Distinct Advantages

  • PHYSICALLY measures BOTH Hydrocarbon and Water (vs. measured water with assumed oil density)

  • Closed Retort Design Virtually Eliminates Light-End HC Loss

  • CORRECTS for Fluid Loss Due to Laboratory Crushing

  • Fully Integrated Workflow can CORRECT for fluid loss from Coring, Transport, and Sample Prep

  • Includes Porosity Measured via Three Independent Methods

  • Step-wise THERMAL and CHEMICAL Extraction

  • Partitions Mobile vs. Less Mobile Hydrocarbon Components

  • Fluids Quantified by Visual Imagery (Standard Deliverable)

  • Integrated Geochemistry Data including Programmed Pyrolysis and HRGC of As-Received and Post-Extraction Fluid


Superior Porosity and Saturation Quantification

Drastically Improves Subsurface Models and Predictions of Producibility

Traditional (Crushed) & Intact Workflows Available

The TruSat workflow was developed by first attempting to understand the competing retort and extraction processes, followed by rigorous experimental standard trials conducted to determine needed improvements. The result was the development and application of a workflow that is unique and more accurate than any other method practiced in the oil and gas laboratory market to date. TruSat greatly improves the accuracy of porosity and saturation data through increased process controls, and the integration of multiple independent tools and methods, including as-received nuclear magnetic resonance (NMR) and geochemistry (TOC/HAWK), while also allowing for customization of analytical programs. The unique workflow uses a dual-retort process to quantitatively measure total, free, and bound water, alongside the accurate hydrocarbon saturation measurements with a closed retort collection efficiency average of ~99%+. Figure 1 represents this workflow in two forms that can be used to fully assess the rock and fluid volumetric space.


Quantified Fluid Loss is Now Possible

Correct/quantify the impact of the lost fluid during coring/collection, transport, sample prep.


Fully Integrated Pyrolysis Data Included with Every Sample.

  • Better Quantification of Volatile Fluid Presence

  • Ability to Break Down the Mobile vs Less Mobile/Immobile Fractions

  • Understanding of the Organic Matter Contribution to Hydrocarbon Presence

  • Differentiate thermal and chemically extracted fluids – understand mobile & immobile organic matrix components TOC calibration for all subdisciplines

  • Thermal maturity (Tmax), and volatile fluid fraction (S1 mg/g) vs. remaining source rock potential (S2 mg/g)

  • Improved constraint and understanding of stratigraphy

  • Partition both water and hydrocarbon phases for improved oil-in-place assessment

  • Bridge potential challenges among geological, geochemical, petrophysical and engineering applied learnings and concepts

  • Combine with PVT data to improve economic assessments directly affecting business decisions

Sample Requirements

Required Sample Mass & Dimensions

  • Minimum: ~80g

  • 100-120g (ideally) for the Crushed Rock Workflow

  • Intact Workflow Requires 1 Plug w/minimum dimensions 1×1/1.5

Best Suited for:

  • Core Plugs, RSWC, Pucks, 2/3 Butts, ‘chunks’

  • Starting material must be intact

Preservation Required?

  • Fresh cut, wrapped in plastic/foil

  • Chilled transport When Possible

  • Wax preservation is ideal

  • Non-preserved samples will be run at Operator’s discretion
