HAWK™ Hydrocarbon Analyzer with Kinetics
The HAWK™ Analyzer provides S1, S2, S3 and TOC data as well as Tmax information. The specially designed instrument has better free petroleum (S1) sensitivity for improved identification of pay in resource plays and adds a new level of sophistication for specialized analysis and integrated interpretation.
Triaxial Rock Mechanics Loading Frame – TerraTek
The TerraTek Rock Mechanics Triaxial Test System is a computer controlled test system designed to simulate in-situ stress and strain for the determination of physical properties of geotechnical core samples. The system simulates actual in-situ conditions and characterizes a test sample’s behavior under those conditions. Axial load, horizontal stress (confining pressure) and pore pressure can all be precisely controlled. In-vessel instrumentation, directly in contact with the rock sample, accurately measures the sample’s response to testing variables.
Shale Interrogator High Precision Petrophysical Characterization
EGI is using high-resolution high-pressure equipment to evaluate the porosity, saturations, and relative permeabilities of tight formations. Called the “EGI Shale Interrogator,” the apparatus is capable of high pressure and high temperature studies that provide accurate measurements useful for petrophysical model calibrations. High precision, low volume pumping capability allows this advanced instrument to provide steady-state data previously not readily available. Finally, the capability to conduct evaluations of liquids- producing formations makes this service unique in the world.
