Benchtop HTHP (or HPHT) Cement Curing Chamber is designed to prepare oilwell cement specimens for compressive strength test. It is necessary to determine the amount of time required for a cement to develop compressive strength so that drilling/production operations can be resumed as quickly as possible. The target is to design a slurry that can quickly develop compressive strength so as to minimizing the “waiting on cement” time . Benchtop HPHT Curing Chambers provide a means of curing cement specimens under typical downhole temperatures and pressures.
