The Benchtop HTHP (or HPHT) Cement Curing Chamber is designed to prepare well cement specimens for compressive strength tests. 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 goal is to design a slurry that can quickly develop compressive strength so that the “waiting on cement” time may be minimized. The OFITE HPHT Curing Chambers provide a means of curing cement specimens under typical downhole temperatures and pressures.
