Abstract: The disclosed embodiments include a method, apparatus, and computer program product for generating multiple correlated meshes around complex and discrete fractures for the purpose of reservoir simulation. In an initial two-stage process, a 2.5-dimensional mesher algorithm, may be used in conjunction with an extended anisotropic geometry-adaptive refinement algorithm to produce, from a structured grid Earth Model, a refined reservoir model. Fractures may be modeled as a volumetric mesh that is independent of the refined reservoir model. Thereafter, the two independent, overlapping meshes are combined by forming matrix-matrix, fracture-fracture, and matrix-fracture connections to form a single model to allow rapid simulation of an extremely complex fracture network with sufficiently accurate results.

Abstract: A system and method inserts fracture networks into an existing Earth Model that exists as a structured grid and physical property values. The fracture network is in the form of a surface mesh (manifold or non-manifold) in a three-dimensional (“3D”) space. The structured grid of the Earth Model is then anisotropically refined to resolve the fractures and to provide appropriate cell grading in the near-fracture region. The generated Earth Model may be utilized in a variety of applications, including for example, a reservoir simulation.

Abstract: A rotatable engine holding assembly for permitting rotation of an engine while the engine is being held above a support surface. The rotatable engine holding assembly includes a support frame having an attachment assembly couplable to an engine block to hold the engine. The assembly includes a rotatable axle coupling the attachment assembly to the support frame to permit rotation of the engine while the engine is being held.
