US Classification:

166293, 166292, 166309, 106672, 106678, 106713, 106725, 507202, 507269, 507271

Abstract:

The present invention provides improved lightweight well cement compositions useful for performing a variety of cementing applications in subterranean formations and particularly for cementing conductor pipe in offshore wells. A preferred cement composition basically comprises a hydraulic cement, an effective amount of an iron salt selected from the group of ferric chloride, ferrous chloride or mixtures thereof to reduce the transition time of the composition, sufficient water to form a pumpable slurry, an effective amount of a foaming additive for producing a foamed slurry, and sufficient gas to foam the slurry.

Assignee:

Halliburton Energy Services, Inc. - Duncan OK

International Classification:

E21B 33/14

US Classification:

166277, 166292, 166293, 106805, 106810, 106823

Abstract:

The present invention relates to subterranean cementing operations, and more particularly, to methods of cementing in subterranean formations using cement compositions that autogenously cure voids that may form in such cement compositions. In one embodiment, the present invention provides a method of cementing in a subterranean formation penetrated by a well bore comprising the steps of: placing a cement composition into the well bore, wherein the cement composition comprises a first cementitious component having a first set time and a second cementitious component having a second set time that is delayed relative to the first set time of the first cementitious component; allowing the first cementitious component to at least partially set; and allowing the second cementitious component to set after a delay period.
