Cementation of Oilfield Sandstones: Micro-Geochemical Tracers, Reveal Macro-Fluid Hydrogeology

PROJECT DETAILS ONLY - NO DATA. 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. Such processes were partly controlled by palaeo-hydrogeology. The micro-isotopic and micro-geochemical composition within cements holds a detailed zonation record of palaeo-hydrogeology, which can now be investigated by new micro-scale analytical technology. We will combine conservative tracers and palaeopressures from fluid inclusions with natural isotopic tracers measured by ion and laser microbeam instruments. Statistically based sampling will enable reliable up-scaling to calibrate blocks in basin-scale computer models. This will integrate microanalysis with basin architecture. Study sites are selected to resolve conflicting interpretations of characteristics cementation processes.

The Scaling Behaviour of Fluid Flow in Rock Fractures

PROJECT DETAILS ONLY - NO DATA. 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 rock fractures themselves, in high fidelity physical models, and by using high-resolution numerical simulations. These advances will be used to examine the scaling behaviour of miscible/non miscible fluid flow in fractures, paying particular attention to (i) channelling, fingering, dispersion and flow stability, (ii) surface wettability, (iii) normal and shear deformation, and (iv) the nature and development of fractural fracture matching, experimental (optical, NMR and PET) imaging will be carries out concurrently with numerical modelling on a suite of tuned synthetic fractures. The results will be applied to multi-fracture systems of interest to the oil industry and UK NIREX Ltd.

Quantifying the Scaling of Physical Transport in Structures Heterogeneous Porous Media

PROJECT DETAILS ONLY - NO DATA. 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 large space and long time scale ranges; and, define the dependence between large space/long time scale migration behaviour and the underlying geological model. High resolution, highly accurate flow and transport simulation data sets for a large number of realisations possessing the high variance and strong textures observed in actual geological systems using alternative geological simulators will be used to test upscaling approaches reported in the physical sciences literature and to identify improving upscaling laws where the existing laws are inadequate.

Novel Flow and Transport Models for Systems Exhibiting Non-Integer Flow Dimensions

PROJECT DETAILS ONLY - NO DATA. 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 computer resources. Recently, closely related problems have been studied by mathematicians who have sought, for example, to define a Laplacian for systems with fractal structure. This project aims to combine the hydrogeological need with those mathematical advances. It will develop and test novel numerical methods for modelling flow and transport fractured rock exhibiting heterogeneity and connectivity at multiple scales. The project has strong potential to establish bridgeheads between a variety of theoretical developments and hydrogeological observations.

Tracer Breakthrough, Hydraulic Properties and Fracture Networks at Sub-Continuum Scales in Aquifers

PROJECT DETAILS ONLY - NO DATA. 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 may exceed the size of many practical problems. Sub-continuum flow models often use statistical simulation of explicit fracture networks, leading to serious problems of system identification an uniqueness. This studentship will address this by determining whether tracer breakthrough curves may be used to characterise fracture topography at different scales, either as the sole evidence or in combination with bulk permeability. The main method will be a systematic exploration of the influence of fracture network topologies and scale on tracer breakthrough, using simulations on 2-D and 3-D models which represent the void space explicitly and create dispersion solely as a product of inhomogeneity in flow rate. Results will be compared with existing tracer data and used to infer the characteristics of the fracture networks involved. The outcome hoped for will be a methodology for using tracer tests to constrain fracture geometry in unknown cases.

Mudstone Microstructure Evolution During Burial and Diagenesis and Effect on Caprock Sealing Capacity

PROJECT DETAILS ONLY - NO DATA. Mudstone microstructure is poorly understood even though it has a profound impact upon permeability. Mudstone permeability is critical in defining the rate at which oil and gas leak through oil and gas field caprocks, and the effectiveness of aquicludes utilised in protecting clean confined groundwater supplies and isolating wastes. During burial, mudstone permeability is controlled initially by the depositional fabric and mineralogy and then by mechanical compaction. A secondary stage of (chemical) compaction and permeability evolution will occur during progressive burial when diagenetic reactions, such as smectite-to-illite and clay-carbonate reactions, occur as a result of the faster reaction rates at higher temperatures and the overstepping of thermodynamic reaction boundaries. This research is intended to address the links between microstructure and mineralogy of mudstones, permeability, pore size distribution and their bulk sealing capacity. These data will be placed in the context of the geological history in terms of depth, temperature, pressure and effective stress histories.

Mineral resource polygons Wales version 1

The British Geological Survey (BGS) was awarded a grant from the Welsh Assembly Government Aggregates Levy Fund in 2009 to provide a comprehensive, relevant and accessible information base to enhance the sustainability of mineral resources for Wales. BGS co-funded this project through its Sustainable Mineral Solutions project. This work was completed in 2010. This dataset comprises the digital GIS files which were produced through this project. The major elements of minerals information presented on the maps are; the geological distribution of all onshore mineral resources in Wales, the location of mineral extraction sites, the recorded occurrences of metallic minerals, the recorded location of former slate quarries and significant areas of slate waste and the recorded location of historic building stone quarries. The BGS Mineral Resource data does not determine mineral reserves and therefore does not denote potential areas of extraction. Only onshore, mainland mineral resources are included in the dataset. This dataset has been produced by the collation and interpretation of mineral resource data principally held by the British Geological Survey. The mineral resource data presented are based on the best available information, but are not comprehensive and their quality is variable. The dataset should only be used to show a broad distribution of those mineral resources which may be of current or potential economic interest. The data should not be used to determine individual planning applications or in taking decisions on the acquisition or use of a particular piece of land, although they may give useful background information which sets a specific proposal in context.

Map based index (GeoIndex) water wells

This layer of the map based index (GeoIndex) is a map based index of the National Well Record Archive. This index shows the location of water wells along with basic information such as well name, depth and date of drilling. The index is based on the collection of over 105,000 paper records of water wells, springs and water boreholes. Geological information, construction details, water quality data and hydrogeological data may also be available for some water wells. The amount of detail held on individual sites varies widely and certain fields will have an 'unknown' value where the paper records have yet to be checked for their content. The zero values for the depth represent those for which the depth has yet to be entered into the database from the paper records.

UK Geomagnetic Observatory K-Indices.

The K-index scale summarises geomagnetic activity at an observatory by assigning a code, an integer in the range 0 to 9 (0 being the least active field and 9 the most active field) to each 3-hour Universal Time (UT) interval. K-Indices are available for Lerwick, Eskdalemuir, Greenwich, Abinger and Hartland Magnetic Observatories. From 1954-90 the values are hand scaled, from 1991 to the present day they are automatically scaled. The data not only aids scientific research into rates of change of the magnetic field and increases the accuracy of the BGS Global Geomagnetic Model, but also provides data to exploration geophysicists engaged in current and future oil exploration.

1:250K Geological Maps of Northern Ireland version 2

The 1:250k Geological Maps of Northern Ireland comprise the Superficial Deposits Map (Drift, 1991) and the Bedrock Map (Solid Geology, 1997). These maps identify landscape areas based on their lithology. The scale of the maps is 1:250 000 and provides a simplified interpretation of the geology that may be used as a guide at a regional level, but should not be relied on for local geology. Superficial deposits are younger geological deposits formed during the most recent geological time; the Quaternary. These deposits rest on older rocks or deposits referred to as bedrock. The superficial deposits theme defines landscape areas with a geological name and their deposit-type or lithological composition. The Superficial map shows the deposits within the extent of the six Counties of Northern Ireland. The Bedrock map comprises the bedrock geology and contains dykes and geological faults. Bedrock geology describes the main mass of solid rocks forming the earth's crust. Bedrock is present everywhere, whether exposed at surface in outcrops or concealed beneath superficial deposits or water bodies. Geological names are based on the lithostratigraphic or lithodemic hierarchy of the rocks. The lithostratigraphic scheme arranges rock bodies into units based on rock-type and geological time of formation. Where rock-types do not fit into the lithostratigraphic scheme, for example intrusive, deformed rocks subjected to heat and pressure resulting in new or changed rock types; then their classification is based on their rock-type or lithological composition. This assesses visible features such as texture, structure, mineralogy. Dykes defines small, narrow areas of a specific type of bedrock geology; that is igneous rocks which have been intruded into the landscape at a later date than the surrounding bedrock. Geological faults occur where a body of bedrock has been fractured and displaced by large scale processes affecting the earth's crust (tectonic forces). The Bedrock map shows the main bedrock geological divisions in Northern Ireland and coverage extends to the west into the Republic of Ireland. The printed map includes a stratigraphic column. Digital datasets have been derived from the maps and comprise three layers. 1. Superficial polygons, 2. Bedrock polygons and 3. Linear features. Attribute tables describe the polygon features. These data are generalised and superseded by the 1:10k Geological Maps of Northern Ireland.

BGS Geology - 625k (DiGMapGB-625) 2008

Data identifying landscape areas (shown as polygons) attributed with geological names. The scale of the data is 1:625 000 providing a simplified interpretation of the geology and may be used as a guide at a regional or national level, but should not be relied on for local geology. Onshore coverage is provided for all of England, Wales, Scotland, the Isle of Man and Northern Ireland. Data are supplied as four themes: bedrock, superficial deposits, dykes and linear features (faults). Bedrock geology describes the main mass of solid rocks forming the earth's crust. Bedrock is present everywhere, whether exposed at surface in outcrops or concealed beneath superficial deposits or water bodies. Geological names are based on the lithostratigraphic or lithodemic hierarchy of the rocks. The lithostratigraphic scheme arranges rock bodies into units based on rock-type and geological time of formation. Where rock-types do not fit into the lithostratigraphic scheme, for example intrusive, deformed rocks subjected to heat and pressure resulting in new or changed rock types; then their classification is based on their rock-type or lithological composition. This assesses visible features such as texture, structure, mineralogy. Superficial deposits are younger geological deposits formed during the most recent geological time; the Quaternary. These deposits rest on older rocks or deposits referred to as bedrock. The superficial deposits theme defines landscape areas (shown as polygons) attributed with a geological name and their deposit-type or lithological composition. The dykes theme defines small, narrow areas (shown as polygons) of a specific type of bedrock geology; that is igneous rocks which have been intruded into the landscape at a later date than the surrounding bedrock. They are presented as an optional, separate theme in order to provide additional clarity of the bedrock theme. The bedrock and dykes themes are designed to be used together. Linear features data (shown as polylines) represents geological faults at the ground or bedrock surface (beneath superficial deposits). Geological faults occur where a body of bedrock has been fractured and displaced by large scale processes affecting the earth's crust (tectonic forces). The faults theme defines geological faults (shown as polylines) at the ground or bedrock surface (beneath superficial deposits). All four data themes are available in vector format (containing the geometry of each feature linked to a database record describing their attributes) as an OGC GeoPackage and are delivered free of charge under the terms of the Open Government Licence.
