Patent number: 11263801Abstract: The present disclosure provides an automated interpretation workflow for smooth surface wrapping of an imaged volume. The methods use a volume attribute to classify data into regions corresponding to feature/uncertain/non-feature parts and use smoothing through the uncertain parts to connect the clear boundaries of the feature. Any volume attribute can be used as long as feature/uncertain/non-feature categories can be identified in terms of continuous or discontinuous threshold values or ranges. The workflow can be combined with interpretation of well-defined boundary parts to resolve uncertainty and can be used with both explicit single-z and implicit multi-z (level set) boundary representations.Type: GrantFiled: April 2, 2018Date of Patent: March 1, 2022Assignee: Schlumberger Technology CorporationInventors: Jarle Haukås, Aicha Bounaim, Oddgeir Gramstad

Patent number: 10545261Abstract: A method for modelling geomechanical effects in the subsurface by conditioning geomechanical model parameters to time-lapse observations. The model is driven by displacement boundary conditions derived from observed time-lapse travel time shift and time strain. The displacements at the boundaries of the model are extracted from time-lapse data, converted from travel time shift to depth shift and lateral shifts if necessary, and applied as displacement increments on the initial geomechanical model. Subsequently, increments of stresses and strains are calculated by the geomechanical simulator, and time-lapse related parameters in the interior of the model are compared with the time-lapse observations. This enables a comprehensive study of mismatch between simulations and observations that can be used to update material properties, faults, fractures and the rock strain-velocity change relationship (R factor).Type: GrantFiled: May 14, 2015Date of Patent: January 28, 2020Assignee: WESTERNGECO L.L.C.Inventors: Jarle Haukås, Jan Øystein Haavig Bakke, Michael Hermann Nickel, Lars Kristian Sønneland

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

Patent number: 9341728Abstract: A method of analysing seismic data from a geological volume is provided. The geological volume is divided into a plurality of voxels. For each voxel a respective neighbourhood is defined which includes that voxel and a predetermined arrangement of neighbouring voxels. For each voxel, the respective normal vectors of a seismic attribute vector field derived from the seismic data are calculated. For each voxel, a respective local structure tensor based on the normal vectors of the voxels of the respective neighbourhood is calculated. For each voxel, the value of an expression which includes one or more of the eigenvalues (?1, ?2, ?3) of the respective local structure tensor is calculated. The method can be used for seismic surveying, or to manage operation of or drilling of a subterranean well.Type: GrantFiled: July 29, 2013Date of Patent: May 17, 2016Assignee: WESTERNGECO L.L.C.Inventors: Aicha Bounaim, Oda Roaldsdotter Ravndal, Jarle Haukås

Publication number: 20140214328Abstract: A method of extracting a salt body from a geological volume is provided. A starting object is located within the geological volume. The starting object defines an initial salt body 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 salt body 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 salt body boundary over the successive iterations until a final form for the evolved salt body is achieved.Type: ApplicationFiled: January 28, 2013Publication date: July 31, 2014Applicant: WESTERNGECO L.L.C.Inventors: JARLE HAUKÅS, ODA ROALDSDOTTER RAVNDAL, LARS SØNNELAND
