摘要： A multi-scale finite volume method for simulating a fine-scale geological model of subsurface reservoir is disclosed. The method includes providing a fine-scale geological model of a subsurface reservoir associated with a fine-scale grid, a coarse-scale grid, and a dual coarse-scale grid. A coarse-scale operator is constructed based on internal cells, edge cells, and node cells on the fine-scale grid that are defined by the dual coarse-scale grid. Pressure in the dual coarse-scale cells is computed using the coarse-scale operator. Pressure in the primary coarse-scale cells is computed using the computed pressure in the dual coarse-scale cells. A display is produced using the computed pressure in the primary coarse-scale cells. An iterative scheme can be applied such that the computed pressure in the primary coarse-scale cells converges to the fine-scale pressure solution and mass balance is maintained on the coarse-scale.

摘要： An apparatus and method for collecting data acquired during a seismic survey are disclosed. The apparatus is a seismic survey system, comprising a plurality of data sources, a plurality of cells, and a plurality of independent pathways. The data sources are positioned about an area to be surveyed, each data source being associated with a transmitter capable of transmitting data. The cells each contain a portion of the data sources and their associated transmitters. One of the transmitters within each cell also serves as a gateway for receiving data transmitted from the other data source transmitters within the cell. The independent pathways each contain a portion of the gateways whereby data may be transmitted along each pathway via the gateways and associated transmitters in that pathway. The method is a method for conducting a seismic survey. The method comprises positioning a plurality of seismic data sources about an area to be surveyed; defining a plurality of cells such that each cell contains a portion of the seismic data sources; defining one of the seismic data sources within each cell to also serve as a gateway; defining a plurality of independent pathways such that each pathway contains a portion of the gateways; within each respective cell, transmitting seismic data from the seismic data sources to the gateway; and, within each pathway, transmitting the seismic data from one gateway to another to reach a central location.

摘要： Methods and computer readable media for performing a compositional reservoir simulation of a subterranean hydrocarbon-bearing reservoir is provided (500). Reduced variables for flash computations are utilized with a methodology of conditional stability testing for achieving optimal efficiency of phase behavior computations in a compositional reservoir simulator (510). A least abundant phase is selected as primary variables for a primary phase and a secondary phase is selected for a more abundant phase to ensure stability by not dividing by a value near zero due to the selection of the primary phase as being associated with phase which is the least abundant. A bounded interval may be used to limit solution changes in reduced variable algorithms to achieve great stability of algorithms. Stability test may be performed During flash computation using reduced variables by employing Direct residual from based on the definition of the reduced variables and the tangent-plane distance condition.
