20090286700 | Heterogeneous Proppant Placement in a Fracture with Removable Channelant Fill - A method of heterogeneous proppant placement in a subterranean fracture is disclosed. The method comprises injecting well treatment fluid including proppant ( | 11-19-2009 |
20110056684 | DEGRADABLE FIBER SYSTEMS FOR STIMULATION - A method for minimizing the amount of metal crosslinked viscosifier necessary for treating a wellbore with proppant or gravel is given. The method includes using fibers to aid in transporting, suspending and placing proppant or gravel in viscous carrier fluids otherwise having insufficient viscosity to prevent particulate settling. Fibers are given that have properties optimized for proppant transport but degrade after the treatment into degradation products that do not precipitate in the presence of ions in the water such as calcium and magnesium. Crosslinked polymer carrier fluids are identified that are not damaged by contaminants present in the fibers or by degradation products released by premature degradation of the fibers. | 03-10-2011 |
20110083849 | HETEROGENEOUS PROPPANT PLACEMENT IN A FRACTURE WITH REMOVABLE CHANNELANT FILL - A method of heterogeneous proppant placement in a subterranean fracture is disclosed. The method comprises injecting a first treatment fluid comprising a gas and substantially free of macroscopic particles through a wellbore to initiate a fracture in a subterranean formation; injecting a second treatment fluid comprising proppant and channelant through the wellbore into the fracture; placing the proppant in the fracture in a plurality of proppant clusters forming pillars spaced apart by the channelant; and removing the channelant to form open channels around the pillars for fluid flow from the subterranean formation through the fracture toward the wellbore. | 04-14-2011 |
20110114313 | HETEROGENEOUS PROPPANT PLACEMENT IN A FRACTURE WITH REMOVABLE CHANNELANT FILL - A method of heterogeneous proppant placement in a subterranean fracture is disclosed. The method comprises injecting well treatment fluid including proppant ( | 05-19-2011 |
20120267103 | DEGRADABLE FIBER SYSTEMS FOR STIMULATION - A method for minimizing the amount of metal crosslinked viscosifier necessary for treating a wellbore with proppant or gravel is given.

20120325472 | HETEROGENEOUS PROPPANT PLACEMENT IN A FRACTURE WITH REMOVABLE EXTRAMETRICAL MATERIAL FILL - A method of heterogeneous proppant placement in a subterranean fracture is disclosed. The method comprises injecting well treatment fluid including proppant ( | 12-27-2012 |
20130146292 | HETEROGENEOUS PROPPANT PLACEMENT IN A FRACTURE WITH REMOVABLE EXTRAMETRICAL MATERIAL FILL - A method of injecting well treatment fluid including proppant and proppant-spacing filler material through a wellbore into the fracture, heterogeneously placing the proppant in the fracture in a plurality of proppant clusters or islands spaced apart by the material, and removing the filler material to form open channels around the pillars for fluid flow from the formation through the fracture toward the wellbore. The proppant and channelant can be segregated within the well treatment fluid, or segregated during placement in the fracture. The filler material can be dissolvable particles, initially acting as a filler material during placement of the proppant in the fracture, and later dissolving to leave the flow channels between the proppant pillars. The well treatment fluid can include extrametrical materials to provide reinforcement and consolidation of the proppant and/or to inhibit settling of the proppant. | 06-13-2013 |
20140138085 | HETEROGENEOUS PROPPANT PLACEMENT IN A FRACTURE WITH REMOVABLE CHANNELANT FILL - A method of heterogeneous proppant placement in a subterranean fracture is disclosed. The method comprises injecting well treatment fluid including proppant ( | 05-22-2014 |
20140262249 | HYDRAULIC FRACTURING WITH EXOTHERMIC REACTION - Method of stimulating subterranean formations for are given in which a thermite is placed downhole and then ignited. The thermite may be ignited with a downhole tool, the fracture may be mapped, and the thermite-affected region of the formation may be reconnected to the surface after the thermite reaction through the original or a second wellbore. | 09-18-2014 |
20140262264 | COMPOSITIONS AND METHODS FOR INCREASING FRACTURE CONDUCTIVITY - A method for treating a subterranean formation penetrated by a wellbore, comprising: providing a treatment slurry comprising a carrying fluid, a solid particulate and an agglomerant; injecting the treatment slurry into a fracture to form a substantially uniformly distributed mixture of the solid particulate and the agglomerant; and transforming the substantially uniform mixture into areas that are rich in solid particulate and areas that are substantially free of solid particulate, wherein the solid particulate and the agglomerant have substantially dissimilar velocities in the fracture and wherein said transforming results from said substantially dissimilar velocities is provided. | 09-18-2014 |
20140366621 | Gas Sorption Analysis Of Unconventional Rock Samples - Systems and methods for gas sorption analysis, or analogous practices, of samples from unconventional reservoirs are described.
