High-Temp Triaxial Analysis
We are home to one of the few high-temp full core triaxial testing apparatus in Calgary, AB.
During a triaxial analysis, the caprock is placed in a special steel cell that has pressure applied to the side of the sample to represent the effects of the samples being buried underground. The samples are then compressed and the physical properties of the samples are determined. Additionally, the rocks are failed to determine shear strength.
Samples need to be run cold as well as hot since part of the caprock is heated by steam. The caprock core testing must be done correctly to represent true conditions for oilfield use. Therefore, it is imperative that the samples be processed by a lab that specializes in testing caprock core for steam-assisted gravity drainage (SAGD) and cyclic steam stimulation (CSS) applications.
Lab test data can be correlated and combined with other information collected, for example mini-frac results and logs, to confirm the caprock’s physical properties.
