SOURCE ROCK EVALUATION

Objectives 

Determine  the  richness,  type  (oil  or gas)  and thermal maturity of sedimentary organic matter in rock samples to evaluate as a potential source of petroleum hydrocarbons and CBM producibility

Samples

Shales, carbonates, and coals from outcrop and well samples. Well samples may be cuttings, sidewall cores or conventional cores.

CRUDE OIL AND OIL SEEP CHARACTERISATION

Objectives

  • Determination of Composition of Natural Gases: Hydrocarbon and Non-hydrocarbon
  • Determine oil quality
  • Identify source rock type, level of thermal maturity, and nature of any alteration processes
  • Make oil-oil, oil-condensate, and oil-seep  correlations
  • Define reservoir continuity
  • Make oil-source rock correlations

Samples

  • Subsurface crude oils and condensates
  • Surface oils, condensates, and seeps
  • Oil impregnated reservoir rock in subsurface and in outcrops

Analyses

  • API Gravity
  • Sulfur content
  • Whole Oil Gas Chromatography
  • Liquid Chromatographic Separation
  • GC-MS of Saturate and Aromatic hydrocarbon fractions
  • Carbon Isotope of Saturate and Aromatic hydrocarbon fractions

Interpretation and Report

Provides an assessment of the source organic matter type and maturity at generation, depositional environment, evaluation of any  alteration processes, and possibly geologic age.  If multiple oils are evaluated, oil-oil correlation and reservoir continuity can be assessed.

 

GAS EVALUATION

Objectives

  • Determination of Composition of Natural Gases: Hydrocarbon and Non-hydrocarbon
  • Origin   of   Hydrocarbon  Gases:  Biogenic, Thermogenic or Mixed
  • Organic Source Type and Thermal Maturity of Hydrocarbon Gases
  • Origin of Non-hydrocarbon Gases, if present in sufficient quantities

Analyses

  • Hydrocarbon  Gas   Analysis  (C1-C5+)
  • Non-hydrocarbon Gas Analysis (CO2, N2)
  • Stable Gas Carbon Isotope ratios on C1, C2, C3, C4
  • Stable Hydrogen Isotope ratio on C1
