Abstract: Compositions and methods for increasing a stimulated reservoir volume in a hydrocarbon-bearing formation in fluid communication with a wellbore, one method including drilling a plurality of lateral extensions at varying depths in the formation extending from a vertical wellbore using slickwater hydraulic fracturing fluid, the slickwater hydraulic fracturing fluid comprising at least one friction reducer; and injecting an exothermic reaction component into the plurality of lateral extensions to create a plurality of fractures extending outwardly from and between the plurality of lateral extensions to create a multilateral fracture network.

Abstract: A multistage plunger lift system includes an upper production tubing segment positioned in a wellbore uphole of a lower production tubing segment, with the upper segment having a greater diameter than the lower segment. A lower travelling plunger and an upper traveling plunger are sized and configured to fit and travel within the lower segment and the upper segment, respectively. A plunger lift tool is positioned in the upper segment between the upper plunger and the lower plunger, and includes within its main body a fluid passageway with a one-way valve. A plunger receptacle sleeve at the bottom end of the lift tool receives the lower plunger and includes one or more vents configured to allow fluids to flow around the lower plunger when the lower plunger is received within the plunger receptacle sleeve.

Abstract: A downhole pump includes a housing, a plunger that is disposed within the housing, and a rod that is secured to the plunger. The housing includes a magnet that is disposed at an uphole end of the housing. The plunger includes a traveling valve that is disposed at a downhole end of the plunger. The rod includes a conducting shaft that is attached to an uphole end of the plunger. The conducting shaft is configured to extend a magnetic field generated by the magnet when the conducting shaft is positioned adjacent the magnet to magnetically force the traveling valve into an open state.
