TITLE Petroleum Geochemistry and Microbiology

 
UM LEVEL 05 - Postgraduate Modular Diploma or Degree Course

 
MQF LEVEL 7

 
ECTS CREDITS 5

 
DEPARTMENT Geosciences

 
DESCRIPTION - Origin of petroleum, abiogenic & biogenic sources;
- Composition of petroleum, types of oils and their characteristics;
- Kerogen - analysis, maturity and type;
- Diagenesis, catagenesis and metagenesis;
- Principal zone of oil generation, thermal history, vitrinite reflectance;
- Rock-Eval maturity parameters;
- Basin modelling;
- Biogenic and thermogenic gas;
- Isotopic characteristics of main gas types;
- Microbiology & petroleum nutrient;
- Conversion of petroleum hydrocarbons into microbial products;
- Sampling, detection and analysis;
- Geochemical & microbiological surveys.

Study-unit Aims:

The study-unit aims to provide the knowledge of the chemical and microbial processes that lead to the alteration of organic matter in rocks and the generation and degradation of petroleum in order to develop an understanding of basin modelling and maturity evaluation needed to assess basins for their petroleum type and potential. The unit also provides knowledge of the of how these chemical and microbial products can be used in the exploration for petroleum.

Learning Outcomes:

1. Knowledge & Understanding:

By the end of the study-unit the student will be able to understand the basic chemistry of petroleum generation, types, the roles played by temperature and basin history on such generation, the nutrition value of petroleum to bacteria and the use of such chemical and microbiological analysis of the ground to search for accumulations of petroleum.

2. Skills:

By the end of the study-unit the student will be able to:
- Conceive and formulate petroleum geochemical and microbiological hypotheses;
- Plan geochemical and microbiological evaluation programmes and surveys;
- Select and use appropriate geochemical/microbiological techniques and procedures in a variety of situations;
- Research and synthesise geochemical/microbial information from various sources;
- Analyse, evaluate, interpret and integrate chemical and microbial data in basin modelling and maturity evaluation to determine petroleum type and potential;
- Interpret geochemical/microbiological surveys of an area for its petroleum potential.
