Abstract: A method for forecasting performance for and characterizing the properties of a multilayer low permeability gas reservoir. The method includes a coupled well/reservoir predictive model that accounts for pressure drop between layers, allowing accurate, rigorous, and rapid forecasting of reservoir performance. The method provides estimates of individual layer properties such as in-situ permeability, skin factor, fracture half-length, fracture conductivity, drainage area, etc. by simultaneously history matching production data and production log data using the coupled well/reservoir predictive model.
Abstract: A method for generating and evaluating a table model for circuit simulation in N dimensions employing mathematical expressions for modeling a device. The table model uses an unstructured N-dimensional grid for approximating the expressions.
Abstract: Graphic displays or audio sound representations of numerical solutions of physics problems modeled by complicated, computationally complex mathematics are generated by Type I and Type II quantum computers, which employs a plurality of classically interconnected nodes each consisting of relatively few qubits, or classical computers emulating Type I and Type II quantum computers. This is done by setting the boundary conditions so that conservation is maintained within a high precision and performing multi-demensional computations as a series of single dimensional computations employing pseudo-random number generators on a classical computer to simulate the stochastic nature of the quantum process. On a quantum computer randomness is supplied the quantum process direction.

Abstract: Developing decision-making skills of a user through practice in a simulated environment comprises defining a simulated situation to be influenced by the user including a set of objects that are represented by an attribute-characteristic representation, presenting information concerning a current state of the simulation, obtaining decisions from the user that at least partially determine object designs to be evaluated, evaluating an object design using a value function having multiple optima, updating the simulation with the results from the evaluation, and permitting continued practice by selectively repeating several of these steps. A system executes simulation software that simulates such a situation on a processor, and includes evaluation software for selecting and evaluating design objects by applying a value function having multiple optima. At least one terminal and communication links are provided for information transfer and implementation of the simulated situation.
