  • Use of electrical resistivity tomography to detect temporal near surface changes providing reliable uncertainty estimates for pollution risk assessment

    This postdoctoral project supervised by Prof. Andrew Curtis and Dr. Mark Chapman, undertaken by PDRA Erica Galetti, initially had the goals of analysing microseismicity distributions from actual fracking data, their correlations with production-related activity, and the extent to which anisotropy could be detectable in order to assess fracture orientations. A data set for this was in the university's possession in Edinburgh at the time of writing the proposal. Unfortunately by the time the PDRA was recruited, the data were not available for this purpose: the industrial owner of the data restricted their use. As a result, it was necessary to re-design the project for this PDRA. Remaining in the same general area of using Geophysics to detect subsurface information related to risk assessment of fracking operations, the following project was thought an appropriate replacement: during such operations the near-subsurface (depths of tens to low-hundreds of metres) is potentially at risk of pollution from escaping drilling fluids, reservoir fluids migrating up fracture networks, and by the escape of pollutants from the drilling and production platform or injection-water pool. To enable the near-subsurface to be monitored and concomitant pollution risks tracked over time, a new subsurface monitoring method is being developed and tested that uses electrical resistivity tomography (ERT) to image the near surface. The key new feature of the method is that it is a fully nonlinear Monte Carlo method which for the first time produces reliable estimates of ERT uncertainty in subsurface properties. Reliable uncertainty estimates are necessary for pollution risk assessment, but to-date they have been unavailable. Hence, this new project direction makes a significant contribution to risk assessment of fracking operations.

  • Report of reactive experimental data

    A series of batch reaction experiments using selected UK and European shale samples exposed to brine at reservoir temperature will be undertaken. This will allow the determination of the composition of produced water which will arise from these formations during Fracking. The study will investigate the factors inherent in the shales, such as mineralogy and organic content, which control the dissolved salts, heavy metals and radioactive element composition of the produced waters

  • Report on Hydro-geo-chemo-mechanical facies analysis relative to gas shale’s of key basins

    Report on Hydro-geo-chemo-mechanical facies analysis relative to gas shale’s of key basins. Data will be assembled on the stress regimes, generic thicknesses of deposits, reservoir characteristics, depositional history, hydrocarbon quality, resource potential and natural faulting. The information will be used to provide a realistic framework for the Features Events and Processes characterization in WP 3, to focus the risk scenario work in WP4, and to provide realistic parametrical variations for the modelling investigation in WP5.

  • Report on enhancement potential of seismic techniques

    The analysis of various datasets coming from different well-known hydrocarbon provinces around the world, from within this project and available in the literature, will first aim at setting up operation recommendations depending on the scenarios developed in WP5, operations goals, and target formations.

  • Parameter and model uncertainty quantification

    Global sensitivity analyses techniques based will be employed to identify the key contribution of uncertain parameters to the overall uncertainty associated with predictions provided by each model tested.

  • "Financial report period #1"

    Official reporting in writing every 18 months to the Commission, including establishing and maintaining financial records, coordination of payments and distribution of partner shares.

  • Literature study on multi-continua approaches and upscaling methods

    Uncertainty quantification requires a systematic categorization of the origin of uncertainty, thereby involving stochastic modelling approaches which include modern geostatistically based methodologies.

  • Report on existing (geophysical) monitoring techniques

    review existing monitoring techniques, and analyse methodological and technological extensions, studying the different conceivable network designs, and helping to optimise them.

  • Legislative and Regulatory Review Update

    Legislation and regulatory practices of those member states with significant shale-gas reserves (United Kingdom, France, Germany, Spain, Poland, Austria, Hungary and Romania ) will be collated and compared with each other, and with legislation from some of the other first-world countries with mature shale-gas industries. The main focus of the collation and review will be on how existing legislation recognizes and seeks to control risks arising from scientific uncertainty embedded in the shale-gas industry’s exploration and exploitation practices.

  • Characterisation of key risk scenarios

    Based on the identification of the key risk combinations in task 3.1, the possible parametrical variations of key input variables within the six focused model scenarios will be characterised. These values will be based on an assessment of the different hydro‐geo‐chemical‐mechanical facies characteristics expected within the seven different shale gas basins already identified within Europe (WP2, D2.3). This ensures that events and processes occurring at different sites can be compared and contrasted against a common frame of reference, providing the basis for the construction of a structured knowledge base and generic risk assessment.

  • "Management report period #1"

    Official management reporting in writing will take place every 18 months to the Commission.

  • Report on modelling clay-CH4 and Kerogen-CH4 interactions

    To improve the kerogen modeling and test the assumption (implicitly made in the presently used empirical models) of massive CH4 sorption on kerogen, it necessary to introduce other types of atomic and molecular entities trapped in the mass representation. First, the composition of standard kerogens found in such environment will be investigated from the literature, and then these structures will be implemented in the GenMol

  • FEP Database

    The first consortium meeting will include a two day workshop where all the focused model scenarios will be studied in detail to evaluate both a Features Events and Processes list, and to assess the level of risk associated with each scenario. This list will be provided as a data base to the consortium members, and key risk combinations used to direct the modelling investigation and assessment of monitoring options with the aim of reducing uncertainty.

  • Provision of baseline seismic data access

    Analysis of passive seismic monitoring of the Bowland basin in the UK will provide more detailed characterization of background seismic behavior

  • Ranked FEP list with key responsibilities for further modelling or scientific investigation

    Rank key risk FEP’s associated with lack of understanding or uncertainty identified in WP3 lead FEP work shop. Direct modelling and investigation effort in WP5 to reduce uncertainty, and WP3 work to increase understanding.

  • Scaling Laws for hydrogeologic parameters

    Statistical scaling, uncertainty quantification through rigorous Bayesian treatment of multiple models across diverse space scales.

  • Review of Capabilities of Existing Industry and Research Codes

    Perform a formal review and comparison on the type of processes that each existing code includes in the representation of each phenomenon, on how these processes are approximated, and on how they are coupled.

  • Report on developments for DFN models and multi-continua models

    The results from the DFN simulations with flow solely in the fractures or in both fractures and matrix (while in the matrix we expect mainly diffusion to be relevant) can be compared with a dual/multiple-porosity approach.

  • Report on spatio-temporal distributions of microseismic compared with other baseline data during fracking

    Spatio-temporal distributions of microseismic events will be compared with other baseline data such as treatment curves and fracture distributions in order to better understand the geomechanical characteristics of the reservoir.

  • Database of physical and chemical properties and thresholds relevant to SG

    Collect needed data and information relevant to the materials used in the shale gas industry with potential impacts on air, water and soil pollution. Assemble information on threshold levels, permitted levels, toxicity levels, potential receptors and their respective sensitivities. Collect data and information on admissible levels of induced seismicity as function of the area and the underground formations. Form a database of the relevant physical and chemical properties and of the threshold levels.

  • "Scientific progress report period #1"

    Collation of annual research / scientific progress updates for the first reporting period from each of the WP's

  • Curation and storage of publically available data sets

    Curation and storage of publically available data sets

  • Presentations for public dissemination

    The goal of this task is to make project results available to the general public. This will be achieved by active participation in discussion forums, the media, scientific dissemination activities periodically organized by partner institutions and the like.

  • Project website inaugurated

    Website designed to engage with the public via a project specific Website with a password protected intra net for use by the consortium to encourage integrations between partners and dissemination of findings.
