  • Publication number: 20140163901
    Abstract: A population comparison system, method and a computer program product therefor. A stored list of population members, e.g., hydrocarbon reservoirs, characteristics and analogous members is partitioned into lists for each member. A weighting system automatically uses the partitions to determine a weight set (w*) for population member characteristic and a similarity function. The weighting system may include an objective model that iteratively, blindly identifies analogous members for each population member until the identified analogous members match the listed analogous members. An analogous member selector uses the weights set (w*) and similarity function to automatically select analogous listed members for each new population member.

  • Publication number: 20140136158
    Abstract: Assessing the impact of existing fractures and faults for reservoir management, in one aspect, may comprise employing a numerical mesh to generate a geomechanical model, the numerical mesh representing a geological reservoir and its surrounding regions, the numerical mesh comprising delimitation associated with regions and layering of geology without constraining the numerical mesh to explicitly represent a fault or fracture, initializing the geomechanical model to define initial stress-strain compatible with measured stress in well locations associated with the geological reservoir, generating a fluid-flow model employing the numerical mesh, solving for a coupled solution of the fluid-flow model and the geomechanical model, and employing the solved fluid-flow model and the geomechanical model to assess the impact.

  • Publication number: 20140136163
    Abstract: Coupling fluid-flow model and geomechanical model for integrated petroleum systems, in one aspect, may comprise analyzing historical data associated with a reservoir to determine one or more triggering events that trigger abrupt changes in the state of stress of the reservoir solid framework and in the pore pressure. One or more time steps are defined based on the determined triggering events. The fluid-flow model and the geomechanical model are coupled at the one or more defined time steps, e.g., one-way or two-way. Number of iterations may be calculated automatically for the two-way coupling to converge.

  • Patent number: 8679343
    Abstract: The present disclosure describes a method for the revaluation of aqueous waste streams generated in the propylene oxide and styrene co-production processes. In particular, it discloses a method of reducing the organic contaminant load from a highly contaminated aqueous stream and recovery from said stream of organic compounds that may be recirculated or used as fuel in the co-generation of energy, and which comprises: acidification of said aqueous stream with inorganic acid at a pH less than 4.5; separation of the two resulting phases at a temperature greater than 40° C.; washing of the organic phase produced in the previous step with an aqueous solution of excess acid and separation of the two resulting phases.
