Abstract: Non-spherical particulates are useful in the stimulation of subterranean formations. A proppant pack composed of the non-spherical particulates exhibits greater porosity than a corresponding proppant pack composed of spherical particulates. In addition, the non-spherical particulates exhibit higher conductivity at higher stresses than spherical shaped particulates.

Abstract: Cements, such as alkali activated binder, may be used as coatings on proppants, such as sand, to improve the strength thereof. The resulting chemically bonded phosphate ceramic (CBPC) coated proppants show increased compressive strength between about 60 to about 130 MPa, as well as produced fines of lower than about 10 wt % at 10,000 psi closure stress.

Abstract: A proppant may include particles including a sintered ceramic composition, wherein the particles have a particle size distribution such that less than 25 wt. % of the particles have a particle size less than 100 mesh, and wherein the particles have a particle size distribution such that less than 1 wt % of the particles have a particle size greater than 60 mesh. The particles may have a sphericity ranging from 0.4 to 0.9. A proppant may include particles including a sintered ceramic composition, wherein the proppant has a conductivity of at least 1.5 times the conductivity of 100 mesh sand. A method of treating a subterranean area around a well bore may include providing a fracturing fluid including such proppants, and injecting the fracturing fluid into the subterranean area around the well bore.

Abstract: Methods and compositions useful for subterranean formation treatments, such as hydraulic fracturing treatments and sand control that include porous materials. Such porous materials may be selectively configured porous material particles manufactured and/or treated with selected glazing materials, coating materials and/or penetrating materials to have desired strength and/or apparent density to fit particular downhole conditions for well treating such as hydraulic fracturing treatments and sand control treatments. Porous materials may also be employed in selected combinations to optimize fracture or sand control performance, and/or may be employed as relatively lightweight materials in liquid carbon dioxide-based well treatment systems.

Abstract: Methods for the treatment of subterranean wells involving injecting a first fracturing fluid into a formation, and then injecting at least a second fracturing fluid into the formation in order to create extended conductive channels through a formation are described. The fracturing fluids can be similar in density, viscosity, pH and the other related characteristics. Alternatively, the fracturing fluids can differ in their densities, viscosities, and pH, allowing for variations in the conductive channels formed. Propping agents can also be included in one or both of the injected fluids, further enhancing the conductive channels formed. The described methods aid in minimizing proppant flowback problems typically associated with hydraulic fracturing techniques.

Abstract: Cement compositions including mixtures of substantially elastic material and cement that may be formulated exhibit reduced bulk volume shrinkage during curing as compared to conventional cement compositions. In one application, such cement compositions may be used for cementing in substantially closed system, such as the interior of a mold used for producing preformed concrete items.
