Patent number: 11500123Abstract: Hybrid 3D geocellular grids are generated to represent a subset of a natural fracture network (“NFN”) directly in the simulation, while the remainder of the NFN is approximated by a multi-continuum formulation. The resulting output is a 3D geocellular grid that possesses a higher level of mesh resolution in those areas surrounding the first fracture subsets, and lower mesh resolution in the areas of the second fracture subset.Type: GrantFiled: February 29, 2016Date of Patent: November 15, 2022Assignee: Landmark Graphics CorporationInventors: Amit Kumar, Michael Loyd Brewer, Dominic Camilleri, Steven Ward

Patent number: 10564317Abstract: One example herein involves a method that includes identifying, based on a received reservoir specification: a set fractures including 2.5 dimensional (2.5D)-permitting fractures; and other fractures. The method further includes generating an intermediate reservoir model including an extrusion mesh which models the 2.5D-permitting fractures in a three-dimensional (3D) space. In response to determining that cells in the mesh should be refined in a direction within the 3D space, the method anisotropically refines cells in the mesh corresponding to the other fractures. The method also includes resolving a fracture network within the intermediate reservoir model using the refined cells and then generating a reservoir earth model using the fracture network.Type: GrantFiled: November 12, 2014Date of Patent: February 18, 2020Assignee: Halliburton Energy Services, Inc.Inventors: Michael Loyd Brewer, Steven Bryan Ward, Gerrick Bivins

Patent number: 10436939Abstract: The disclosed embodiments include a method, apparatus, and computer program product for generating hybrid computational meshes around complex and discrete fractures for the purpose of reservoir simulation. For example, one disclosed embodiment includes a method that comprises receiving a set of 3D fracture surfaces with geometry that has been discretized in a 2D manifold by a collection of polygons. The method defines a family of non-intersecting 2D slicing surfaces for slicing the set of 3D fracture surfaces. The method then uses the intersection of the 2D slicing surface with the 2D manifolds defining the fracture surfaces to create a set of 2D fractures on each slicing surface. Following a series of steps, the method generates three-dimensional shells connecting a set of stadia corresponding to each fracture on each 2D slicing surface to a corresponding set of stadia on a neighboring 2D slicing surface for creating a three-dimensional model.Type: GrantFiled: July 2, 2013Date of Patent: October 8, 2019Assignee: Landmark Graphics CorporationInventors: Steven Bryan Ward, Michael Loyd Brewer

Patent number: 10422925Abstract: The disclosed embodiments include a method, apparatus, and computer program product for generating hybrid computational meshes around complex and discrete fractures for the purpose of reservoir simulation. For example, one embodiment is a computer-implemented method for modeling three-dimensional (3D) geological fractures. The method includes the steps of receiving a set of fractures with geometry that has been discretized in a two-dimensional plane by a collection of line segments. The method generates closed loops around all the line segments associated with a fracture using a set of stadia and further generates shape elements within the closed loops. A constrained mesh around the closed loops of the set of fracture is generated to fill in a remainder space of the two-dimensional plane. The cell elements in the two-dimensional plane can then be extruded in a third dimension to form a three-dimensional model usable for performing reservoir simulations.Type: GrantFiled: July 2, 2013Date of Patent: September 24, 2019Assignee: Landmark Graphics CorporationInventors: Steven Bryan Ward, Michael Loyd Brewer

Publication number: 20170299770Abstract: Systems and methods are provided for creating reservoir meshes using extended anisotropic, geometry-adaptive refinement of polyhedral. In one example, a method includes identifying, based on a received reservoir specification: a set fractures including 2.5 dimensional (2.5D)-permitting fractures; and other fractures. The method further includes generating an intermediate reservoir model including an extrusion mesh which models the 2.5D-permitting fractures in a three-dimensional (3D) space. In response to determining that cells in the mesh should be refined in a direction within the 3D space, the method anisotropically refines cells in the mesh corresponding to the other fractures. The method also includes resolving a fracture network within the intermediate reservoir model using the refined cells and then generating a reservoir earth model using the fracture network.Type: ApplicationFiled: November 12, 2014Publication date: October 19, 2017Inventors: Michael Loyd Brewer, Steven Bryan Ward, Gerrick Bivins

Patent number: 9715762Abstract: The disclosed embodiments include a method, apparatus, and computer program product for modeling three dimensional objects, such as, but not limited to, fractures, for the purpose of reservoir simulation. For example, one disclosed embodiment includes a method that receives a set of 3D fractures with geometry that has been discretized by 2D surfaces by a collection of polygonal facets, generates a set of 3D stadia at specified radii around each facet in the collection of polygonal facet, generates closed 3D stadia surfaces around intersecting facets, discretizes all 3D stadia surfaces using various shape cells, generates 3D cells within each of the closed 3D stadia surfaces, and assigns each cell reservoir properties suitable for a numeric simulation program, such as, but not limited to, Nexus® Reservoir Simulation Software.Type: GrantFiled: July 2, 2013Date of Patent: July 25, 2017Assignee: LANDMARK GRAPHICS CORPORATIONInventors: Steven Bryan Ward, Michael Loyd Brewer

Publication number: 20070170709Abstract: An apparatus (10) for helping to protect an occupant of a vehicle includes a housing (20) including a vent opening (70). An air bag (14) is inflatable to deploy away from the housing (20). An inflation fluid source (26) provides inflation fluid for inflating the air bag (14). A vent member (80) has a closed condition blocking inflation fluid flow through the vent opening (70) and an open condition permitting inflation fluid flow through the vent opening. A first tether (114) is configured to release the vent member (80) for movement from the closed condition when the air bag (14) has deployed a first distance away from the housing (20). A second tether (140) is configured to place the vent member (80) in the closed condition when the air bag (14) has deployed a second distance away from the housing (20), the second distance being farther away from the housing than the first distance.Type: ApplicationFiled: January 20, 2006Publication date: July 26, 2007Inventors: William Braun, Ken Taggart, Douglas Gould, Kurt Fischer, Alex Meduvsky, Michael Loyd
