摘要： Methods and systems employing a flocculation polymer and microparticulates. The flocculation polymer flocculates the microparticulates to form micro-aggregates for use in forming complex fracture networks. Additionally, the flocculation causes the flocculation polymer to be removed from a treatment fluid due to its interaction with the microparticulates, thereby effectively cleaning the flocculation polymer from a subterranean formation. Individual microparticulates are synergistically used alone or in the presence of a de-aggregating agent to enhance complex fracture networks.

摘要： The disclosed embodiments include a method to determine formation properties of a downhole formation and a downhole logging system. In one embodiment, the method includes obtaining a first set of measurements of a formation from a multi-component induction logging tool and performing an inversion process of the first set of measurements to determine a first set of values for one or more formation properties of the formation. The method also includes determining a second set of values for the model parameters based on the measurements of a second logging tool. The method further includes comparing values of the first set of values with corresponding values of the second set of values to determine a data quality of the values of the first set of values and accepting the values of the first set of values if the data quality of the values is above a first threshold.

摘要： A retaining ring anti-migration system and method. A retaining ring anti-migration system for a centrifugal pump shaft includes a pair of trap sleeves that enclose a pair of retaining rings, one retaining ring around each end of the shaft enclosed by one trap sleeve, the pair of retaining rings configured to bound axial migration of the shaft both upwards and downwards. A retaining ring anti-migration system includes a retaining ring seated in a shaft groove extending circumferentially around an electric submersible pump (ESP) shaft, a trap sleeve extending around the ESP shaft adjacent to the retaining ring, the trap sleeve including a sleeve body secured to the ESP shaft such that the trap sleeve rotates with the ESP shaft, and a jacket extending axially from the sleeve body over an outer diameter of the retaining ring with a clearance between the shaft and the jacket.

摘要： A well monitoring system includes a plurality of transmitter coils coupled to an exterior of a casing positioned within a wellbore, wherein one or more first transmitter coils are positioned at a first location and one or more second transmitter coils are positioned at a second location axially offset from the first location. At least one receiver coil is coupled to the exterior of the casing and positioned at the second location. A power source is communicably coupled to the one or more first and second transmitter coils. The one or more first transmitter coils generates a magnetic field detectable by the at least one receiver coil, and the one or more second transmitter coils generates a bucking signal that minimizes a direct coupling between the one or more first transmitter coils and the at least one receiver coil.

摘要： A system for controlling fluid flow in a subterranean well includes a first valve, a control line fluidly coupled to the first valve, an equalizing line disposed externally to and separate from the first valve, and at least a second valve disposed in the equalizing line and in fluid communication with the control line. The first valve includes a body defining a lumen, and an upper portion, and a lower portion. The equalizing line is in fluid communication with the lumen between the upper portion and the lower portion of the body. The second valve equalizes a pressure between the upper and lower portions of the body.

摘要： A variety of systems, methods, and compositions are disclosed, including, a method for treating a subterranean formation, the method comprising: injecting a pad fluid into the subterranean formation at a pressure sufficient to create at least one fracture in the subterranean formation; injecting a first treatment fluid into the at least one fracture, wherein the first treatment fluid comprises: an aqueous base fluid, and a first proppant particulate; allowing the first proppant particulate to gravitationally migrate into a portion of the at least one fracture; injecting a second treatment fluid into the at least one fracture, wherein the second treatment fluid comprises: a suspension base fluid comprising a viscosity of about 50 cP to about 10,000 cP, and a second proppant particulate; and allowing the fracture to close, thereby forming a full proppant pack and a partial proppant pack in the at least one fracture.

摘要： A method that includes introducing a first fluid at a first flow rate into a first end of a channel of a hydraulic energy transfer system, introducing a second fluid at a second flow rate into a second end of the channel opposite the first end, wherein the first flow rate is lower than the second flow rate, and operating the hydraulic energy transfer system to output a third fluid comprising the first fluid and a portion of the second fluid and exhibiting a step-change in concentration of the first fluid. The first fluid is proppant slurry introduced at a first pressure, the second fluid is a clean fluid introduced at a second pressure higher than the first pressure, and third fluid is a fracturing fluid exhibiting the step-change in proppant concentration. The hydraulic energy transfer system includes a rotary isobaric pressure exchanger.
