Humble Geochemical Services

Analytical and Interpretive Services in Organic Geochemistry


Humble Geochemical Services offers complete analytical and interpretive services in the field of organic geochemistry. We feature state-of-the-art instrumentation, which provides the highest quality analytical data. These services includes rock and oil analyses ranging from screening analyses such as total organic carbon (TOC),

Rock-Eval, and vitrinite reflectance to detailed services such as high-resolution gas chromato-graphic fingerprinting and biomarker analysis. In addition we offer highly specialized services in source rock decomposition (kinetics) and yields analyses as well as other specialty analyses.

In petroleum systems analysis organic geo-chemistry is utilized to high-grade prospects or plays by assessing the likelihood of hydrocarbon charge


Geochemical analyses of rock samples provides basic information to assess their source potential, oil or gas proneness, and thermal maturity.

Oil analyses can be used to infer petroleum systems and source rock maturities in a basin even when rock samples are not available

Reservoir continuity studies using geochemistry are inexpensive to complete and there is no lost production due to shutting-in a well. In place of a single PVT test, 40-50 oils from wells across a field could be analyzed using Humble’s reservoir oil fingerprinting (ROF) technique.

Figure 4. Reservoir continuity can be assessed by simple ROF analysis rather than expensive PVTs

From 6 oils from the 2 horizons in each well above, the following questions could be addressed:

Is the fault sealing or leaking?
Are horizons “A” and “B” vertically and horizontally continuous?
Does sand “B” pinch out?

ROF can be used to evaluate commingled production and is especially effective with a historical oil collection.


Key to Good Service...

is defining the questions to be answered and designing an analytical program to answer those questions. We can help you design a geochemical program to meet your objectives.
