摘要： A method to provide a plurality of fractures in a subterranean formation includes providing an essentially horizontal wellbore in the subterranean formation and providing a casing in the essentially horizontal wellbore. The method also includes providing communication between an inside of the casing and the subterranean formation at a plurality of locations along the length of the horizontal wellbore and providing a mortar slurry within the casing. The method further includes initiating a plurality of fractures from the plurality of locations and propagating the plurality of fractures by adding mortar slurry to the wellbore. A pressure inside the casing within the subterranean formation is above a fracture opening pressure while the plurality of fractures is propagating.

摘要： A method of producing subterranean fractures in geologic formations for the extraction of hydrocarbons includes flowing an air and fuel mixture into a well hole. The well hole may then be sealed with a packer plug creating a compression chamber with the air and fuel mixture. A liquid, such as water, may be pumped into the well hole to create pressure in the compression chamber. The build-up of pressure eventually causes auto-ignition of the air and fuel mixture which fractures the formation. The water may then rush into the compression chamber which thermally shocks the area causing additional fractures. The water may vaporize to steam and thoroughly disinfect the well hole eliminating the need for added biocides.

摘要： A method for controlling fluid loss into the pores of an underground formation during fracturing operations is provided. Nanoparticles are added to the fracturing fluid to plug the pore throats of pores in the underground formation. As a result, the fracturing fluid is inhibited from entering the pores. By minimizing fluid loss, higher fracturing fluid pressures are maintained, thereby resulting in more extensive fracture networks. Additionally, nanoparticles minimize the interaction between the fracturing fluid and the formation, especially in water sensitive formations. As a result, the nanoparticles help maintain the integrity and conductivity of the generated, propped fractures.
