    This is a Remote Instructor Led Series (RILS) training. The remote classroom delivery is a modality that takes advantage of the instructor led training content, while allowing the same content to be delivered remotely.
    All training sessions will be delivered online with no face-to-face classroom attendance. This class will be delivered in 4 hours sessions over 10 days (including 15 minutes breaks). 

    The course is designed for exploration, production, and development geologists. Lectures show how geochemistry can reduce risk associated with petroleum exploration, how to predict oil quality from inexpensive wellbore measurements, how to identify reservoir compartments and de-convolute mixed petroleum, and how to assess completion problems. It provides guidelines for sample collection and project initiation, how to evaluate prospective source rocks, and how to define petroleum systems through oil-oil and oil-source rock correlation. Case studies and exercises show how geochemistry can be used to solve exploration, production, and development problems while minimizing cost. 

    The lectures are designed to improve understanding of processes that control petroleum quality in reservoir rocks and the bulk, molecular, and isotopic tools that facilitate that understanding. Discussions cover TOC, Rock-Eval pyrolysis, vitrinite reflectance, thermal alteration index, kerogen elemental analysis, geochemical logs and maps, reconstructed generative potential, petroleum generation kinetics, gas chromatography and gas chromatography-mass spectrometry of oil, compound-specific isotope analyses (CSIA) of light hydrocarbons, biomarkers, and diamondoids, and chemometrics to classify oil families, identify compartments, and de-convolute mixtures. 

    In-class exercises illustrate pitfalls to correct interpretations.

    Objectives

    · Identify the elements and processes that control petroleum systems and shale resources and how they are quantified in basin and petroleum system models.

    · Understand the basic concepts of petroleum geochemistry and geochemical measurements, e.g., Rock-Eval pyrolysis/TOC, vitrinite reflectance, GC, GC-MS, GC-MSMS, CSIA, pitfalls.

    · Learn how to collect crude oil and rock samples and how evaluate data quality.

    · Reconstruct the original petroleum generative potential of spent source rock; learn proper procedures to define petroleum generation kinetics.

    · Use biomarkers, isotopes, and chemometrics to correlate oils and source rocks, establish petroleum systems, and assess thermal maturity or biodegradation.

    · Learn how light hydrocarbons, biomarkers, diamondoids, and isotopes are used to correlate oils and assess thermal cracking, thermochemical sulfate reduction, evaporative fractionation, biodegradation, and other reservoir processes.

    · Learn how to evaluate gas and oil geochemistry; identify gas, oil, and water contacts, leakage behind casing; predict oil quality from sidewall cores.

    · Learn how to quantify commingled production and contamination of gas or oil samples.

    · Learn various chemometric methods to interpret large volumes of exploration or reservoir geochemistry data to assign genetic families, define compartments, and deconvolute mixtures.

    · Learn how geochemistry and geomechanics affect unconventional shale gas and shale oil resources.

    · Gain geochemical expertise based on case studies and exercises to allow better communication with colleagues and clients and more efficient exploration/production.
