Patent number: 10656295Abstract: A method for generating one or more subsurface stress models. The method may include receiving seismic data. A plurality of first geomechanical property models may be generated based at least partially on the seismic data. A second geomechanical property model may be generated based at least partially on the seismic data. The second geomechanical property model may have a lower resolution than the first geomechanical property models. A stress model, a strain model, or a combination thereof may be generated based on the second geomechanical property model. One or more subsurface stress models may be generated based on the stress model, the strain model, or the combination thereof and the first geomechanical property models.Type: GrantFiled: October 17, 2014Date of Patent: May 19, 2020Assignee: Schlumberger Technology CorporationInventors: Adrian Rodriguez-Herrera, Xavier Garcia-Teijeiro, Jorg V. Herwanger, Nikolaos Constantinos Koutsabeloulis, Tone Trudeng, Jalal Khazanehdari

Patent number: 8762118Abstract: A method for modeling hydraulic fractures of a well. The method includes receiving a reservoir model that describes petrophysical properties of a subsurface of the earth near a reservoir. The method then receives one or more mechanical properties of the reservoir and generating a geomechanical model of the reservoir based on the reservoir model and the mechanical properties. After generating the geomechanical model of the reservoir, the method generates a three dimensional (3D) representation of the hydraulic fractures based on the geomechanical model and the reservoir model.Type: GrantFiled: October 17, 2011Date of Patent: June 24, 2014Assignee: Schlumberger Technology CorporationInventors: Gaisoni Nasreldin, Nikolaos Constantinos Koutsabeloulis, Vincenzo De Gennaro, Stephen Alexander Hope

Patent number: 8515720Abstract: A method for fracture modeling of a field. The method includes receiving, using a central processing unit (CPU), a structural model of the field, the structural model comprising field data, restoring each of a plurality of geological layers from the structural model to create a plurality of boundary conditions, iteratively forward modeling each of the plurality of geological layers, defined by one of the plurality of boundary conditions, using geomechanical properties by and redetermining the fractures resulting from the internal stress and the internal strain for each previously processed geological layer of the plurality of geological layers using the geomechanical properties, when each of the plurality of layers is forward modeled, generating, using the CPU and geostatistical modeling, a fracture model with the fractures resulting from the internal stress and the internal strain of the plurality of layers, and presenting the fracture model for use in planning a field operation.Type: GrantFiled: April 6, 2010Date of Patent: August 20, 2013Assignee: Schlumberger Technology CorporationInventors: Nikolaos Constantinos Koutsabeloulis, Gui Fen Xi, Qinglai Ni

Patent number: 8271243Abstract: The invention provides a system and method for integrating petroleum system and geomechanical computer models for use in oil and gas exploration. In one embodiment, the invention provides a petroleum system model capable of analyzing data relating to a subterranean formation and calculating the geometry and geochemistry of each layer of the formation through geologic time. The present invention also provides a geomechanical model in communication with the petroleum system model such that information concerning each layer of the subterranean formation may be shared and cross-referenced as an iterative operation prior to the analysis of subsequent layers. At each step of the iterative operation, results are calculated, validated, and cross-referenced in order to produce improved reliability estimates of petroleum charge and mechanical seal integrity for the subterranean formation.Type: GrantFiled: January 26, 2010Date of Patent: September 18, 2012Assignee: Schlumberger Technology CorporationInventors: Nikolaos Constantinos Koutsabeloulis, Stephen Alexander Hope, John Fuller, Melissa Suman, Thomas Hantschel, Michael De Lind Van Wijngaarden, Ian David Bryant, Rodney Laver
