Abstract: Described is a drilling fluid composition with enhanced hole cleaning properties and a method of its use. Following an indication of sticking of a drill pipe during a drilling operation, a drilling fluid composition, including a first exothermic reactant, is injected into a subterranean formation. Then, a drilling fluid composition, including a second exothermic reactant, is injected into the subterranean formation. An exothermic reaction is allowed to occur between the first exothermic reactant and the second exothermic reactant within the subterranean formation.

Abstract: A method includes assembling a liner system by disposing a fiber optic cable circumferentially around an inner tube liner and locating an outer tube liner around the inner tube liner. The fiber optic cable is located between the inner tube liner and the outer tube liner. The method also includes spooling out the liner system, in a lay-flat state, into a conduit of a tubular structure positioned in the well, terminating spooling out the liner system when a select length of the liner system has been deployed in the conduit of the tubular structure, and securing the select length of the liner system deployed into the tubular structure at a surface above the well.

Abstract: A wellbore tool may include a port through the body and a first rupture disk disposed on the body and covering the port, the body defining a first interior chamber and a second interior chamber, with a liquid-permeable membrane separating the first interior chamber and the second interior chamber within the body. The body may be configured to retain a first solid reactant in the first interior chamber and a second solid reactant in the second interior chamber, wherein the first rupture disk is configured to rupture at a pressure differential downhole. A method for livening a well may include lowering the wellbore tool into a wellbore.

Abstract: Systems and methods of enhancing oil recovery with an electrochemical apparatus include introducing the electrochemical apparatus into an injection well bore. The electrochemical apparatus includes an anode, a cathode and an interior wall, the interior wall defining an interior that contains both the anode and the cathode. The electrochemical apparatus is operated such that injection water of the injection well bore is introduced into the interior of the electrochemical apparatus. Electrical power is introduced to the electrochemical apparatus such that a portion of the injection water is converted into a product gas, the product gas including hydrogen gas and oxygen gas. The electrochemical apparatus is operated such that the product gas forms product gas bubbles and the product gas bubbles travel into a formation, where the product gas bubbles react with a reservoir hydrocarbon of the formation to form a production fluid that is produced through a production well bore.

Abstract: A method of performing an operation in a well having a conduit includes deploying a tube liner having a lay-flat state into a tubular structure positioned in the well. Fluid is injected into the tube liner to radially expand the tube liner to conform to a tubular wall surface of the tubular structure and thereby provide a protected portion of the conduit within the tubular structure.

Abstract: Methods for treating water comprising dissolved solids in a wellbore include injecting water into a wellbore, where the wellbore has a depth that is sufficient for introducing a hydrostatic pressure that imparts supercritical pressure to water present at a water depth greater than or equal to the minimum depth needed to impart water supercritical pressure. A heating element is inserted into the wellbore to a heating element depth that is greater than or equal to the required depth. Power is transmitted to the heating element causing the heating element to heat water to a temperature sufficient to form supercritical water that causes the dissolved solids to precipitate out of the water as precipitated solids. Water and the precipitated solids are separated and extracted. The heating element includes a microwave antenna and a shell encapsulating the microwave antenna formed from a material that is capable of heating upon exposure to microwave radiation.
