Overview

Ore genesis, petroleum reservoir engineering, oil and gas migration and contaminant transport in aquifers and surface waters are just some areas of study for which an understanding of water chemistry is required. This module provides exposure to some of the key physico-chemical processes involved in water-rock interactions with the Earth’s crust.

Pre/co-requisites

NONE

Aims

To outline the principles of the major physico-chemical processes involved in water-rock reactions within the Earth’s crust.

 

Learning outcomes

By the end of the course a successful student will understand major physico-chemical processes involved in water-rock reactions in the Earth’s crust, including:

* understand the nature of water in the crust

* understand major controls on the occurrence and flow of water in the Earth’s crust

* understand the principles of aqueous speciation

* understand the principles of mineral-fluid and gas-fluid equilibria

* understand the principles of interactions between aqueous fluids and mineral surfaces

* understand the principles of kinetic controls on water-rock reactions

* understand the principles of controls on isotopic variations in various reservoirs and during water-rock reaction.

* quantitatively determine mineral solubility, chemical speciation and progress of mass transfer (including isotopic and kinetic) processes given suitable thermodynamics, kinetic and analytical data

* with respect to a relevant problem in water chemistry, demonstrate an ability to interpret, integrate and critically evaluate data in the light of defined aims and objectives and the uncertainty that is always inherent in our knowledge of particular systems

Assessment methods

ASSESSMENT This course consists of 10x1 hour lectures each followed by a two hour problem solving practical class where you will work with the help of the lecturing staff. The practical classes allow for formative feedback on your progress with the set problems. Assessement will take the form of reports that build on and synthesise the work you have done in class. Lecturing staff will provide feedback on the reports. The course places:a 27 % weighting on the course reports;a 40 % weighting on the January exam; and a 33 % weighting on an independent project

Feedback methods

Feedback on course reports will generally be during the following weeks’ practicals.
