NOVELTY - The method involves drilling a linear wellbore (130) with a linear segment (104) connected to an arcuate bottom segment (108). Another linear wellbore (132) is drilled to connect to a terminating end of the bottom segment for forming a wellbore loop (100). A thermally conductive tube (140) is placed through the loop, where the linear segment and the latter wellbore are offset distance to eliminate geothermal heat transfer between the linear segment and the latter wellbore. A geothermal transfer grout (148) is pumped into an annulus (146) defined between the tube and a wellbore loop wall.    USE - Method for forming a geothermal well.    ADVANTAGE - The method enables an exchange area to eliminate heat transfer between a supply side and a return side when the supply side and the return side are separated sufficiently far apart such that a fluid medium in the supply side has relatively no impact on the fluid medium in the return side, thus allowing for efficient heat transfer between fluid medium and subsurface environment. The method enables designing the wellbore such that the exchange area placed between the supply side and a return side can become saturated and transfer heat between the supply side and the return side if the supply side and the return side of the tube are not sufficiently offset or separated in the well-bore loop, thus decreasing heat transfer efficiency. The method enables altering configuration of the wellbore loop to avoid underground obstacles to maintain the wellbore loop within a prescribed underground property line.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for exchanging heat between hydraulic fluid and sub-surface environment.
