Total Organic Carbon Content Determined From Well Logs
SPE Formation Evaluation, 1988Summary Total organic-carbon (TOC) content present in potential source rocks significantly affects the response of various well logs. This paper discusses and illustrates well-log anomalies caused by TOC as observed on various wireline measurements, including resistivity (or conductivity), acoustic, nuclear (density and neutron), gamma ...

The Isiokpo Oil-Pipeline Leakage: Total Organic Carbon/Organic Matter Contents of Affected Soils
Chemistry & Biodiversity, 2005The environmental impact of the 1997 leakage of the high-pressure crude-oil pipeline at Isiokpo in the Niger Delta in the southeast of Nigeria was evaluated, with particular reference to total-organic-carbon (TOC) and total-organic-matter (TOM) contents of soils within the vicinity of the oil spillage.

<p>Soil organic carbon (SOC) content is the major indicator used for soil quality evaluation because provides several ecosystem functions. However, SOC content does not allow to understand the soil potential to deliver the key ecosystem functions because most of soil processes are linked to soil biota.

Predict Continuous Total Organic Carbon Content by Support Vector Regression
81st EAGE Conference and Exhibition 2019, 2019Summary Total organic carbon (TOC) is a significant factor to evaluate hydrocarbon potential of the unconventional reservoir, which is difficult to obtain the continuous and accurate prediction result by traditional methods. Support vector machine is an efficient supervised learning artificial intelligence algorithm, which performs well in ...

Organoclay Sorption of Benzene as a Function of Total Organic Carbon Content
Journal of Colloid and Interface Science, 2002The sorption of benzene to bentonite, activated carbon, and two organo-clays synthesized with the quaternary ammonium organic cations hexadecyltrimethylammonium (HDTMA) and benzyltriethylammonium (BTEA) was quantified as a function of total organic carbon content.

Predicting Total Organic Carbon Content of Soils from Walkley and Black Analysis
Communications in Soil Science and Plant Analysis, 2014Globally, there is problem of computing soil carbon stock because the Walkley–Black method gives only an approximation of soil organic carbon content. Until now, no universal relationship between Walkley–Black carbon (WBC) and total soil organic carbon (TOC) has been developed that could be applicable in all kinds of soil.

ORGANIC CARBON AND TOTAL NUTRIENT CONTENTS OF INCEPTISOL UNDER LONG-TERM FERTILISATION
Madras Agricultural Journal, 1996Beneficial role of FYM in increasing the organic carbon content and total nutrients of the soil was evidenced when applied with inorganics (NPK). Application of NP fertilisers increased the nutrient status when compared to application of N alone. Regarding depth all the nutrients got decreased as the depth increased.

Determination of Total Organic Carbon Content in Shale Formations With Regression Analysis
Journal of Energy Resources Technology, 2018By correcting both the positive and negative ΔlogR separation resulting from the resistivity in organic-deficient shales, the traditional ΔlogR correlation is modified, validated, and applied to determine the total organic carbon (TOC) content in shale formations.

Total Organic Carbon Content in Aqueous Samples Determined by Near-IR Spectroscopy
Applied Spectroscopy, 1999We describe the application of near-infrared spectroscopy with partial least-squares (PLS) multivariate calibration to determine the total organic carbon (TOC) content of aqueous organic samples. We demonstrate a standard error of precision of approximately 0.50 mg/mL for the TOC content in aqueous organic mixtures of Na3HEDTA, Na4EDTA, and acetone ...
