Abstract: An electrical stability testing device includes a cup configured to receive a fluid sample. The testing device also includes a pair of electrodes positioned at least partially within the cup. The electrodes are spaced apart from one another by a predetermined gap. The electrodes are configured to have the fluid sample positioned within the predetermined gap while performing an ES test on the fluid sample in the cup. The testing device also includes a wiper positioned at least partially within the cup. The wiper is configured to pass between the electrodes after the ES test has concluded. A width of the wiper is greater than the predetermined gap between the electrodes. The wiper is configured to deform as the wiper passes through the predetermined gap such that the width becomes substantially equal to the predetermined gap and sides of the wiper contact ends of the electrodes to clean the electrodes.

Abstract: The disclosure pertains to methods for completing a well may comprise lowering a coiled-tubing in the well thus forming an annulus between the casing and the coiled-tubing, pumping down said annulus a treatment fluid above the fracturing pressure of the formation while also pumping fluid through the coiled tubing. The methods may also comprise monitoring in real-time the bottom hole pressure and increasing the pump rate through the coiled-tubing if an increase of bottom hole pressure is observed.

Abstract: A technique for pre-storing an application fluid in coiled tubing for use in a downhole application. The technique includes filling the coiled tubing with the application fluid in a manner that utilizes pressures substantially below that of the pressures utilized in the downhole application itself. The coiled tubing may then be charged to near the application pressure and placed in hydraulic communication with a well for the downhole application. Thus, the coiled tubing may serve as an application fluid storage device without the requirement of coiled tubing deployment or associated equipment and related costs.

Abstract: The current application aims at methods and systems for preparing a pump-ready treatment fluid, delivering the pump-ready treatment fluid to a location operationally coupled to a wellsite, providing the pump-ready treatment fluid to a pump; and pumping the pump-ready treatment fluid into a wellbore. In some embodiments, the treatment fluid is a fracturing fluid for conducting a hydraulic fracturing operation on a subterranean formation penetrated by a wellbore.

Abstract: A method of heterogeneous proppant placement in a subterranean fracture is disclosed. The method comprises injecting a first treatment fluid comprising a gas and substantially free of macroscopic particles through a wellbore to initiate a fracture in a subterranean formation; injecting a second treatment fluid comprising proppant and channelant through the wellbore into the fracture; placing the proppant in the fracture in a plurality of proppant clusters forming pillars spaced apart by the channelant; and removing the channelant to form open channels around the pillars for fluid flow from the subterranean formation through the fracture toward the wellbore.

Abstract: A method of heterogeneous proppant placement in a subterranean fracture is disclosed. The method comprises injecting well treatment fluid including proppant (16) wherein the proppant comprises from 1 to 100 percent in weight of stiff, low-elasticity and low-deformability elongated particles (34) and proppant-spacing filler material called a channelant (18) through a wellbore (10) into the fracture (20), heterogeneously placing the proppant in the fracture in a plurality of proppant clusters or islands (22) spaced apart by the channelant (24), and removing the channelant filler material (24) to form open channels (26) around the pillars (28) for fluid flow from the formation (14) through the fracture (20) toward the wellbore (10). The proppant and channelant can be segregated within the well treatment fluid, or segregated during placement in the fracture.
