Abstract: Systems, methods, and computer-readable media for determining the production rate of oil produced from each of a plurality of oil-bearing geological layers in an oil field. In some embodiments, the method comprises allocating injected fluid into each layer of a plurality of oil-bearing geological layers to a plurality of paths from injection sites of injection wells to production wells in each layer by balancing the mass of fluid injected into and the total fluid recovered from each oil-bearing geological layer. In some embodiments, the method comprises calculating estimated geological properties for each path in the plurality of paths to match total oil and injection fluid recovered at each production well in the plurality of production wells. In some embodiments, the method comprises using the estimated geological properties, calculating an oil production rate for each path between an injector well and a production well in a geological layer.

Abstract: A system and method for characterizing subsurface hydrocarbon reservoirs, such as through fault modeling in low order continuous scale simulation of real world subsurface hydrocarbon reservoirs having discontinuities and improving an accuracy and speed of the characterizations.

Abstract: Systems and methods are disclosed for an automatic fluid composition sensor. A fluid composition sensor includes a plurality of detection elements positioned along a length of a sample chamber having a number of material interfaces, the fluid composition sensor detecting location(s) of the interface(s) and/or a composition of one or more of the materials within the chamber. A fluid level sensor generates one or more pulses and measures a time delay between a transmission of the pulses from a source and a reception of the reflected pulses from a gas/oil interface to estimate a position of the oil/gas interface and thus a height of the oil in an oil well.
