A method for improving hydrocarbon flow from a consolidated, tight reservoir rock having authigenic clay cementation includes thermally heating the reservoir rock in-situ surrounding a production well to change the mode of occurrence of clay cements within the rock so as to enhance reservoir permeab
A method for improving hydrocarbon flow from a consolidated, tight reservoir rock having authigenic clay cementation includes thermally heating the reservoir rock in-situ surrounding a production well to change the mode of occurrence of clay cements within the rock so as to enhance reservoir permeability and carrying out rapid flowback into the production well.
A method for improving hydrocarbon flow from low permeability, tight reservoir rock having authigenic clay cementation surrounding a well penetrating a hydrocarbon-bearing reservoir, comprising the steps of: a) injecting a known volume of a combustible fluid through said well into said low permeabil
A method for improving hydrocarbon flow from low permeability, tight reservoir rock having authigenic clay cementation surrounding a well penetrating a hydrocarbon-bearing reservoir, comprising the steps of: a) injecting a known volume of a combustible fluid through said well into said low permeability, tight reservoir rock surrounding said well, said known volume of combustible fluid being sufficient, upon in-situ combustion, to cause a change in the structure of the clay cement within the pores of said reservoir rock without changing the fundamental structure of said reservoir rock, b) initiating combustion within said tight reservoir rock by means of a downhole igniter and c) terminating combustion when all of said known volume of combustible fluid injected into said reservoir rock has been ignited and spent.
