Abstract: Methods of treating a subterranean formation are described. The methods include introducing a treatment fluid that includes a friction reducing polymer (e.g., a cationic friction reducing polymer) into the subterranean formation. The cationic friction reducing polymer is allowed to degrade and release choline chloride or polyDADMAC, which can each act as a clay stabilizer.

Abstract: A downhole fluid composition having a saccharide gelling agent, an oxidative breaker, and a sequestering agent. The sequestering agent is hydrocarbon miscible and inert to oxidation by the oxidative breaker. The sequestering agent sequesters the oxidative breaker or an activator for the oxidative breaker, whereby oxidation of the gelling agent is inhibited. The downhole fluid may also include a proppant. Upon contacting hydrocarbons downhole or reaching a predetermined temperature, the sequestering agent releases the oxidative breaker or activator thereby oxidizing the saccharide gelling agent.

Abstract: Methods of treating a subterranean formation are described. The methods include introducing a treatment fluid that includes a friction reducing polymer (e.g., a cationic friction reducing polymer or an anionic friction reducing polymer) into the subterranean formation. The cationic friction reducing polymer is allowed to degrade and release choline chloride or polyDADMAC, which can each act as a clay stabilizer. The anionic friction reducing polymer is allowed to degrade and release AMPS, which can act as a surfactant, a scale inhibitor, a paraffin inhibitor, or an asphaltene inhibitor, or polyacrylic acid, which can act as a scale inhibitor.

Abstract: Fluid mixing systems and methods to dynamically adjust a density of a fluid mixture are disclosed. A method to dynamically adjust a density of a fluid mixture includes obtaining data indicative of one or more characteristics of a mixture of a first fluid having a first density and a second fluid having a second density that is less than the first density. The method also includes determining, based on the one or more characteristics, an amount of additive to add to the mixture, and releasing a volume of the first fluid, which when mixed with the second fluid, forms a mixture having a ratio of the first fluid to the second fluid. The method further includes mixing the first fluid with the second fluid. The method further includes adding the determined amount of additive to the mixture having the ratio of the first fluid to the second fluid.

Abstract: A method may comprise introducing a first traceable solid particulate into a first formation zone of one or more subterranean formations, wherein the first traceable solid particulate may comprise a first soluble tracer coated onto a first solid particulate. The method may also comprise introducing a second traceable solid particulate into a second formation zone of the one or more subterranean formations, wherein the second traceable solid particulate may comprise a second soluble tracer coated onto a second solid particulate, wherein the second tracer and the first tracer may have a different chemical identity. The method may further comprise recovering produced fluid from the one or more subterranean formations and monitoring concentrations of at least the first soluble tracer and the second soluble tracer in the produced fluid.

Abstract: A trocar having a safety shield control mechanism that prevents the inner cannula from rotating and from moving axially when in the locked position. The safety shield control mechanism applies consistent pressure on the safety shield and has an open architecture for ease of sterilization. The trocar provides holding levels for different sizes of hands.

Abstract: A universal fixture has an alignment surface which temporarily holds a heat sink for installation of a plurality of electrical devices on its working surfaces. The fixture rotates about an axis to place an alignment surface in a first or second mounting position corresponding to a generally vertical orientation of the alignment surface. This corresponds to a horizontal position of the opposite first and second sides of the heat sink temporarily mounted thereon. Double rows of openings in the rotatable alignment member are universal in the sense they are configured to accept connection pins of the common packages to be clamped against the opposite sides of the heat sink. This permits one fixture to accommodate a variety of devices and arrangements. A unique standoff device supports smaller packages above the alignment surface to permit clamping across larger and smaller electrical devices without the necessity of attempting to manipulate and hold the devices by hand during the clamping operation.
