Analysis of Reaction and Flow in Stochastically Heterogeneous Porous Media

PROJECT DETAILS ONLY - NO DATA. 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 differential equations will be formulated. The feasibility of solving these stochastic differential equations will be evaluated in this proof of concept proposal, and the expected values and variances for the growth rate and wavelength of the disturbances determined as a function of input parameters. The results will have significant impact on areas such as reactive diagenesis in oil reservoirs and acid treatments of well bores. The investigators will interact with Mobil Tec Co., who are partially matching the proof of concept grant.

1:1.5M scale 'Geology Through Climate Change' poster map covering UK mainland, Northern Ireland and Eire. This poster map shows the rocks of Britain and Ireland in a new way, grouped and coloured according to the environment under which they were formed. Photographs illustrate modern-day environments, alongside images of the typical rock types which are formed in them. The ages of the rocks are shown in a timeline, which also shows global temperatures and sea levels changing through time. The changing positions of Britain and Ireland as they drifted northwards through geological time are illustrated too. It was jointly produced by the BGS, the Geological Survey of Northern Ireland and the Geological Survey of Ireland. It has been endorsed by a range of teaching organisations including WJEC (previously the Welsh Joint Education Committee), OCR (Oxford Cambridge and RSA Examinations), The Association of Teaching Organisations of Ireland and the Earth Science Teachers Association. Although primarily intended as a teaching resource, the poster map will be of interest to anyone seeking to understand the imprint geological time has left in the rocks of our islands. This poster map is free, all you pay is the postage and packing.

Architecture and controls of sinuous submarine channels: analysis of 3-D seismic data, modern channel systems and experimental investigations - Phase1Exps

Data from experimental phase 1. Sinuous submarine channel systems are important sedimentary components of continental margins and form significant oil reservoirs in the deep offshore. Their internal sedimentary architecture and the processes that govern this are very poorly understood, thus limiting their sedimentary predictability. The investigators propose an integrated study to analyse the gross-scale hydrodynamic and sedimentary processes of sinous submarine channels in order to evaluate controls on intra-channel facies distribution. This will be achieved by controlled laboratory experiments, examination of modern systems, and analysis of high resolution 3D-seismic datasets utilising innovative 3D modelling and visualisation technologies. The investigators will then use these results to build generic facies models of intra-channel architecture, and to develop 3D-modelling tools to enhance reservoir prediction.

High-precision isotopic constraints on the timescale of orogenic metamorphic and magmatic processes

PROJECT DETAILS ONLY - NO DATA. This proposal aims at obtaining high-precision isotopic analyses on igneous and metamorphic phases at a length scale and precision necessary to resolve the timescales on which metamorphic and magmatic processes occur. The research requires the high-precision analysis of small amounts of Sr. and Nd by mass spectrometry. Given modern mass spectrometric techniques, the principal remaining controlling factor on the data obtained is the Faraday data collection system. Funding is sought herein to install a new and improved collection system on an existing mass spectrometer in the Department of Earth Sciences at the Open University.

The use of computational chemistry to investigate the behaviour of PAHS in sediments

PROJECT DETAILS ONLY - NO DATA. PAH`s are recalcitrant, carcinogenic pollutants whose complex adsorption behaviour hampers both accurate quantification and strategies for bioremediation. Linking to a pre-existing URGENT funded initiative to assess and model of soil contaminant behaviour (GST/02/1991) this feasibility study will apply computational chemical approaches to model the adsorption/desorption of PAH on humic acid-covered mineral surfaces. The structural information on humic substances, as obtained from the GST/02/1991 study, will allow us to develop realistic computational models for PAH adsorption on humic/mineral systems. Information obtained from the simulations on these systems will be fed back in the GST/02/1991 study and may thus directly influence the development of bioremediation strategies.

Location of Gypsum Dissolution Cavities by Seismic Reflection Surveying

PROJECT DETAILS ONLY - NO DATA. In the north of England, the dissolution of gypsum by groundwater is responsible for many subsidence features where gypsum beds lie within 100m of the ground surface. The subsidence hazard not only threatens housing and other infrastructure, but also requires expensive special precautions for new construction and potentially may sterilize land that would otherwise be suitable for development. Site investigation by borehole drilling is inadequate for identifying cavities in the gypsum beds because a borehole that proves solid gypsum may have missed a cavity by less than one metre. A surface surveying technique that gives areal coverage is required to detect cavities, which may subsequently be proved by targeted drilling. Seismic reflection is the only viable geophysical technique for detecting gypsum dissolution cavities in the depth range of interest (30-120m). In this project, the seismic reflection method will be applied to the detection of gypsum dissolution cavities by acquiring data for a range of near-surface conditions in the areas around Darlington and Ripon. Different acquisition parameters and processing techniques will be compared and evaluated to determine an appropriate strategy for future applications of the seismic reflection method in site investigation. The method is potentially applicable for detection of cavities elsewhere, e.g. salt dissolution cavities (Cheshire), and abandoned mineworkings in coalfield areas at comparable depths.

AR-AR and U-PB Recalibration of Palaeocene-Ecocene Magnetostratigraphy

PROJECT DETAILS ONLY - NO DATA. High-presicion Ar- Ar and U-Pb dating of magmatic events in the British Tertiary igneous province is difficult to reconcile with the magnetostratigraphy. The normally maganetised rocks of Mull Centres 2 and 3 are too old for C26N, much too young for C25N, and of too long a duration to fit into normal cryptpchrons in C26R. The most likely reason for this discrepancy is that the accepted time range of C26N (58-57.6 Ma) is too young by at least 0.5m.y. We propose to resolve the problem by re-determining the age of the Palaeocene-Ecocene boundary by Ar-Ar dating of sanidine from ash layers in northern Jutland. Our Ar-Ar dates will be checked against U-Pb ages of zircon and sphen from the Danish ashes and from the Hebrides.

Soil Chemistry England and Wales (version 3)

This dataset has now been superseded, please see the Estimated Ambient Background Soil Chemistry England and Wales dataset. This dataset indicates the estimated topsoil Arsenic(As), Cadmium (Cd), Cr (Chromium), Nickel (Ni) and Lead (Pb) concentrations (mg kg-1) derived by spatial interpolation of the point source urban soil PHE (potentially harmful elements) data. Urban soil geochemical data generally have large positive skewness coefficients so were transformed by taking natural logarithms. To overcome the bias associated with traditional measures of location (mean) and scale (standard deviation) for log-normal data, the inverse distance weighted (IDW) mean and standard deviation of log transformed element concentrations were used for mapping the spatial variation in As, Cd, Cr, Ni and Pb concentrations. The soil chemistry data is based on GBASE (Geochemical Baseline Survey of the Environment) soil geochemical data where these are available. Elsewhere the stream sediment data are converted to surface soil equivalent potentially harmful element(PHE) concentrations. This dataset covers England and Wales but data is available for the whole of Great Britain, with the exception of the London area where an inadequate number of geochemical samples are available at the moment.

New micro-geochemical traces of fluid and solute transport in sedimentary basins

PROJECT DETAILS ONLY - NO DATA. Sandstones in hydrocarbon basins are usually cemented by quartz: this frequently infills porosity by 50%, and so dramatically reduces reservoir quality. Predictive models for spatial patterns of cementation require to know the sources of silica, and the hydrogeology of cement-forming fluids. The ion microprobe has recently proved capable of in-situ micro analysis (0.02mm), to decipher the record of palaeo-fluids. To date 18O/16O has provided an effective tracer of fluid source, but sources of silica remain obscure. We will use the ion microprobe to investigate new geochemical tracers - B, Li, Al, 11B/10B (sigma11B), 30Si/28Si (sigma30Si) - to simultaneously discriminate silica sources, fluid sources, and fluid migration. This is a key step to more comprehensive predictive cementation models. Tracers will be tested in known hydrogeological settings, and by laboratory experiments.

Determination of Hydraulic Properties of distributed Fractures Using Seismic Techniques

PROJECT DETAILS ONLY - NO DATA. We propose to develop innovative seismic techniques for establishing links between hydraulic or fluid flow properties (porosity, permeability, connectivity) and seismic properties (impedance, velocity, attenuation), and for improving the remote determination of the hydraulic properties from surface seismic and borehole data. A significant part of this project will involve the development of theoretical models of seismic wave propagation in rocks with realistic distributions of fractures and faults, with fluid-rock interaction included in the seismic wave propagation theory. The project will combine analytical studies and numerical modelling tools for simulating wave propagation in fractured porous rock. The research will be guided by, and benefit from, application to field data supplied by the industrial collaborators. The proposed research will improve both seismic wavefield theory and modelling of fluid flow in fractured rock and will have direct application in recovering the critical fluid-flow parameters. The work will fill the gap existing in characterising fluid-rock interaction using seismic methods, and it is expected to provide a strong theoretical basis for time-lapse seismic monitoring of spatial and temporal changes in underground reservoirs. The output will be of direct relevance to the detection of oil/gas migration in reservoirs and groundwater flow in aquifers using field seismic measurements.

Scaling Properties of Fluid Flow in Fractured Rocks

PROJECT DETAILS ONLY - NO DATA. 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 by measurements of elastic, transport and mechanical properties on rock samples with known and controlled crack densities (crack porosities) that span the percolation threshold under a wide range of stress conditions. The measured data will be used to calibrate and validate generic models for fluid and fracture percolation that can then be upscaled to predict permeability at the reservoir scale from wireline logs.

Controls on Matrix and Fracture Flow from Geochemical Analysis of Produced Oil

PROJECT DETAILS ONLY - NO DATA. Predicting oil production from chalk reservoirs relies on quantifying contributions from fracture and matrix porosity, which change during compaction. Cl isotopes in water characterise fluid transport processes. Chalk matrix microporosity and fractures will give different values. We will combine two novel methods, trace water extraction from dry oil and Cl isotopes to characterise porosity from produced fluid. High pressure lab. experiments carrying fracture/matrix porosity in cores will give characteristic brine geochemistry related to poroperm to calibrate field values. We will compare fluid derived porosity regime with values measures on field core. Porosity changes from geochemistry will be compared with compaction in the field.

Localized Flow in Fractured Rock Masses: Mechanisms, Modelling and Characterization

PROJECT DETAILS ONLY - NO DATA. 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 stress. Flow localization is predicted at some critical stress; parameters affecting this localization will be investigated. Flow in the vicinity of boreholes and by grain infiltration will be simulated. The models will be tested against field observations and hydraulic tests in boreholes.

Modelling Porosity Development and Flow in Heterogeneous Media

PROJECT DETAILS ONLY - NO DATA. 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 modelling engine and methodologies to generate porosity templates for use in flow and transport models of fractured aquifers. Although the primary motivation for this study is to enhance our ability to predict flow and contaminant transport in vulnerable fractured aquifers, such as the chalk, the approach is generic and we foresee a wide range of scenarios where the model may be applied. The work has three specific objectives: 1) to produce a generic model of porosity development, 2) to investigate percolation, scaling and self-organisation phenomena in porosity development due to flow, and 3) to model pore structure and flow histories for a range of natural and anthropogenic problems.

Scaling of Fluid Behaviour Associated with Flow Through Complex Geological Structures

PROJECT DETAILS ONLY - NO DATA. 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 flow simulator which can model the impact of geological heterogeneities (clustered fault / fracture arrays) under different stress conditions on fluid flow. The project is collaboration between a structural geology research group (the rock deformation research group), an applied mathematics group (the centre for computational fluid dynamics) and a series of industrial partners (Arco, BP, Shell and Midland Valley).

Quantifying the Effects of Biofilm Growth on Hydraulic Properties and on Sorption Equilibria: M2M Measurements

PROJECT DETAILS ONLY - NO DATA. 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 (102m). In addition, the effects of biofilms on the formation of fine oxide precipitates (FeO, OH, MnO.OH. etc.) and on the sorption behaviour of fluid transported trace impurities (U, Tc, Sr) will also be studied over these scales. These fundamental data will be obtained using a unique combination of experimental methods which will allow the results to be scaled up to field dimensions of distance and time, such that the results may be used by our industrial partners as input to field scale models of the migration of fluids and contaminants.

Multi-Scale Fluid-Flow Path Analysis: Calibration and Modelling Using Mineralisation Systems

PROJECT DETAILS ONLY - NO DATA. 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 development of world-class Zn-Pb orebodies. These data will be used to characterise "building blocks" of differing scales which will constrain numerical modelling of flow associated with individual faults as well as the regional system. We have assembled a multi-disciplinary, international team from Leeds, Imperial College, SURRC, Edinburgh, CSIRO (Australia) and Colorado together with assistance from Tara mines in Ireland to tackle this project.

Fully Determined Fluid Velocity Fields for Complex 2D Media with Multi-Scaled Heterogeneity

PROJECT DETAILS ONLY - NO DATA. 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 heterogeneities. The resulting velocity fields will be published widely and will provide an invaluable resource for the validation of models of fluid flow in complex geometries for which validation ID presently impossible. Three specific studies will also be undertaken; a) a detailed investigation of the non-linear interaction between matrix and fracture flow, b) a study of the scaling laws in the region of the percolation threshold in the presence of fractal fracture populations and significant matrix permeability and c) an examination of the scaling of the velocity flow field and how this reflects material scaling with a view to identifying potential rules for upscaling of fluid simulations.
