摘要： An oil-water fractionation system is positioned within a wellbore on a subsurface end of a production tubing proximate to a production region. The fractionation system includes a permeable hydrophobic media for preferentially conveying an oil-enriched stream (reduced water-cut presence) from the production region into the production tubing, and a permeable oleophobic media for preferentially conveying a water-enriched stream (reduced oil-cut presence) into a second flow path. The permeable hydrophobic media and the permeable oleophobic media are in simultaneous hydraulic communication with the production region. The permeable hydrophobic media is manufactured with a relatively high effective permeability to oil, allowing the oil-enriched stream to flow through the permeable hydrophobic media into the production tubing. In contrast, the permeable oleophobic media is manufactured with a relatively high effective permeability to water, allowing the water-enriched stream to flow through the permeable oleophobic media into the second flow path.

摘要： Test systems and methods for evaluating erosion of a test sample. The test systems include a particulate distribution structure configured to receive a supplied particulate stream and to discharge a distributed particulate stream. The test systems also include a particulate acceleration structure configured to receive the distributed particulate stream and to generate an accelerated particulate stream. The test systems further include a test sample fixture configured to hold the test sample at a test sample location positioned such that the accelerated particulate stream is incident upon the test sample location. The methods include methods of operating the test systems.

摘要： Hydrocarbon wells including crosslinked polymer granules as a proppant, methods of forming the hydrocarbon wells, and methods of operating the hydrocarbon wells. The hydrocarbon wells include a wellbore that extends within a subsurface region and a downhole tubular that extends within the wellbore and defines a tubular conduit. The hydrocarbon wells also include a plurality of perforations formed within the downhole tubular and a plurality of fractures formed within the subsurface region. The hydrocarbon wells further include the proppant positioned within the plurality of fractures. The proppant includes a plurality of crosslinked polymer granules, and each crosslinked polymer granule has a characteristic dimension of at least 100 micrometers and at most 2 millimeters.

摘要： An oil-water fractionation system for use in a wellbore is described herein. The fractionation system is positioned within a wellbore on a subsurface end of a production tubing proximate to a production region. The fractionation system includes a permeable hydrophobic media for preferentially conveying an oil-enriched stream (reduced water-cut presence) from the production region into the production tubing, and a permeable oleophobic media for preferentially conveying a water-enriched stream (reduced oil-cut presence) into a second flow path. The permeable hydrophobic media and the permeable oleophobic media are in simultaneous hydraulic communication with the production region. The permeable hydrophobic media is manufactured with a relatively high effective permeability to oil, allowing the oil-enriched stream to flow through the permeable hydrophobic media into the production tubing. In contrast, the permeable oleophobic media is manufactured with a relatively high effective permeability to water, allowing the water-enriched stream to flow through the permeable oleophobic media into the second flow path.

摘要： A self-adjusting gas lift system and corresponding self-adjusting gas lift valve (GLV) are described herein. The self-adjusting gas lift system includes a number of self-adjusting GLVs that fluidically couple an annulus of a well to an interior of a production tubing of the well. Each of the self-adjusting GLVs is configured to open to allow a compressed gas to flow from the annulus to the interior of the production tubing when a pressure differential between an injection pressure of the compressed gas within the annulus and a production pressure of fluids within the production tubing is within an engineered range. Each of the self-adjusting GLVs is also configured to close when the pressure differential is outside the to engineered range.
