摘要： An apparatus comprising first and second fluid intakes, a pump, and a sample chamber, may be positioned in a borehole penetrating a subterranean formation. A method of use thereof may comprise drawing fluid from the subterranean formation and into the first and second fluid intakes using the pump, discharging into the borehole at least a portion of the fluid drawn into the second fluid intake, and selectively diverting at least a portion of the fluid drawn into the first fluid intake to the sample chamber.

摘要： Modular pumpouts and flowline architecture are described. An example apparatus includes a downhole tool to sample fluid from a subterranean formation, and a plurality of fluidly coupled pump modules disposed on the downhole tool. Each of the pump modules includes: a pump having a pump inlet and a pump outlet, where the pump inlet is coupled to a first flowline; a first valve assembly having first, second and third ports, wherein the first port is coupled to the first flowline, the second port is coupled to the pump outlet, and the third port is coupled to the first flowline; and a second flowline not fluidly coupled to the first valve assembly or the pump.

摘要： Cleanup monitoring and prediction in real time targeting estimation of pumpout volume versus final contamination, including detecting breakthrough of formation fluid to a sampling tool and detecting transition of cleanup regime from a predominantly circumferential cleanup regime to a predominantly vertical cleanup regime. Similar workflow can be employed for estimating contamination at the end of cleanup production for a given pumpout volume.

摘要： The present invention provides an apparatus for use in perforating a well having a plurality of explosive charges. Each explosive charge is adapted to generate a perforation tunnel in the formation adjacent to the well. In one embodiment, explosive charges are oriented to create perforation tunnels that converge at a location within the formation in order to create a fracture initiation plane capable of mitigating or avoiding hydraulic fracturing complications.

摘要： Generally, an apparatus for use in a wellbore includes a flow conduit and a structure defining a tortuous fluid path proximate the flow conduit, where the tortuous fluid path receives a flow of fluid. The tortuous fluid path is defined by at least first and second members of the structure, and the first and second members are movable with respect to each other to adjust a cross-sectional flow area of the tortuous fluid path.
