I joined the University of Leeds in 2015 to start my NERC industrial CASE PhD with Badley Geoscience Ltd. My project is part of the Carbonate Fault Rock Group, a joint industry project working towards a fault seal analysis workflow in carbonate rocks. Whilst working on my PhD, I spent a month on placement at Badley Geoscience, during which I implemented my research in to a fault seal model.
Faults have been shown to exert significant control on fluid flow within the subsurface. Considerable amounts of research has been directed towards determining the conditions in which faults act as conduits, barriers or partial barriers to flow in siliciclastic reservoirs. This understanding can help to reduce uncertainty when estimating the hydraulic properties of fault zones in the subsurface. However, limited research has been undertaken on the impact of faults on fluid flow in carbonate reservoirs despite their importance in global hydrocarbon reserves; around 60% of global oil reserves and 40% of global gas reserves are stored in carbonates. To assess cross fault flow potential, and consequent reservoir compartmentalisation, the distribution and petrophysical properties of fault rock within a fault zone must be determined. Fault zone architectural models consist of a localised fault core composed of high strain products exhibiting low permeability (i.e. fault rock). Accordingly, this research works towards a predictive method to estimate fault rock production in carbonate rocks based upon key lithological and fault parameters, whilst characterizing the flow properties of these fault rocks.
