Project background

Geological carbon storage is widely recognised to be a key asset in tackling anthropogenic emissions and climate change to reach a sustainable ‘net zero’. Geological heterogeneities can play an important role in the storage units because they control the presence of barrier and baffles. Their impact can either be positive (e.g., decrease the rate at which the CO2 exceeds the limits of the storage site), or negative (e.g., reduce the effective reservoir volume causing CO2 loss). Accordingly, understanding the geological lateral and vertical variability of a CO2 reservoir is a critical aspect when assessing the risk and viability of CCS projects.

Research methodology

The candidate will investigate the sedimentary heterogeneity of the Triassic Ormskirk Sandstone Formation (Sherwood Sandstone Group, offshore UK) representing the full-scale CO2 storage for the HyNet NorthWest project. Data consists of recently acquired seismic reflection data integrated with legacy seismic and borehole data (i.e., wireline logs and core). Methodologies include seismic interpretation of the key reflectors and fault structures as well as petrophysical and sedimentological analysis of wireline logs. This approach allows the characterisation of the large-scale geometries of the reservoir units as well as a medium-scale analysis of the lithofacies and their variabilities. Cores available at the BGS core depository will be described at small-scale (i.e., cm-scale) to produce detailed sedimentological logs. Specific intervals of interest will be sampled to produce thin-sections and Computed Tomography images that will allow a 3-Dimensional analysis of the deposits at the micro-scale.

Training

The successful candidate will join a vibrant research group working on characterising subsurface geological environments needed for clean Energy transition technologies. In addition to the mandatory cohort training events organised by DTP, the candidate will have the possibility to participate in workshops, field trips, schools and conferences organised by professional bodies and the research group. Bespoke training activities will also be discussed and organised in collaboration with external industry partners, with the potential for internships that will be beneficial for the growth of the candidate’s experience.

Person specification

We are looking for a candidate with interest in the characterisation of potential CO2 reservoirs. Prior experience with seismic interpretation, wireline analysis and core description is desirable.

  • Successful candidates who meet UKRI’s eligibility criteria will be awarded a NERC studentship, which covers fees, stipend (£17,668 p.a. for 2022/23) and research funding. International applicants are eligible for fully-funded ARIES studentships including fees. Please note however that ARIES funding does not cover additional costs associated with relocation to, and living in, the UK.
  • ARIES students benefit from bespoke graduate training and ARIES provides £2,500 to every student for access to external training, travel and conferences, on top of all Research Costs associated with the project. Excellent applicants from quantitative disciplines with limited experience in environmental sciences may be considered for an additional 3-month stipend to take advanced-level courses.
