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.

A method for treating a subterranean formation penetrated by a wellbore, comprising: providing a treatment slurry comprising a carrying fluid, a solid particulate and an agglomerant; injecting the treatment slurry into a fracture to form a substantially uniformly distributed mixture of the solid particulate and the agglomerant; and transforming the substantially uniform mixture into areas that are rich in solid particulate and areas that are substantially free of solid particulate, wherein the solid particulate and the agglomerant have substantially dissimilar velocities in the fracture and wherein said transforming results from said substantially dissimilar velocities is provided.

Compositions and methods for increasing fracture conductivity

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.

A method of heterogeneous proppant placement in a subterranean fracture is disclosed. The method comprises injecting well treatment fluid including proppant () and proppant-spacing filler material () through a wellbore () into the fracture (), heterogeneously placing the proppant in the fracture in a plurality of proppant clusters or islands () spaced apart by the material (), and removing the filler material () to form open channels () around the pillars (). The filler material can be dissolvable particles, initially acting as a consolidator during placement of the proppant in the fracture, and later dissolving to leave flow channels between the proppant pillars. The well treatment fluid can include extrametrical materials to provide reinforcement and consolidation of the proppant and, additionally or alternatively, to inhibit settling of the proppant in the treatment fluid.

A system includes a regional blending facility having a number of bulk receiving facilities, where each bulk facility receives and stores a particle type having a distinct size modality, a bulk moving device that transfers particles between the bulk receiving facilities and of a blending/continuously receiving vessel and/or a mixer, and a carrying medium vessel. The mixer receives particles from the blending/continuously receiving vessel and/or the bulk moving device, receives a carrying medium from the carrying medium vessel, mixes the particles with the carrying medium, and provides a mixed treatment fluid. The system includes a fluid conduit that fluidly couples a wellsite location with the regional blending facility, where the fluid conduit delivers the mixed treatment fluid to the wellsite and/or delivers produced fluid from a wellbore positioned at the wellsite to the regional blending facility.

System and method for delivering treatment fluid

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.

A method that is usable with a well includes introducing solids into a pneumatic stream to produce a solids-containing pneumatic stream; communicating the solids-containing pneumatic stream to a blender assembly to mix the solids with at least one other material to produce a flow; and pumping the flow into the well.

Solids delivery apparatus and method for a well

A technique enables improvements in hydraulic fracturing treatments on heterogeneous reservoirs. Based on data obtained for a given reservoir, a fracturing treatment material is used to create complex fractures, which, while interacting with the interfaces and planes of weakness in the reservoir, develop fracture connectors, e.g. step-overs, which often grow for short distances along these planes of weakness. The technique further comprises closing or sealing at least one of the fracture connectors to enable reinitiation of fracturing from the truncated branches, and to subsequently develop additional connectors. As a result, the overall fracturing becomes more complex (more branches and more surface area per unit reservoir volume is created), which leads to an increase in the effective fracture area and improved fluid flow through the reservoir.
