Abstract: Described herein are various embodiments of computer-implemented methods, computing systems, and program products for analyzing a flood operation on a hydrocarbon reservoir. For example, an embodiment of a computer implemented method of determining a value of injected fluid includes, for a first injection well of the hydrocarbon reservoir: receiving injection rate data for the first injection well and production rate data for at least one production well communicating with the injection well, running capacitance resistance modeling using the received data to generate an interwell connectivity for each injection well and production well pair, determining a value of injected fluid for each injection well and production well pair using the generated interwell connectivity for the well pair and an oil-cut value for the production well of the pair, and aggregating the generated values of injected fluid per pair to determine a value of injected fluid for the first injection well.

Abstract: Depth-averaged flow simulation systems and methods provided herein employ parameterized templates for dynamical depth profiling for at least one step of a simulation. In one illustrative computer-based embodiment, the simulation method includes, for each map point at one given time step: determining a flow template and a sediment concentration template based on depth-averaged flow velocity and depth-averaged sediment concentrations of different classes of grain size for that map point; employing the templates to construct a vertically-distributed flow velocity profile and vertically-distributed sediment concentration profiles for associated classes of grain size for that map point, thereby obtaining 3D flow velocity and 3D sediment concentration fields; using the 3D fields to calculate fluid and sediment fluxes; updating the flow velocity and sediment concentration profiles based on the divergence of the fluxes; integrating the profiles to compute updated depth-averaged flow velocity and sediment concentrations and center of gravity; and solving the depth-averaged flow equations for the next time step.

Abstract: Disclosed are processes for removing carbon steel components of a subsea oilfield facility in a subsea environment by accelerating the corrosion of the carbon steel components in the surrounding seawater, by a passive and/or active impressed current method. In the passive method, the facility is connected to a cathodic metal of greater electrical potential, such as copper. In order to cause the maximum and uniform corrosion, it is preferred that a wire of the chosen cathodic metal be extended along the facility and through pipelines. In the active impressed current method, an external DC electrical supply is used to apply an electrical potential difference between the steel components of the facility and the cathodic metal.

Abstract: Methods and systems for controlling the timing of a fluid driven positive displacement pump (FDPDP) are disclosed using pump inlet pressure, flow rate and time domain control. Pressure is thus controlled at various flow rates of fluids to be pumped in subsea environments. The FDPDP includes a plurality of pressure vessels connected by piping, each vessel having two chambers. One chamber is connected to a source of fluid to be pumped and the other chamber is connected to a source of driving fluid. The methods synchronize pumping chambers that have no mechanical means to control timing between each pumping chamber. The control methods described utilize algorithms which receive feedback from the pumping system to control the pumping sequence and adapt to any parameter changes to maintain a constant range of desired pressure.

Abstract: Porous media containing undesired substances, e.g., perfluoroalkylated substances, are treated by mixing the porous media with a solid fuel comprising organic material. The mixture is heated to 200° C. to 400° C. to initiate smoldering combustion and an oxidizer gas is forced through the heated mixture such that the smoldering combustion is self-sustaining until the mixture reaches a PFAS destructive temperature and the perfluoroalkylated substances are thermally destroyed. A system is provided for conducting the treatment. The system includes a source of wax, wood chips, sawdust, tire scraps, waste rubber compounds, coal, granular activated carbon, solid fat, and combinations thereof as solid fuel. A mixer is provided for mixing the porous media with the solid fuel. An ignition system including static heating elements and a gas blower are provided for forcing heated oxidizer gas through the mixture such that self-sustaining smoldering combustion of the mixture is initiated and sustained.
