  • Publication number: 20150083415
    Abstract: A composite having a solid particulate and a surface modifying treatment agent on the solid particulate wherein the surface modifying treatment agent has a hydrophobic tail and an anchor for adhering the hydrophobic tail onto the solid particulate. The anchor may be metal and the hydrophobic tail may be an organo-silicon material, a fluorinated hydrocarbon or both an organo-silicon material and a fluorinated hydrocarbon. The composite may be used as a proppant in a hydraulic fracturing operation as well as a sand control particulate in a gravel packing operation. The presence of the surface modifying treatment agent on the surface of the solid particulate reduces the generation of fines and dust as well as the migration of sand during a hydraulic fracturing operation or a sand control operation. The presence of the surface modifying treatment agent on the surface of the solid particulate further enhances the crush resistance of the solid particulate.

  • Publication number: 20100167965
    Abstract: Methods and compositions for forming a hydraulic fracture are disclosed herein. The methods and compositions make use of novel amphiphobic proppants. The amphiphobic properties of the disclosed proppant compositions provide several advantages over existing solutions. The hydrophobic nature of the proppant enhances recovery of fracture fluid from the fracture as well as prevents liquid build-up with the fracture. Additionally, the lipophobic nature of the proppant may enhance production of hydrocarbons from the fracture.

  • Patent number: 7662755
    Abstract: Sealant compositions and methods of using the same to isolate a subterranean zone are provided. The compositions include partially polymerized furfuryl alcohol/aldehyde, a coupling agent, a diluent, a curing agent, a ductility imparting agent, and a filler for increasing the compressive strengths of the sealant compositions. Methods of isolating a subterranean zone include pumping the foregoing sealant composition into a well bore down through a conduit and up through an annulus disposed between the conduit and the walls of the well bore. The sealant composition exhibits a sufficiently long cure time such that it does not harden until it reaches the annulus. Thus, the sealant composition effectively attaches the conduit to the walls of the well bore. The sealant composition is substantially resistant to degradation by waste chemicals disposed of in the well bore.

  • Publication number: 20090233819
    Abstract: A method of treating a sandstone-containing formation penetrated by a wellbore is carried out by forming a treatment fluid comprising an aqueous fluid containing a hydrogen fluoride source and an amorphous silica precipitation inhibitor. The treatment fluid is introduced into the formation through the wellbore at a pressure below the fracture pressure of the formation to facilitate dissolution of formation materials, optionally as a single stage. The amorphous silica inhibitor may be a polycarboxylate and/or polycarboxylic acid, an organosilane or a phosphonate compound. The amorphous silica inhibitor may be capable of inhibiting precipitation of amorphous silica so that the treatment fluid contains at least about 500 ppm of silicon after at least about 100 minutes subsequent to the treatment fluid being introduced into the formation.

  • Publication number: 20090093382
    Abstract: A method for pre-emptively reducing the production of water in an oil and gas well is provided. In one embodiment, a drill-in fluid having a relative permeability modifier (RPM) capable of impeding the production of water is introduced into the wellbore during drilling operations. In a second embodiment, a completion fluid having a relative permeability modifier (RPM) capable of impeding the production of water is introduced into the wellbore during completion operations. The drill-in fluid or completion fluid may further include an organosilicon compound to increase flow resistance and extend the effective RPM permeability application range.

  • Patent number: 7461697
    Abstract: Methods comprising: providing a treatment fluid that comprises a base fluid and a least a plurality of coated particulates, the coated particulates having been treated with a surface modification agent and coated with a hydrolysable coating; placing the treatment fluid into a subterranean formation via a well bore. Also provided are methods comprising: treating a particulate with a surface modification agent; coating the particulate with a hydrolysable coating that has an initial degradation rate to produce a coated particulate; placing the particulate in a subterranean formation; and allowing the hydrolysable coating to degrade at a second degradation rate that is slower than its initial degradation rate.
