sonneland, Samuel Fluckiger, Mary Milner, Douglas Ekart
