Abstract: A thermal reach enhanced geothermal wellbore is provided. The geothermal wellbore includes a wellbore extending from a topside surface to a target location in a formation. The geothermal wellbore further includes a plurality of fissures that distally extend from the target location into the formation and that are at least partially filled with a compacted high-thermal k material. The compacted high-thermal k material terminates on a proximal end at the target location of the wellbore and is thermally coupled to a high-thermal conductivity grout or slurry through which heat is conducted to a working fluid that is contained in a closed loop working fluid conduit embedded in the grout or slurry.

Abstract: A method and system for enhancing petroleum production are provided, in which a fracturing operation can be conducted in a formation through a string and then petroleum is displaced from the fractured formation by selectively injecting fluid into selected fractures in the formation while other non-selected fractures remain without fluid injection. The injected fluid flows out into the fractured formation and enhances recovery from the non-selected fractures. Petroleum is selectively collected from the non-selected fractures.

Abstract: The present disclosure provides a self-generating heat process for in-situ converting medium-low mature and organic-rich shale, and relates to the field of in-situ mining of medium-low mature shale rich in organic matter, the self-generating heat process mainly comprises the following steps: locally preheating the vincinity of an injection well of medium-low mature and organic-rich shale formation with well-reformed reservoir and injecting ambient temperature air into the preheated formation to excite and establish a chemical reaction zone composed of a residue zone, an autogenous heat zone, a thermal cracking zone and a preheating zone. Heat is released by oxidation reaction of residues generated after kerogen thermal cracking, so as to realize convection heating of medium-low mature and organic-rich shale formation. Oil and gas products generated from kerogen thermal cracking enter production wells through fractures and are lifted to the ground surface. Because the in-situ oil shale conversion technology only needs local preheating the vincinity of the injection well and only a small amount of external heat or combustibles injection, the related cost is low.
