Simulations for Hydraulic Fracturing Treatments and Methods of Fracturing Naturally Fractured Formation
A hydraulic fracture design model that simulates the complex physical process of fracture propagation in the earth driven by the injected fluid through a wellbore. An objective in the model is to adhere with the laws of physics governing the surface deformation of the created fracture subjected to the fluid pressure, the fluid flow in the gap formed by the opposing fracture surfaces, the propagation of the fracture front, the transport of the proppant in the fracture carried by the fluid, and the leakoff of the fracturing fluid into the permeable rock. The models used in accordance with methods of the invention are typically based on the assumptions and the mathematical equations for the conventional 2D or P3D models, and further take into account the network of jointed fracture segments. For each fracture segment, the mathematical equations governing the fracture deformation and fluid flow apply. For each time step, the model predicts the incremental growth of the branch tips and the pressure and flow rate distribution in the system by solving the governing equations and satisfying the boundary conditions at the fracture tips, wellbore and connected branch joints. An iterative technique is used to obtain the solution of this highly nonlinear and complex problem.

The present invention is a method and apparatus for automatically generating an optimal configuration of a product having a complex design, using logic implemented on digital computer processing system. A general configuration for the product will be broken down into a hierarchy of subdesigns by a designer of an artifact type, such as a bus. A particular instance of the product type must satisfy a set of external parametric constraints specified by a user. These constraints may take the form of a range of values for some performance characteristic of the product. Constraints may also be imposed for other reasons, such as governmental regulations or business requirements. The hierarchical decomposition facilitates the solution of highly complex problems. Criteria for a best solution may be specified for a given subdesign, for a collection of subdesigns, or globally. The tentative selection of a particular subdesign may impose internally generated parametric constraints upon a subsequent subdesign solution. If no acceptable solution is found for a given subdesign, the candidate overall configuration is rolled back to the most complete viable partial collection of subdesigns. The method transforms the constraints into a concrete design. The method will ordinarily be executed on a digital computer, and the instructions to program the computer will be stored on tangible digital media.

Modular, hierarchically organized artificial intelligence entity
InactiveUS6738753B1Use intelligenceIncrease profitGenetic modelsDigital computer detailsModularityData mining
A modular artificial intelligence learning entity (a "golem") which is replicated many times to form a super-entity that shows intelligent behavior transcending that of its individual constituents. Within the group of golems, individual golems may occupy roles, and are role differentiated, in that structurally identical entities perform different functions and exhibit different behavior depending on their personas and the learning they have completed as driven by other entities. The group of golems is hierarchically organized, in the sense that 'superior' entities issue policies to 'subordinate' entities. In addition to responding to 'sense' input from its environment, the golem responds to policy requirements set by other entities, including its superiors, and in turn sets policy requirements for its subordinates. Actions of the golem are measured for successful compliance with that golem's policies by its superior, who directs the golem's learning process. The super-entity thus gains intelligence through the policy reinforcement occurring in each superior-subordinate relationship. This scheme is well adapted to working over a network with logically separated but communicating golems. Its flexibility allows its application both to single complex problems and to repetitively occurring simple problems. Opportunities for its use arise in operating environments, in simulation and gaming, and in research.
