Abstract
A method for enhancing the production of hydrocarbons such as oil from a wellbore extending into a hydrocarbon reservoir. The method includes identifying a fissure within the hydrocarbon reservoir that is in fluid communication with the wellbore and injecting calcium brine solution and liquid carbon dioxide into the well bore so that the calcium brine solution may react with the carbon dioxide to precipitate calcite and substantially prevent fluid flow through the fissure. The method may enable selected fissures to be sealed thereby enhancing the overall productivity of the well. Other applications of the calcite precipitation method are also disclosed.

Abstract
A method of repairing a well is provided. The method includes injecting a brine solution into the well, injecting carbon dioxide into the well, and reacting the brine solution in the reservoir rock with the carbon dioxide to form calcite such that calcite precipitates into the desired flow path between a cold well and a hot well to effectively repair short circuits within the EGS reservoir.
