Outline

The project will focus on stratigraphic successions through the North Sea that constitute overburden strata of potential CCS reservoirs. Using North Sea 3D seismic and borehole data, the project aims to characterise features or indicators of potential fluid migration pathways over selected reservoir targets for carbon sequestration. Detailed characterisation of the reservoirs and caprocks, including overlying secondary storage reservoirs will be obtained through mapping of 3D seismic data, further complemented by use of well logs.

This will be followed by mapping of potential fluid migration networks associated with the distinct tectonic styles of the study region. Stress data obtained from the boreholes and published information will be used to create fault reactivation and leakage models for the relevant sequences. In addition, stratigraphic heterogeneities in caprocks that influence the migration of leaking fluids will be taken into account for the establishment of a leakage risk model.

The project benefits from cooperation between the Cardiff University 3D Seismic Lab, one of the top basin analysis research centres in Europe, and the British Geological Survey. You will benefit from state-of-the-art interpretation resources at Cardiff, and have access to BGS’s renowned expertise on CCS. BGS training courses are accessible to the successful candidate.

What is funded

Full UK/EU tuition fees and doctoral stipend matching UK Research Council National Minimum.

Duration

4 years

Eligibility

This project suits a candidate aiming at a career in exploration geology and geophysics focused on sedimentary basins.

You should have a strong interest in seismic interpretation, petrophysics and structural geology. Previous experience using seismic and log interpretation software would be an advantage but not mandatory.
