in this research, a 2d laterally averaged model of hydrodynamics and water quality, ce-qual-w2, was applied to simulate water quality parameters in the ilam reservoir. the water quality of ilam reservoir was obtained between mesotrophic and eutrophic based on the measured data including chlorophyll a, total phosphorus and subsurface oxygen saturation. the ce-qual-w2 model was calibrated and ver...

In response to the urgent need for estimates of the oil and gas flow rate from the Macondo well MC252-1 blowout, we assembled a small team and carried out oil and gas flow simulations using the TOUGH2 codes over two weeks in mid-2010. The conceptual model included the oil reservoir and the well with a top boundary condition located at the bottom of the blowout preventer. We developed a fluid pr...

The trap efficiency of a shallow reservoir depends on the characteristics of the inflowing sediments and the retention time of the water in the reservoir, which in turn are controlled by the reservoir geometry. With the purpose of controlling the trapped and flushed sediments in shallow reservoirs, the effects of the geometry on sediment deposition and removal were investigated with systematic ...

a proper understanding of reservoir fluid phase behavior is the first crucial step in the development and production of an oil/gas field. this paper addresses the challenges and errors associated with the fluid sampling that may arise before, during and after the sampling operation. for this aim, dst and pvt data of exploration and production wells of a supergiant offshore gas condensate reserv...

We study the geodesic exponential maps corresponding to Sobolev type right-invariant (weak) Riemannian metrics μ (k ≥ 0) on the Virasoro group and show that for k ≥ 2, but not for k = 0, 1, each of them defines a smooth Fréchet chart of the identity. For k = 0 and k = 1 the corresponding geodesic flows are related to the Korteweg de Vries and Camassa Holm equations. In particular, the geodesic ...

~BSTRACT: A~ unsteady ~wo-dimens~onal (20) reservoir hydrodynamics and transport model is employed to slm~late contammate~ denSity cu~ents m the Shasta Reservoir after a chemical spill into the Sacramento River, Cahf. Three flow regimes (plungmg flow, underflow, and interflow) and their occurrence are captured by the laterally ~verag~d model. Transp~~ and mixing processes in the temperature-str...

In this paper, we show how a convex optimization methodology can be used to determine a static solution, representing exit-valve settings in a multi-node reservoir system. A tunedvalve algorithm is used to produce an optimal flow solution and is based on the objective of minimizing overall combined sewer overflow (CSO) reservoir spillage to receiving waters under a combination of dry and wet (s...

We have studied dynamo models with realistic assumptions for the induction effects and compare the resulting magnetic fields with observations. We make use of recent results of helioseismology to infer the differential rotation and adopt mixing length approach to get the form of the ct-effect, which is in general anisotropic. Dynamo models are computed numerically using an eigenva.lue method. F...

• Abstract: The tidal circulation in Paranagua Bay (Parana State, Southern Brazil) was studied based on the Princeton Ocean Model. The model domain covered the near shore region and the estuarine area, with about 1 km grid resolution in cross-shore and along-shore directions. Homogeneous and diagnostic distributions for temperature and salinity were used and 12 tidal constituents were considere...
