1. A method of creating effective flow conduits between wells in geothermal reservoirs comprising:
providing a wellbore wherein the wellbore is positioned in a formation, wherein the formation comprises both a non-fractured portion and a fractured portion, wherein the wellbore comprises a plurality of cementing sleeves and a plurality of flow control/tensile-splitting sleeves in the fractured portion, and further wherein the wellbore comprises a lateral, wherein the lateral comprises a plurality of non-cemented sections and a plurality of cemented sections, and further wherein the wellbore comprises a plurality of casings, wherein the plurality of casings comprise a plurality of casing joints;
creating a plurality of cement plugs, wherein each of the cement plugs is positioned between more than one of the cementing sleeves;
creating a propped tensile-split conduit in one of the cemented sections, wherein the propped tensile-split conduit is located in the non-fractured portion, and further wherein the propped tensile-split conduit is generated by injecting fluid through the flow control/tensile-splitting sleeves;
installing a circulation sleeve near the heel of the wellbore, wherein the circulation sleeve is employed as a conduit for returned circulation fluids in the annulus of the wellbore;
installing a float shoe; and
installing a plurality of standoff band turbalizers;
wherein each of the plurality of cementing sleeves is installed between two of the plurality of casing joints in one of the plurality of non-cemented sections, and further wherein each of the plurality of cementing sleeves is controlled between an open and a closed position;
wherein each of the plurality of flow control/tensile-splitting sleeves is controlled between an open, closed, or choked position.
