Wettability Testing

Knowledge of the wettability of a reservoir rock is a key factor for determining oil recovery mechanisms and making estimates of recovery efficiency. PTS offers industry-standard Amott and Modified USBM wettability tests, including the USBM test at elevated temperatures. For samples that have been subjected to weathering, PTS offers sample restoration in crude oil at reservoir temperature.

Pore Volume Compressibility

Hydrostatic pore volume compressibility testing is a routine offering for 1-in., 1.5-in. and 2-in. diameter samples and pressures up to 10,000 psi. Cyclic compression and decompression tests, as well as failure point determination tests, are also available. PTS has in-house capabilities to perform uniaxial or triaxial stress testing. Advanced geomechanical determinations are also available (see Geomechanical Studies).
