Publication number: 20110000667Abstract: A method of fracturing using deformable proppants minimizes proppant pack damage, without compromising the fracturing fluid's proppant transport properties during pumping, by use of deformable proppants. Selection of proppant is dependent upon the mechanical properties of the formation rock. The strength of the deformable proppant is dependent upon the modulus of the formation rock being treated such that the proppant is capable of providing, at the very least, a minimum level of conductivity in in-situ stress environments. The maximum elastic modulus of the deformable proppant is less than the minimum modulus of the formation rock which is being treated. The method is particularly applicable in fracturing operations of subterranean reservoirs such as those comprised primarily of coal, chalk, limestone, dolomite, shale, siltstone, diatomite, etc.Type: ApplicationFiled: September 3, 2010Publication date: January 6, 2011Inventors: Harold Dean Brannon, Allan Ray Rickards, Christopher John Stephenson, Russell L.

Patent number: 7772163Abstract: Well treating composites are composed of an organic lightweight material and a weight modifying agent. The organic lightweight material preferably forms the continuous phase and the weight modifying agent forms the discontinuous phase. The apparent specific gravity (ASG) of the organic lightweight material is less than the ASG of the well treating composite. The composite of the invention is particularly useful in hydraulic fracturing fluids as lightweight proppants as well as in sand control methods, such as gravel packing and frac packing A subterranean formation may be treated by injecting the well treating composite into the formation in order to increase fracture conductivity, reduce the generation of fines, reduced unwanted water production and/or reduce particulate production.Type: GrantFiled: January 9, 2008Date of Patent: August 10, 2010Assignee: BJ Services Company LLCInventors: Harold Dean Brannon, Allan Ray Rickards, Christopher John Stephenson

Patent number: 7726399Abstract: A subterranean formation having natural fractures, which is to be subjected to hydraulic fracturing, is first pre-treated with an ultra lightweight (ULW) proppant having an average particle size between from about 12/20 to about 40/70. The small ULW proppant flows into the natural fractures and packs the fractures. The formation is then subjected to hydraulic fracturing. The pre-treatment serves to enhance the effective propped fracture length of the formation during the hydraulic fracturing by reducing the loss of fluid from the subsequently pumped fracturing fluid. The method is applicable to hydrocarbon bearing formations as well as non-hydrocarbon bearing formations and has particular applicability to coal beds.Type: GrantFiled: September 30, 2004Date of Patent: June 1, 2010Assignee: BJ Services CompanyInventors: Harold Dean Brannon, William Dale Wood, Allan Ray Rickards, Christopher John Stephenson
