Abstract
This specification discloses a technique of providing a wellbore that is extended along a track from the surface of the earth and penetrates and passes through a subsurface mineral-bearing formation a plurality of times. The wellbore is initially extended from the surface of the earth into the earth's crust in essentially a vertical direction and then is deviated toward the horizontal and extended to pass through the subsurface mineral-bearing formation from top to bottom at an oblique angle. The wellbore is then further deviated and extended along a track in an upwardly direction such that it again penetrates and passes through the subsurface mineral-bearing formation, this time from bottom to top. The wellbore may then again be deviated and extended along a downward track to again penetrate the formation from the top.
