摘要： A hydrocarbon shale reservoir simulation system and method represented by a model having at least four different types of porosity nodes is described. The method includes the computer-implemented steps of characterizing porosity nodes within the model as one of natural fracture pore systems, matrix pore systems, induced fracture pore systems or vug pore systems. Following characterization, transfer terms between nodes are identified. Transfer terms may include transfer terms between vug nodes, matrix nodes, natural fracture nodes and induced fracture nodes. Once transfer terms have been assigned, the linear system for the model can be solved utilizing a linear solver. The method further includes the steps of utilizing the characterized pore nodes to define one or more subgrids that represent a zone within the reservoir, wherein the zone includes at least one node of each porosity type; and wherein the linear solver is applied by subgrid or associated sub-grids.

摘要： A computer implemented method can include selecting a first flow rate model for a well, providing reservoir data to the first flow rate model, providing production history data to the first flow rate model, computing a solution to the first flow rate model and comparing the solution to production history data. A method can include implementing dual, triple or quad porosity models of a reservoir and history matching a model against actual well production data. A method can include comparing one or more models and determining whether a parameter has a unique solution. A system can include a computer readable medium having instructions stored thereon that, when executed by a processor, cause the processor to perform one or more methods.

摘要： An instrument for determining fluid properties is provided. The instrument (300) includes a tube (304) receiving the fluid, a single magnet (302) attached to the tube, and a single coil (306) wound around the single magnet. The single coil is coupled to a pulse current source (312) and receives a pulse current that creates a magnetic field in the single coil, the created magnetic field interacting with the single magnet to drive the tube to vibrate. The instrument further includes a detector (306) coupled to the tube, wherein the detector is coupled to measurement circuitry (310) and detects properties of the tube as it vibrates, and the measurement circuitry determines the fluid properties based on the detected properties. The instrument also includes a housing (314) enclosing the tube, the single magnet, and the single coil wound around the single magnet.

摘要： A formation tester for use in a subterranean well can include a probe which extends outward into contact with an earth formation, and an adjustable flow control device which limits an extension pressure applied to extend the probe. A method of testing a subterranean formation can include positioning a formation tester in a wellbore, extending a probe of the formation tester outward into contact with the formation, and limiting a force applied by the probe to the formation, the limiting being performed by variable actuation of a flow control device downhole. Another formation tester can include a probe which extends outward into contact with an earth formation, with a force applied by the probe to the formation being remotely adjustable downhole.

摘要： A method and apparatus for electronically coupling electronics in downhole tools without a harness is described. The apparatus includes one or more electronics boards, which may be disposed around a tool insert and electronically coupled using a backplane. The backplane may comprise one or more backplane segments, and each of the segments may comprise two printed circuit boards communicatively coupled to each other. The two printed circuit boards may be on opposite sides of a base metal ring and may be coupled to each other via connectors in a cavity of the base metal ring. Dampers may be placed between the base metal ring and each of the printed circuit boards. The printed circuit boards my optionally include an identification chip for storing information concerning the electronics boards coupled to the backplane. Additionally or alternatively, the printed circuit boards may optionally include active device chips that dynamically route signals based on which electronics boards are coupled to the backplane.
