    Abstract: A method and apparatus using a multiple transducer acoustic logging tool to detect fractures surrounding a borehole, particularly fractures that do not intersect the borehole wall. The transducers are actuated to produce broad band width pulses and signal enhancement techniques are used to determine fracture width, orientation and distance from the borehole wall.

    Abstract: An apparatus for separating fluids and controlling flow of production fluid includes a diversion assembly configured to receive production fluid produced from a subterranean region, the diversion assembly including an inflow conduit in fluid communication with a first outflow conduit and a second outflow conduit, the first outflow conduit in fluid communication with a surface location. The apparatus also includes a separation assembly including a hydrophilic ribbon and an oleophilic ribbon configured to be immersed in the production fluid, at least part of the hydrophilic ribbon and the oleophilic ribbon configured to move with the production fluid, the oleophilic ribbon configured to redirect a flow of hydrocarbons into the first outflow conduit, and the hydrophilic ribbon configured to redirect a flow of water-based fluid into the second outflow conduit.

    Abstract: A method for performing a formation fluid test in a borehole penetrating a subsurface formation includes disposing a fluid tester in the borehole, extracting a sample of fluid from the subsurface formation using the fluid tester, and analyzing the sample using the fluid tester to provide test data for a process used to analyze the sample. The method also includes fitting an equation to the test data and calculating a ratio of a first derivative of the equation to a second derivative of the equation. The method further includes continuing to extract the sample from the subsurface formation in response to the ratio indicating a clean sample will be forthcoming and terminating the extracting of the sample from the subsurface formation in response to the ratio indicating a clean sample will not be forthcoming.
