  • Publication number: 20150219793
    Abstract: A method of simulating a hydrocarbon reservoir is disclosed. A process-based model is generated that mimics a depositional process of the reservoir. The process-based model is analyzed to extract statistics of geometries of a body that forms part of the reservoir, and depositional rules of the body. An object-based modeling method is applied to construct multiple unconditional geologic models of the body using the statistics and the depositional rules. Training images are constructed using the multiple unconditional geologic models. Well data and gross thickness data are assigned into a simulation grid. A single multiple-point geostatistical simulation is performed using the training images. A three-dimensional (3D) reservoir model is constructed using results of the multiple-point geostatistical simulation.

  • Publication number: 20150184272
    Abstract: Systems and methods of a low cost, high strength titanium alloy are disclosed. According to illustrative implementations, the weight percent of the alloy composition may be: Fe content 3%˜7%, Al content 3%˜5%, C content 0.01%˜0.02%, with the balance being Ti and unavoidable impurities. Industrial pure iron, carbon steel, and industrial pure aluminum etc. may be used as the raw materials. In one exemplary method, the raw materials are mixed before being pressed to a block. The block may be double-melted to an alloy cast ingot, forged by a conventional titanium alloy forging process, and subsequently undergo a solid solution treatment of (820° C.˜950° C.)/1 h+water quenching, and an ageing treatment of (450° C.˜550° C.)/4 h+air cooling, wherein the mechanical properties of the alloy are that ?b=1000˜1250 MPa, ?=5%˜12%.
