In West Macedonia (Greece), CO2 accounts as one of the largest contributors greenhouse gas emissions related to activity regional coal power plants located in Ptolemaida. The necessity mitigate prevent climate change under Paris Agreement’s framework remains an ongoing and demanding challenge. It requires implementing crucial environmentally sustainable technologies provide balanced solutions between short-term needs for dependency on fossil fuels requirements move towards energy transition...
ABSTRACT Geostatistical seismic inversion methods are routinely used in reservoir characterisation studies because of their potential to infer the spatial distribution petro‐elastic properties interest (e.g., density, elastic, and acoustic impedance) along with associated uncertainty. Within geostatistical framework, retrieved inverse elastic models conditioned by a global probability function continuity model as estimated from available well‐log data for entire grid. However, real...
Carbon capture, utilization and storage (CCUS) is considered a major part of the Portuguese strategy for reducing CO 2 emissions. Some industrial sectors, most prominent being cement sector, require implementation to reach carbon neutrality by 2050. This paper presents characterizes areas with potential in mainland Portugal. The lithostratigraphic tectonic frameworks onshore offshore basins are presented; site screening process was conducted, based on basin- regional-scale assessments,...
Iterative geostatistical seismic inversion integrates and well data to infer the spatial distribution of subsurface elastic properties. These methods provide limited assessment uncertainty inverted properties, overlooking alternative sources such as those associated with poor well-log data, upscaling, noise within data. We have expressed uncertain samples, due bad logging reads in terms local probability functions (PDFs). Local PDFs are used conditioning a stochastic sequential simulation...
Geostatistical seismic inversion methods are routinely used in reservoir characterization studies. This is due to their potential inferring the spatial evaluation of petro-elastic properties interest (e.g. density, elastic and acoustic impedances) along with associated uncertainty. In this study, an extension a previously introduced geostatistical method was developed which local multi-distribution functions continuity models under non-stationary conditions were taken into account. The...
Iterative geostatistical seismic inversion methodologies allow the inference of petro-elastic properties subsurface (e.g., density, shear and compressional impedances) that are essential during geo-modelling workflow. The resulting inverted models always approximations to real geology contaminated by errors uncertainties an intrinsic part inverse solution within a setting. main drawbacks this framework is relatively high number iterations needed reach correlation coefficients between...

This approach allows simulation structurally consistent properties using traditional Cartesian...
Numerical methods for the solution of transient radiative transfer problems, in which finite speed light propagation must be accounted for, have received significant attention due to their practical relevance several applications, such as example medical diagnostics and treatments. In these problems it is common deal with strongly scattering media, where diffusion equation (DE) expected perform well. However, predictive accuracy DE becomes poor if anisotropy phase function large, well near...
Conceptually, geostatistical seismic inversion methodologies assume that the original well-log data is used as hard-data, i.e. experimental data, without considering any associated uncertainty, e.g. measurement errors form logging tool. During drilling, it common some zones of borehole wall a given well may collapse due to, for example, significant variation in lithology creating instability along borehole. When these situations occur important noticing measured not be reliable and are with...
Summary Seismic inversion methodologies are key tools in reservoir modeling and characterization for inferring the Earth's subsurface petro-elastic properties of interest. While deterministic seismic allow retrieving a single best-fit inverse model with low computational effort, geostatistical procedures computationally expensive but assessing uncertainty related solution. In this work we propose new approach to accelerate increase convergence rate traditional iterative by integrating an...
