Abstract: A method of heterogeneous proppant placement in a subterranean fracture is disclosed. The method comprises injecting well treatment fluid including proppant (16) wherein the proppant comprises from 1 to 100 percent in weight of stiff, low-elasticity and low-deformability elongated particles (34) and proppant-spacing filler material called a channelant (18) through a wellbore (10) into the fracture (20), heterogeneously placing the proppant in the fracture in a plurality of proppant clusters or islands (22) spaced apart by the channelant (24), and removing the channelant filler material (24) to form open channels (26) around the pillars (28) for fluid flow from the formation (14) through the fracture (20) toward the wellbore (10). The proppant and channelant can be segregated within the well treatment fluid, or segregated during placement in the fracture. The channelant 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 fibers to provide reinforcement and consolidation of the proppant and, additionally or alternatively, to inhibit settling of the proppant in the treatment fluid.

Abstract: 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.

Abstract: Methods for initiating chemical reactions in a wellbore include delivering one or more reactive components via a carrier fluid to the wellbore. The one or more reactive components delivered to the wellbore are configured to enable one or more chemical reactions to occur. The one or more chemical reactions are carried out until a threshold volume of the one or more reactive components is delivered to the wellbore.

Abstract: A method for drilling and fracturing a subterranean formation includes drilling a substantially horizontal pilot well from a previously drilled vertical pilot well. A plurality of substantially vertical sidetracks is drilled from the horizontal pilot well. Fracturing fluid is pumped into the plurality of vertical sidetracks to hydraulically fracture the subterranean formation.

Abstract: Methods of delivering reactive components to a geological formation disclosed herein include generating a plurality of microholes along a wellbore, the plurality of microholes comprising one or more openings, and the plurality of microholes are configured to connect the wellbore to the geological formation. Methods further include delivering the one or more reactive components to the plurality of microholes via a carrier fluid, wherein the one or more reactive components are configured to enable one or more chemical reactions to occur, and wherein the carrier fluid is configured to expand, and controlling a flow rate of the one or more reactive components based on whether a volume of the one or more reactive components delivered to the plurality of microholes is greater than a threshold volume.
