Abstract: A method of enhanced gaseous hydrocarbons recovery is provided. The method includes placing at least two individual, independently-controllable heating elements aligned opposite one another and in the same location on a production tubing in a wellbore at a gaseous hydrocarbons -producing location of a geological formation to form a permanently-installed array of heating elements. The method also includes heating a portion of the geological formation containing a gaseous hydrocarbons deposit comprising kerogen with a gaseous hydrocarbons formation heating device comprising the permanently-installed array of heating elements, at a temperature sufficient to liberate gaseous hydrocarbons from the kerogen present in the gaseous hydrocarbons deposit and recovering the gaseous hydrocarbons by transporting the gaseous hydrocarbons via the production tubing to the surface. The gaseous hydrocarbons formation heating device comprises a controller configured to control the permanently-installed array of heating elements.

Abstract: A thermochemical engine that includes a reaction chamber having a nitrite source inlet, an ammonium source inlet, and a gas outlet, and a gas-driven energy transducer coupled to the reaction chamber such that a gas produced in the reaction chamber moves the gas-driven energy transducer in a process of exiting the reaction chamber via the gas outlet. The thermochemical engine is configured to produce the gas under pressure by reacting in the reaction chamber a nitrite source comprising a nitrite ion and an ammonium source comprising an ammonium ion in the presence of water at a reaction temperature of 50 to 150° C.
