Geochemical Characterization of Kazhdumi Source Rock in the Khaviz Oil Field, Southwest of Iran, Using Rock-Eval Pyrolysis
The Khaviz oil field located in Dezful embayment is one of Iran’s southwest oil fields. In this study, a total of 28 cutting samples from Kazhdumi formation (well No. KZ1, Khaviz oil field) were subject to geochemical investigation using Rock-Eval pyrolysis for the first time. The results of pyrolysis indicated that Kazhdumi source rock has significant hydrocarbon production potentiality and al...
متن کاملCan Rock - Eval pyrolysis assess the biogeochemical composition of 1 organic matter during peatification ?
Understanding the responses of soil organic carbon to an increase in global temperature is crucial to estimate potential feedbacks on global warming. In such a context, Rock-Eval pyrolysis has been recently proposed as a screening tool to investigate soil organic matter (SOM) chemistry and vulnerability. In order to test the validity of Rock-Eval as an indicator of SOM chemistry and of OM trans...
متن کاملEarthworms and Soil Pollutants
Although the toxicity of metal contaminated soils has been assessed with various bioassays, more information is needed about the biochemical responses, which may help to elucidate the mechanisms involved in metal toxicity. We previously reported that the earthworm, Eisenia fetida, accumulates cadmium in its seminal vesicles. The bio-accumulative ability of earthworms is well known, and thus the...
متن کاملImproved Performance of Soil Microbial Fuel Cell by Adding Earthworms
Soil microbial fuel cells (SMFCs) are expected as an application to produce sustainable energy. Here, we focused on soil ecosystems, specifically the earthworms which are known to improve soil-fertility by degrading fallen leaves or plant litter. The aim of this study was to investigate the effect of earthworm on power generation of the SMFC. The maximum power density and the internal res...
متن کاملSource Rock Evaluation and Maturity Levels of the Rudeis Formation, Northern Gulf of Suez, Egypt, Using Well Log Analysis and Rock-Eval Pyrolysis
Gamma-ray, density, sonic, resistivity and neutron are the commonly used wireline logs to identify and quantify source rocks. Several models were developed to use the conventional wireline logs for evaluating the thermal maturity of the source rocks and calculating the total organic carbon (TOC) content. Application of Schmockr and Hester [1] approach with some required modifications for the Ru...
