Whole Oil Analysis

Whole Oil Analysis using high resolution chromatography

High resolution chromatography delivers easily understandable, and actionable oil lab data

Whole Oil Analysis is primarily used as a tool to get an in depth look at a specific oil. This information can then be interpreted and compared with other oils in a wide range of applications. The main components of a whole oil analysis are the hydrocarbon fingerprint, biomarker analysis, and light hydrocarbon analysis.

Using high resolution chromatography Zedi can detect changes that affect the evaporative fractionation (or vapor phase fractionation of crude oil), maturation, water washing and bio-degradation that can bring you questions of reservoir continuity. Our Whole Oil Analysis will also determine how many effective source rocks exist in a given area.  This easily provides you the data you need to know for input for volumetric calculations and development geology.


Whole Oil Analysis with high resolution chromatography Technology driven accuracy

We use multiple GCs to get the best resolution possible from both the light (C4-C10 fraction), and heavy (C10-C40+ fraction) to give you the most valuable results.

We also offer a “calibrated” whole oil analysis, which is also more accurate than how most lab perform these test. It's a slightly more intensive test, but with higher quality results.


Whole Oil Analysis with high resolution chromatography Whole oil Analysis verses C10 hydrocarbon analysis

The most common liquid hydrocarbon analysis is a C10 BTEX analysis. This test provides you with compositions for C1-C10 hydrocarbons including BTEX components. In these reports compounds that are not of interest are lumped into groups and not identified individually. For example, the heptanes group contains compounds like 3,3-Dimethylpentane and 2,3-Dimethylpentane lumped together.

In a whole oil analysis groups are separated and each compound is displayed individually. While this kind of detail this isn’t required for most permitting or general analysis, it can be used as a powerful tool to determine various properties of the oil. Some of these properties can include: maturity, depositional environment, and similarities between oils. On top of this the whole oil analysis covers a wider range of hydrocarbons, C1-C41, and it includes an analysis of isoprenoid biomarkers in the oil.


Whole Oil Analysis with high resolution chromatography Common applications

  • Comparing two oils of unknown origin
  • Addressing problems of reservoir continuity
  • Detecting alteration affects such as evaporative fractionation, maturation, water washing, and biodegradation
  • Classifying oils into genetic families
  • Determining how many effective source rocks exist in a given area
  • Proposing migration pathways from current areas to new prospects or plays
  • Providing input data for volumetric calculations
  • Providing data for development geology


Whole Oil Analysis with high resolution chromatography Components of Whole Oil Analysis

To make sense of the hydrocarbon fingerprint, biomarkers, and light hydrocarbon analysis Zedi will provide you with various parameters based on the composition of the oil. These parameters include: Thompson, Mango, Halpern, and other various parameters.

Hydrocarbon fingerprintHydrocarbon Fingerprints

An integral part of a whole oil analysis the hydrocarbon fingerprint. The “fingerprint” term refers to the unique C1-C41 profile that oil from different genetic sources will have. However, fingerprint shape alone is not enough to make asssumptions about similarties between oils. Oils may have similar C10-C41 portions, but closer examination of biomarkers and light hydrocarbons may unearth fudamental differences between the oils.

Biomarkers  Biomarkers

Biomarkers can refer to a widre range of compounds in crude oil, but the whole oil analysis focuses specifically on the isoprenoid category of biomarkers. Biomarkers will appear in naturally in all oil, and by analyzing biomarkers based on well researched methods the depositional environment can be determined.

Light Hydroarbon Analysis  Light Hydrocarbon Analysis (heptanes)

Based on the work of Dr. Frank D. Mango, light hydrocarbon analysis has become essential in oil to oil comparisons. As crude oil degrades, a unique profile of heptanes arises, which can be used to compare oils. In our light hydrocarbon analysis portion of the whole oil report we proved you with a detailed report of the heptanes composition.
