Abstract: Proppant pillar placement in a fracture with a stabilized slurry treatment fluid. A method of placing a proppant pack by injecting a well treatment fluid comprising proppant and a stabilized slurry, and a slurry destabilizing system to consolidate solids from the slurry, and placing the proppant in the fracture in a plurality of proppant clusters forming pillars spaced apart by fluid flow channels from the formation through the fracture toward the wellbore. Also, a system for implementing the method, and the propped fracture system obtained as a result of placing the proppant pack into the fracture according to the method.

Abstract: A fluid comprising a plurality of particulates having an Apollonian particle size distribution dispersed in a carrier fluid optionally comprising a surfactant, the particulates, the carrier fluid, or both comprising a degradable oleaginous fluid. Methods to utilize the fluid are also disclosed.

Abstract: The current application discloses methods and systems for preparing a wellbore treatment fluid precursor consolidated as one or more solid bodies; delivering the solid bodies to a logistics facility; and preparing a wellbore treatment fluid from the solid bodies. In some embodiments, the wellbore treatment fluid is a fracturing fluid for conducting a hydraulic fracturing operation on a subterranean formation penetrated by a wellbore.

Abstract: A thickened composition comprising a polymer, a divalent ions source, water and cement is disclosed. Such composition enables fluid loss reduction and higher gel strength. This may be useful for treating a well for example as a fluid spacer or a scavenger; this may also be used a hydraulic fracturing fluid.

Abstract: Incorporation of carbonaceous materials in a cement slurry increases the linear thermal-expansion coefficient of the set cement. When placed in a subterranean well having at least one casing string, cement sheaths with linear thermal-expansion coefficients similar to that of the casing will be subjected to lower compressive and tensile stresses during downhole-temperature changes. Such cement slurries are particularly advantageous in the context of thermal-recovery wells.

Abstract: A method of placing particulate blend into a fracture formed in a subterranean formation from a wellbore comprises injecting through the wellbore a first treatment fluid to initiate or propagate the fracture in the subterranean formation; wherein the first treatment fluid comprises a particulate blend slurry; the particulate blend comprising at least a first amount of particulates having a first average particle size between about 100 and 5000 micrometers and at least a second amount of particulates having a second average particle size between about three and twenty times smaller than the first average particle size; injecting through the wellbore a second treatment fluid having a viscosity different from the first treatment fluid; and forming with the particulate blend slurry a plurality of particulate-rich clusters spaced apart by particulate-free regions forming open channels.

Abstract: A method of treating a subterranean formation of a well bore comprises providing a treatment fluid comprising a carrier fluid, a particulate material, a viscosifying agent and fumed silica, wherein fumed silica is in such concentration to reduce the settling rate of the particulate material in the treatment fluid; and introducing the treatment fluid into the wellbore.

Abstract: A method of treating a subterranean formation of a well bore comprises providing a treatment fluid comprising a carrier fluid, a particulate material, a surfactant and micelles, wherein micelles are stabilized by the surfactant and act as particles in the treatment fluid; and introducing the treatment fluid into the wellbore.

Abstract: A composition, treatment fluid and method using hydrolyzable fines. A treatment fluid, which may optionally include a high solids content fluid (HSCF) and/or an Apollonianistic solids mixture, includes a fluid loss control agent comprising a dispersion of hydrolyzable fines, optionally with one or more of a surfactant, plasticizer, dispersant, degradable particles, reactive particles and/or submicron particles selected from silicates, ?-alumina, MgO, ?-Fe2O3, TiO2, and combinations thereof.
