Abstract Stress and pore pressure changes due to depletion of or injection into a reservoir are key elements in stability analysis overburden shales. However, the undrained response shales is often neglected but needs be considered because their low permeability. Due anisotropic nature shales, orientation both rock stresses should considered. To account for misalignment medium stress tensor, we used poroelasticity theory derive an angle-dependent expression transversely isotropic media under...
Time-lapse (4D) seismic data analysis is widely used to monitor producing hydrocarbon or CO 2 storage reservoirs and their surroundings. The influence of potentially significant undrained pore-pressure changes around depleting (or injected) appears be neglected in most previous studies. 4D response the overburden depends on stress strains induced by reservoir. These alterations may challenge stable infill drilling well integrity. We have anisotropic static elastic moduli from laboratory...
Abstract The Radio & Plasma Wave Investigation (RPWI) onboard the ESA JUpiter ICy moons Explorer (JUICE) is described in detail. RPWI provides an elaborate set of state-of-the-art electromagnetic fields and cold plasma instrumentation, including active sounding with mutual impedance Langmuir probe sweep techniques, where several different types sensors will sample thermal properties, electron ion densities, temperature, drift speed, near DC electric fields, magnetic signals from various...
Abstract The formations above a producing reservoir can exhibit large mechanical changes, creating risk of significant subsidence and loss rock integrity. These changes be monitored by time‐lapse seismic acquisition, which measures the corresponding velocity via time‐shifts. Third‐order elastic theory used to connect subsurface strains stress these attribute changes. Existing models assume isotropic strain dependence dynamic stiffness in shales. It is important re‐evaluate this assumption...
This study was conducted on a storage reservoir situated in valley, the lower course of Sz¹bruk stream north-eastern Poland, Olsztyn Lakeland mesoregion. The catchment area consists an agricultural and afforested part. A is found part valley. built 25 years ago. It enclosed by dike equipped with outlet box. Outflows from pass through terminal segment to Lake Wulpinskie. results experiment indicate that calcium content water evacuated determined type intensity use, ranging 22.3 mg Ca⋅dm -3...
ABSTRACT: Stresses and pore pressures change around depleting hydrocarbon reservoirs or fluid injection sites as result of reservoir pressure change. Such changes influence the stability new wells drilled may lead to fault activation, resulting in induced seismicity possibly casing damage existing wells. Forecasting requires reliable geomechanical modeling its surroundings. Classical analytical solutions are too simple, so numerical models required. The rocks surrounding often anisotropic...
SUMMARY Changes in pore pressure within geological reservoirs, due to, for example hydrocarbon production, CO2 and energy storage or wastewater disposal, may cause substantial stress changes the overburden, altering propagation velocities of elastic waves. The corresponding time-shifts are detected quantified using time-lapse (4-D) seismic analysis. To invert strains, sensitivity rocks is studied laboratory experiments on core plugs. Such measurements typically conducted at ultrasonic...
ABSTRACT: The connection between undrained pore pressure response to stress in shales and fault reactivation, drilling problems microseismicity observed at significant distances from hydrocarbon reservoirs injection zones has not been thoroughly studied is usually disregarded geomechanical modelling workflows. In our study, we examine what extent the inclusion of affects amplitude total changes expected cause shear failure several overburden outcrop shales. We combine poroelastic...
Abstract The examination of total amounts heavy metals (Hg, Cd, Cu, Pb, Cr, Ni, Zn) was conducted in the outflow from a sewage treatment plant and waters sediments ponds supplied with them. As water passed through pond system, decrease metal concentrations post-treatment supplying observed. highest were found lower observed 1 (except for Zn), which direct receiver sewage, while lowest values noted final pond. concentration decreased consecutive ponds. determined sediment that received...
Abstract Development of wellbore sealant alternatives to cements is a topic high relevance for production and injection wells, permanent plugging abandonment, remediation leakage behind the casing. Some examples alternative sealants are epoxy-based sealants, geopolymers, bismuth-based alloys. Depending on application, sealing materials expected encounter challenging downhole conditions, such as corrosive environments (e.g., CO2, H2S) pressure or thermal cycling. This especially significant...
Laboratory tests were performed on the Draupne shale formation, which may serve as a seal over CO2 storage sites. Different techniques used to assess integrity and mechanical properties of shale, with main objective investigating whether exposure would in any manner alter these properties. The laboratory methods encompass traditional triaxial tests; however, fluid substitution prior increasing axial stress failure. These conducted smaller cylindrical plugs than standard, taking advantage...
