Reservoir Chemistry

This is the study programme for 2019/2020. It is subject to change.


Water injection is the most common method for pressure support and displacement of oil from the reservoir. The chemical composition of ions in the injection water can cause precipitation of scale in the reservoir and in the production well, influence the formation strength/stability, and change the reservoir wettability that influences the oil recovery. Good knowledge about reservoir chemistry can minimize problems related to reduction in injectivity and productivity, and at the same time optimize oil recovery.

Learning outcome

Having completed the course, the student should have gained the following:
Knowledge:
Petroleum reservoirs contain several phases; minerals, formation water and crude oil. The students should know terms and definitions within water chemistry, oil chemistry and chemistry related to minerals and mineral surfaces; topics that are relevant for reservoir chemistry. The student should have gained knowledge related to liquid-liquid and liquid-solid interactions, and an increased understanding of the factors/parameters that influence initial reservoir wettability, and how oil recovery can be increased by wettability alteration by e.g. Smart Water injection.

Skills:
The student should be able to do simple calculations within water chemistry. He/She should, individually or as part of a team, be able to use the modelling tool PHREEQC to investigate water chemistry after phase interactions, and to report.
Having completed the course, the student should be able to communicate his/her knowledge in a good and straightforward way, which will be evaluated at the oral examination.

General competence:
The student should have acquired knowlegde about which factors that are important within reservoir chemistry, especially related to mineral dissolution and precipitation, initial wettability and enhanced oil recovery by water injection.
The student should be able to use the acquired knowledge and the PHREEQC modelling tool to study phase interactions during e.g. waterflooding.
