About this Research Topic
Rock physics is the discipline that allows for characterizing physical properties of rocks based on both destructive and non-destructive methods of investigation, such as wide band frequency experiments of stress-strain on field samples under varying conditions of saturation and pressure, wave propagation, digital technology, and other multiphysics modelling methods. This mainly requires the establishment of constitutive relations with particular attention to the interaction between the mineral components and the saturating fluids. These relations can be of elastic, electromagnetic or diffusive (flow) nature. Furthermore, rock physics promotes the integration of many fields, such as geology, geophysics, petrophysics, mining and resource exploration, hydrology and natural hazards.
The emphasis is clearly growing in favor of the non-destructive methods (seismic and electromagnetic) but there is a lack of real case studies and field applications for demonstration of the robustness of the modeling methods. Geophysical methods are sensitive to the physical properties that mainly involve fluid type, porosity, permeability, mineralogy and the presence of cracks or fractures. Experiments, theories and numerical methodologies are essential for quantitative characterization of subsurface geological structures, processes and the detection of geofluids. This Research Topic accepts contributions regarding novel methodologies and applications to characterize the physical behavior of rocks aiming at geofluid detection. With geofluids being the underlying theme of the call, we welcome submissions in all types of applications from energy (petroleum and geothermal), mining and hydrogeology to natural hazards (volcano and earthquakes). These fields can promote the cross and integration of different subjects, which can be helpful for improving the developments of high-precision exploration methods. We expect to solve the pivotal problems in the basic aspects of fundamental theories and methods and common prospective technologies from different areas.
We encourage the submission of manuscripts covering different topics, from pure and fundamental research to more applied demonstrations and integrated case studies. More specifically, we suggest the following topics:
• Novel rock physics experiments, theoretical approaches and numerical modeling. Laboratory measurement of rock physical properties, wave propagation theories and numerical modeling approach for underground heterogeneous rocks;
• High-precision inversion of strata properties from geophysical data. Stability-enhanced, high resolution, high precision, rock-physics-model-based, and linear or nonlinear inversion schemes by using geophysical data;
• Geofluid detection workflows and applications with case studies. New techniques, methods and workflows for detecting geofluids applied to the actual work area. Analysis by comparing the prediction results and real data;
• Lab to field models and applications. Rock physics models established based on the rock physical properties to support the prediction of the formation rock properties by combining field and experimental data.
We mainly seek contributions covering the above topics but will consider works with more general scopes where pore fluids play an important role.
