    ROCK EVAL PYROLYSIS AS A TOOL FOR CHARACTERIZATION OF ORGANIC MATTER IN SOIL SAMPLES Tünde NYILAS1, Marianna IMRE2 1Department of Mineralogy, Geochemistry and Petrology, Faculty of Science and Informatics, University of Szeged, HUNGARY 2Department of Geology and Paleontology, Faculty of Science and Informatics, University of Szeged, HUNGARY. Kerogen, the major organic component of sedimentary rocks, is commonly analyzed by Rock-Eval pyrolysis. Plotting the data on a graph of S[2] vs. total organic carbon (TOC) and determining the regression equation is the best method for determining the true average hydrogen index and measuring the adsorption of hydrocarbon by the rock matrix.

    he Source Rock Analyzer (SRA) pyrolyzes rock samples to deliver accurate source rock and reservoir data, such as total organic carbon (TOC), thermal maturity (Tmax), free oil content (S 1), and source potential (S 2). The SRA is a lab services instrument as well . Source rock richness is determined by measuring the total organic carbon (TOC) present in a rock. The two most common techniques of analyzing a rock for TOC are Rock-Eval pyrolysis with TOC and the LECO tional well logs can also provide information for evaluating interval richness.

    PSModified Method and Interpretation of Source Rock Pyrolysis for an Unconventional World* Robert R. King1 Search and Discovery Article # ()** Posted Octo *Adapted from poster presentation given at AAPG Annual Convention and Exhibition, Denver, Colorado, May 31 . Rock-Eval pyrolysis is used to rapidly evaluate the petroleum-generative potential and thermal maturity of rocks. Accurate conclusions require programs every ft ( m), understanding of interpretive pitfalls, and supporting data, such as visual kerogen, vitrinite reflectance, and elemental analyses.

The remaining deficit may be explained by the so-called"mineral matrix effect", which is known to decrease the quan­ tities of hydrocarbons expelled from the sample during pyrolysis (Espitalie et aI., ).

Comparative pyrolysis has been applied to 53 samples of various origin and bitumen content. The. Rock-Eval pyrolysis is used by petroleum explorationists to measure the quantity, quality, and thermal maturity of organic matter in rock samples (Peters and Cassa, ).Combined with total organic carbon (TOC) measurements, this is the most rapid and cost effective screening method for large numbers of samples.

3 / 23 pyrolysis (CO and CO2 pyrolysis curves), () CO and CO2 produced during oxidation (CO and CO2 oxidation curves). The sixth curve in Figure 3 is the superposition of CO and CO2 curves and is very useful for a rapid visualization of the presence or absence of carbonate in the sample.

An important caveat in this study is that the pyrolysis and oxidation of mineral carbon fractions automatically measured by Rock–Eval analysis (portion of S3, S3CO 2 and S5CO 2 /S5CO) was converted into an organic carbon quantity since our samples contain no.

Every oil or gas play originates from source rock. The viability of each play—conventional or unconventional, oil or gas—depends on its source rock. Without this source of petroleum, all other components and processes needed to. A total of 36 samples were collected and analyzed using Rock-Eval pyrolysis.

The screening results which are summarized in table V and graphically illustrated on figures V-1, V-2 and V-3 indicate that the Bou Dabbous formation can be rated as having fair to good TOC contents ranging from to % (Mean TOC value: %).

Rock-Eval®/TOC data are presented for washed cuttings samples at 10 m intervals in the Northrock et al. East MacKay I well (64° 46' " N latitude; ° 43' " W longitude) located in. The pyrograms in Fig. 4 show the results from Rock-Eval pyrolysis determinations on the same sample in fresh state and after cleaning with organic solvents (chloroform/methanol v/v) for 24 h.

This rock comes from a larger set of samples collected for source-rock analysis. This is achieved through transient pyrolysis of the samples up to °C followed by combustion up to °C, with hydrocarbons, CO and CO2 measured during the thermal decomposition of both OM and carbonate ate minerals with low thermal cracking temperatures, such as siderite.

Pyrolysis, by definition, is the thermal decomposition of materials at elevated temperatures in an inter atmosphere. In layman’s terms. It’s heating in the absence of oxygen. In the oil and gas industry, the most popular tool that we use to perform TOC on a sample is Rock-EVAL pyrolysis.

Guidelines for Rock-Eval analysis of recent marine sediments François Baudina, Jean-Robert Disnarb, Anabel Aboussoua, interpreting Rock-Eval pyrolysis data from recent marine sediments. Material and methods The samples were collected from different parts of the deep sea turbiditic system of the.

Rock-EvalTM/TOC measures three types of products, hydrocarbons (HC), carbon dioxide (CO2) and carbon monoxide (CO) evolved during both anoxic pyrolysis and oxidative pyrolysis. Older versions of the device such as Rock-Eval 2 had only a CO2 detector and they measured only HC and CO2.

It is a useful screen for recognizing sources and. Seven samples of Eocene fine sediments collected from East Ketungau Basin were analyzed by Rock-Eval pyrolisis and three samples for biomarker to evaluate their hydrocarbon potential. The Rock-Eval pyrolisis result of Mandai Group shows that TOC value of this facies ranges from % to %, Potential Yield (PY) between and mg HC.

Sedimentary rock samples were taken from Triassic intra-platform basin (Rezi, Vérhalom) and from Pula oil shale (West-Hungary).

The Rock Eval data of the soil and rock samples were determined with Delsi Oil .Rock-Eval pyrolysis [1] has been a widely used method in organic geochemistry for examining the oil and gas potential and maturity of different ancient and recent sediment samples [].

The method was extended to biomass samples in the paper [9]. Besides, a software OPTKIN was developed [10] for description of pyrolysis kinetics using the Rock.
