Each of these core sample analysis techniques, performed in GeoMark labs, provide useful data for calibrating models, constraining properties, and impacting business decisions based on subsurface data.
TOC and Programmed Pyrolysis
The following data are provided: organic enrichment, kerogen type, source rock generative capacity, source rock quality, calibration of geological-geochemical and petrophysical models, existing volatile fraction, geochemically based original oil-in-place, kinetic modeling for basin modeling constraint (generative capacity and expulsion), seal effectiveness, thermal maximum/thermal maturity, and lithological model calibration.
Thermally or Chemically Extracted Fluids and Analysis
The following data are provided: Geochemical fingerprinting, time-lapse geochemistry calibration, maturity, charge and migration understanding, fluid loss quantification, comparison of mobile versus immobile compositions/fluid types/flavors to produced fluid
TruSat Rock Properties
The following data are provided: grain volumes, total porosity, dual retort oil, and water saturations, including free versus bound fluid volumes (a unique thermal and solvent-based extraction technique). (Refer to the link below to access the diagram.)

NMR T1/T2 acquisition and 2D map capability
- T2 distributions can be utilized for fluid-filled pore body quantification and understanding.
- T1/T2 results can be utilized for potential fluid typing and understanding of lost fluid fraction.
Open and closed retort capability
- Assess the free versus bound water results (i.e. water partitioning). This can be compared to NMR results.
- Mobile versus immobile hydrocarbon fraction (i.e. hydrocarbon partitioning).
Geochemical integration of TOC and programmed pyrolysis data (can be complimented by fluid property analysis)
- Differentiates the thermally versus chemically extracted results for an understanding of mobile versus immobile organic matrix components.
- Offers TOC calibration for all subdisciplines.
- Provides thermal maturity (Tmax) understanding, as well as volatile fluid fraction (S1 mg/g) versus remaining source rock potential constraint (S2 mg/g).
