Petroleum Geology & Log Analysis
The course petroleum geology and basic log analysis provides the overview of petroleum geology and its different dimensions including various rock types, occurrence and abundance. The course also provides brief overview of deposition and diagenesis of sediments and their influence in the formation of a good source rock. Key properties in evaluation of petroleum reservoir are volume of shale, porosity, water saturation and permeability. Evaluations of these key properties are done by data acquired by well logging. Well logging is the practice of making a detailed record of the geologic formations penetrated. Well logs are physical measurements made by instruments lowered into the hole. Tools recording downhole data can be run either with drilling assembly (LWD) or via wireline. These tools can be electric, nuclear or acoustic based on data acquisition requirements.Mud logs may also be acquired based on visual inspection of samples brought to the surface.The integration of all data across various disciplines helps oil and gas companies in evaluation of formation and reservoir This course is designed for university students or recent graduates of Petroleum Engineering and Geoscience disciplines. It will act as a foundation for their technical and practical knowledge about formation evaluation methods used in oil and gas industry.
