ABSTRACT:
This is a method of cementing casing under tension. Internal pressure is applied to a casing string set in the borehole after cement has been placed between the casing and the borehole wall. This results in a lengthening of the string. Anchor means are next set in the well wall and pressure released prior to setting of the cement to leave the string with an additional tensile loading.
