Methods and Compositions for Stabilizing Fracture Faces During Hydraulic Fracturing Treatments

A method of treating a subterranean formation including introducing a preflush solution comprising a first aqueous base fluid and a surfactant onto the face of a fracture in a subterranean formation with particulates in the fracture; introducing a stabilizing composition onto the fracture face of the formation and onto the particulates proximate the fracture face, the composition including a second aqueous-based fluid; a silane-based resin; and a silane-based curing agent; allowing the stabilizing composition to consolidate the particulates proximate the fracture face, thereby stabilizing the fracture face and proximate particulates in the fracture. A method includes introducing a conformance treatment fluid into at least a portion of a subterranean formation, said treatment fluid including: an aqueous-based fluid; a silane-based resin; and a silane-based curing agent; and allowing the conformance treatment fluid to at least partially seal the pores of the formation.

NANOTUBE MEDIATION OF DEGRADATIVE CHEMICALS FOR OIL-FIELD APPLICATIONS

Discrete, individualized carbon nanotubes having targeted, or selective, oxidation levels and/or content on the interior and exterior of the tube walls can be used for nanotube-mediated controlled delivery of degradative molecules, such as oxidizers and enzymes, for oil-field drilling applications. A manufacturing process using minimal acid oxidation for carbon nanotubes may also be used which provides higher levels of oxidation compared to other known manufacturing processes.

Treatment fluids containing a boron trifluoride complex and methods for use thereof

Treatment fluids for use in subterranean formations, particularly sandstone and other siliceous formations, may contain a source of fluoride ions to aid in mineral dissolution. In some cases, it may be desirable to generate the fluoride ions from a fluoride ion precursor, particularly a hydrofluoric acid precursor, such as a boron trifluoride complex. Methods described herein can comprise providing a treatment fluid that comprises an aqueous base fluid, a boron trifluoride complex, and a chelating agent composition, and introducing the treatment fluid into a subterranean formation.

Use of nano-sized phyllosilicate minerals in viscoelastic surfactant fluids

Nano-sized clay minerals enhance the viscosity of aqueous fluids that have increased viscosity due to the presence of viscoelastic surfactants (VESs). In one non-limiting theory, the nano-sized phyllosilicate mineral viscosity enhancers associate, link, connect, or relate the VES elongated micelles into associations thereby increasing the viscosity of the fluid, possibly by mechanisms involving chemisorption or surface charge attractions. The nano-sized phyllosilicate mineral particles, also called clay mineral nanoparticles, may have irregular surface charges. The higher fluid viscosity is beneficial to crack the formation rock during a fracturing operation, to reduce fluid leakoff, and to carry high loading proppants to maintain the high conductivity of fractures.

Heat removal in drilling and production operations

Working fluids, such as drilling fluids, may remove heat from other fluids, tools, equipments and environments and transfer it to other locations by using reversible phase change elements. The heat removal occurs through the absorption of heat by one or more phase transitions or a sequence of phase transitions in the elements of the working fluid. For instance, heat is absorbed when the phase change portions of the reversible phase change elements change phase including, but not necessarily limited to, a change from solid to smectic liquid crystal, from solid to nematic liquid crystal, from smectic liquid crystal to isotropic liquid, from nematic liquid crystal to isotropic liquid, from solid to isotropic liquid, and sequences and combinations thereof. Heat is released when the phase change reverses. These phase changes are first-order transitions and are associated with a latent heat or enthalpy.
