  • Patent number: 8352227
    Abstract: A method for performing operations of an oilfield is described. The method involves selectively coupling oilfield simulators according to a predefined configuration, each oilfield simulator modeling at least a portion of the oilfield, a first oilfield simulator receives an oilfield control parameter as an input, identifying an uncertainty parameter associated with probable values each corresponding to a weighted probability, a second oilfield simulator receives the uncertainty parameter as an input, modeling the operations of the oilfield to generate an estimated performance by selectively communicating between the oilfield simulators, the operations of the oilfield are modeled with a predetermined value of the oilfield control parameter and at least one of the probable values of the uncertainty parameter; and identifying an optimal value of the oilfield control parameter based on the estimated performance.

  • Patent number: 8332194
    Abstract: A method of performing production operations of an oilfield, including obtaining a sample of separator discharge fluid from a separator, performing gas chromatography on the separator discharge fluid to obtain gas molar composition, performing oil characterization on the separator discharge fluid to obtain oil density and oil molecular weight, performing a simulation of the separator based on the gas molar composition, the oil density, the oil molecular weight, and a gas oil ratio (GOR) of the separator discharge fluid to obtain a simulated composition of separator inlet fluid, and presenting the simulated composition of separator inlet fluid, when the difference between the actual composition of separator outlet fluid and the simulated composition of separator outlet fluid is less than a threshold value.

  • Patent number: 8306801
    Abstract: One or more computer-readable media include computer-executable instructions to instruct a computing system to receive simulation results for future behavior of a reservoir that includes a material production well and a fluid injection site; define a virtual sensor as being located between the material production well and the fluid injection site; determine fluid saturation at the virtual sensor based at least in part on the simulation results; and issue a notification if the fluid saturation at the virtual sensor exceeds a fluid saturation limit. Various other apparatuses, systems, methods, etc., are also disclosed.

  • Patent number: 8301383
    Abstract: A method for constructing elastoplastic property correlations in multicomponent particulate systems. The method includes obtaining parameters from geophysical data of a sediment-hydrate system, where the parameters include shyd and pc, and where shyd is a hydrate saturation and pc is a confining pressure. The method further includes determining a Young's modulus (E) of the sediment-hydrate system using the parameters and a correlation, where the correlation is E p c = 90.58 + 78.90 ? 0.5831 + 800.4 ? s hyd 1.371 ? 1.022 , and where ?=pc/c and c is a scaling variable with dimensions of pressure. The method further includes adjusting a field operation based on the Young's modulus of the sediment-hydrate system.

  • Patent number: 8271243
    Abstract: The invention provides a system and method for integrating petroleum system and geomechanical computer models for use in oil and gas exploration. In one embodiment, the invention provides a petroleum system model capable of analyzing data relating to a subterranean formation and calculating the geometry and geochemistry of each layer of the formation through geologic time. The present invention also provides a geomechanical model in communication with the petroleum system model such that information concerning each layer of the subterranean formation may be shared and cross-referenced as an iterative operation prior to the analysis of subsequent layers. At each step of the iterative operation, results are calculated, validated, and cross-referenced in order to produce improved reliability estimates of petroleum charge and mechanical seal integrity for the subterranean formation.
