UKGEOS and Core Sample Analysis. Geomechanical testing was performed to determine triaxial compressional strength, tensile strength, frictional strength and permeability of...

At sub-continuum scales, pore network geometry strongly influences flow and solute transport. Fractures spaced ~0.1 to ~10m impart continuum scales to fractured aquifers which...

Modelling of flow and transport in fractured rock is severely restricted due to the need to represent fractures over a wide range of scales, which demands unrealistically large...

The project will develop and explore the application of scaling methods to strongly heterogeneous flow fields; investigate the loss and retention of information by scaling over...

Fluid flow through natural fractures depends upon the scaling behaviour of their fractually rough surfaces. We have developed techniques for imaging fluid flow in the natural...

Reservoir quality in hydrocarbon reservoir sandstones can be greatly influenced by mineral cementation or dissolution. This can change porosity by 50% and permeability by 105....

This project will use the techniques of stereolithography and PIV directly to measure the fluid velocity field in complex, 2D, geologically realistic media with multi-scaled...

This project will integrate micro- and meso-scale structural and geochemical data from the Irish midlands in order to understand the fluid flow and fluid mixing responsible for...

The influence of biofilm growth on the hydraulic properties of sediments and rocks will be investigated experimentally over scales from microscopic (10-10m) to macroscopic...

This project is designed to integrate geological structural characterisation of fault zones with numerical modelling of flow behaviour at different scales. We will develop a 3D...

The aim of the proposed project is to study evolution in the spatial characteristic of coupled flow and porosity development in heterogeneous porous media. We will develop a...

Coupled (mechanical-hydraulic) numerical models based on the distinct element method will be used to investigate the behaviour of fluid flow in fractured rock-masses under...

Predicting oil production from chalk reservoirs relies on quantifying contributions from fracture and matrix porosity, which change during compaction. Cl isotopes in water...

This proposal is to test the hypothesis that secondary (crack) porosity can be treated as a scaling problem in both fracture and fluid percolation theory. This will be achieved...

We propose to develop innovative seismic techniques for establishing links between hydraulic or fluid flow properties (porosity, permeability, connectivity) and seismic...

Stability of a reactive front in a heterogeneous porous medium characterised by a statistical description of a permeability and/or reactivity will be studied. Stochastic partial...

The project will determine the distribution and magnitude of Tertiary hot fluid pulses throughout the North Atlantic region in order to advance significantly the modelling of...

The aim is to realise the potential of hydropyrolysis (pyrolysis assisted by high hydrogen gas pressures) as a means to provide reliable molecular fingerprints for severely...

Through manufacturing and geophysically characterising the properties and distribution of a range of synthetic gas hydrate morphologies in a range of sediments in the...

to provide reliable molecular fingerprints for biodegraded crude oils and contaminated sediment cores and to facilitate correlation studies The aim is to demonstrate the...
