  • Patent number: 6039121
    Abstract: extending into a hot subterranean hydrocarbon-bearing formation containing water at greater than 100.degree. C. The wellbore is divided into three co-extensive passageways; an annulus, and first and second conduits. The annulus is formed within the wellbore between a block at its bottom above the completion intervals and an outlet at the wellhead. The first conduit extends from the formation, through the bottom of the annulus and to an outlet at an elevation intermediate up the annulus. The first conduit is insulated between the bottom of the annulus and its outlet. A second conduit extends between the bottom of the annulus and an outlet at the wellhead. In operation, by producing fluid from the annulus and the second conduit outlets at the wellhead, formation fluid is induced to rise up the first conduit. While the fluid rises, contained water flashes providing steam-enhanced lift.
