In situ combustion process for the recovery of liquid carbonaceous fuels from subterranean formations

TL;DR: In this paper, an integrated in situ combustion process for producing underground carbonaceous deposits is described, in which the resulting flue gas of low heating value is combusted over an oxidation catalyst at substoichiometric conditions.
Patent

Method of stimulation of a subterranean formation

TL;DR: In this article, the authors proposed a method of widening or extending fractures in a underground formation which intersects a wellbore to enhance the flow of fluids from the formation, by introducing an explosive gas comprising a gaseous oxidizer and a gas fuel and optionally a quantity of inert gas into at least one fracture intersecting the well-bore.
Patent

Stimulating subterranean formations in the open hole

TL;DR: In this paper, a thermal ignitor is placed in the well and fuel and oxidizer are either pumped or poured into the well to generate high pressure combustion products, which rapidly flow into the formation creating the fractures.
Patent

Utilizing electrically actuated explosives downhole

TL;DR: In this article, an electrically controllable explosive material (EIECEM) is controlled by limiting the duration of excitation at an electrical source, for example, the duration that an electric source provides an electrical charge, electrical current or electrical signal.
Patent

System and method of delivering stimulation treatment by means of gas generation

TL;DR: In this article, the authors used electrically ignitable propellant to generate gas downhole that can be used to generate or enhance fractures, allowing for the control of the amount and location of generated gas.

Geological formation heating

TL;DR: In this paper, a borehole terminates by generating a series of explosion waves at the bottom of the borehole, where fuel and oxygen (air) are continuously passed into the bore hole, the oxygen and fuel continuously mixed in the vicinity of the end of the Borehole, and the explosive mixture intermittently ignited so as to generate heat and shock waves which pass to the surrounding formation.

Method of fracturing a natural gas bearing earth formation

D Munson
TL;DR: In this paper, a method of fracturing a natural gas bearing earth formation penetrated by a well bore by introducing a charge of oxygen into the well bore and into the producing formation in such volume as to produce an explosive mixture of natural gas-oxygen in a portion of the formation extending about and from the well-bore and igniting the mixture to generate an explosion of the natural gasoxygen mixture in such portion, thereby causing fracturing of the Formation.

Thermal detonation energy-initiatable blasting caps, and detonation system and method

TL;DR: In this paper, a nonelectrically initiated blasting cap containing an initiation charge ignitable in response to action of thermal detonation energy of an explosive gas mixture, including conduit means for emplacing a confined stream of the explosive gas in detonating position in the blasting cap for the responsive ignition, is provided.
