Oil Analysis
Industry-Leading Oil Characterization Expertise
At GeoMark Research, our oil analysis services are designed to bring clarity and confidence to exploration, production, and refining decisions. We help customers answer critical questions about oil origin, quality, and compatibility, reducing uncertainty in everything from reservoir evaluation to infrastructure design. Whether you’re classifying oil families, tracing migration pathways, predicting GOR and viscosity trends, or tackling paraffin and asphaltene deposition risks, our integrated approach combines advanced analytical technique such as HRGC, UHRGC, GC-QQQ-MS, and isotopic fingerprinting, to provide the insights you need.
With over 15,000 proprietary oils and 65,000 global benchmarks, our datasets and workflows empower you to benchmark crude quality, validate charge models, optimize separator trains, and prevent costly flow assurance issues.
Comprehensive Answers to Key Petroleum Questions:
-
Where did the hydrocarbons come from?
-
Where did the hydrocarbons go?
-
How did the hydrocarbons change with time?
A Fully Customizable Toolbox to Meet All Your Geochemistry Needs
Tailored Technological Advantage
With the largest toolbox in the industry, GeoMark Research offers a fully customizable protocol and approach based on your needs and questions.
Ultra High Resolution Gas Chromatography
Goes beyond standard HRGC by identifying 133 known compounds and up to 192 peaks, especially C7–C12 hydrocarbon isomers, delivering unmatched resolution to better assess reservoir connectivity and fluid continuity.
Gas Chromatography–Mass Spectrometry (GC‑MS)
Quantifies biomarkers (e.g. steranes, terpanes) to reveal source rock type, maturity, age, and biodegradation.
Triple Quadrupole GC-MS (QQQ / GC-MS-MS)
A proprietary, highly developed technique that quantifies over 215 transition ions in a single run, enabling precise thermal maturity (e.g. VREQ), mobility, NSOq indices, and shines in complex oil-mixing or migration scenarios that single-quad systems can’t resolve.
Carbon Isotopes
Measures the ratios of stable isotopes, such as carbon in oil and gas samples to reveal insights about source rock type, thermal maturity, migration, and mixing. Isotopes provide a powerful, tool for distinguishing between fluids and understanding basin-scale petroleum systems.
SARA (Liquid Chromatography)
Breaks down crude oil into four key components, Saturates, Aromatics, Resins, and Asphaltenes, providing critical insight into fluid composition. This foundational analysis can support fluid characterization, flow assurance, and refining strategy decisions.
API Gravity
Measures the density of crude oil relative to water, offering a quick assessment of oil quality and market value. Higher API values typically indicate lighter, more mature oils that yield greater amounts of refined products.
Compound Specific Isotope Analysis (CSIA)
Measures the carbon isotopic signatures of individual hydrocarbon compounds, allowing precise correlation of oils to their source and detection of thermal maturity, mixing, or biodegradation. This high-resolution technique enhances interpretation in complex petroleum systems where bulk isotopes are less revealing.
