Overview

Subsurface applied geoscience forms the basis for the interpretation of stratigraphic, structural, mineralogical and hydrological properties in the subsurface. This is critical to the assessment of economic value, since subsurface rock properties and architecture govern how fluids are stored and produced. This unit describes the fundamentals of the subsurface environment, from basin to pore scale, and introduces the key information needed to understand rock physical properties, mechanical strength, permeability and heterogeneity. The unit covers depositional system analysis, with a focus on resource geology (hydrocarbons, geothermal and carbon capture) subsurface data analysis from drilling operations, and the assessment of subsurface uncertainty.

This course unit detail provides the framework for delivery in 20/21 and may be subject to change due to any additional Covid-19 impact.  Please see Blackboard / course unit related emails for any further updates.

Aims

This unit is designed to introduce students to the analysis of sedimentary basins, their structure, sedimentary fill and fluids for resource assessment.

 

Learning outcomes

On the successful completion of the course, students will be able to:

ILO 1

Understand the different types of sedimentary basin, and be able to describe the relationship between basin type, plate tectonics and heat flow

ILO 2

Demonstrate an understanding of sedimentary rock (siliciclastic, carbonate, evaporite) in core and outcrop and explain the relationship between basin evolution and the type and distribution of sediment.

ILO 3

Identify different types of faults from seismic data and in outcrop and explain the fundamental kinematics behind their formation

ILO 4

Calculate pressure and temperature variations with depth using typical from standard subsurface data sets, and interpret the controls and importance for reservoirs and fluids in the subsurface.

ILO 5

Describe how sediments lithify and how rocks change during burial and uplift as a result of physical and chemical processes resulting from rock/water interaction within different basins and at changing pT conditions.

ILO 6

Recognize the main aqueous and petroleum fluids in the subsurface.

ILO 7

Analyse the key processes and controls involved in organic matter maturation, fluid flow, hydrocarbon migration.

 

ILO 8

Assess the key drivers in subsurface business and the importance of mitigating risk and uncertainty.
