Making an accurate estimate of the CO2 storage capacity before commencement a carbon capture and (CCS) project is crucial to design feasibility investigation. We present herein numerical modelling study on in depleted gas reservoirs. First, we show simple volumetric equation that gives reservoir, which considers same volume CH4 at reservoir pressure temperature conditions produced from reservoi...

Two orthogonal pre-production seismic surveys and a seismic survey acquired after eight years of production from the Bullwinkle field (GC 65, Gulf of Mexico) reveal extraordinary seismic differences that are attributed to productioninduced changes in rock and fluid properties. Separate normalizations of these surveys demonstrate that timelapse results are improved by utilizing seismic surveys t...

Field and laboratory spectral induced polarization (SIP) measurements are integrated to characterize the hydrogeological conditions at the Schillerslage test site in Germany. The phase images are capable of monitoring thin peat layers within the sandy aquifers. However, the field results show limitations of decreasing resolution with depth. In comparison with the field inversion results, the SI...

Calibrated models of aquifer-system compaction developed by Helm (1975, 1976, 1977, 1978) and by Williamson and others (1989) indicate that a narrow range of both aquitard inelastic skeletal specific storage values and aquitard elastic skeletal specific storage values have been used to successfully simulate aquifersystem compaction despite differences in depth, thickness, lithology, and stratig...

The majority of residential, agricultural, and industrial areas are situated on cohesive soil in the Nile Delta, Egypt. Excessive pumping from Delta aquifer to meet increasing demands for water could lead system compaction land subsidence. Land subsidence endangers infrastructure such as buildings, bridges, canals, roads, well deteriorating lands agricultural resources. objective this research ...

The nomenclature for Kansas aquifers needs revision. Many of the names currently in use were derived in an ad hoc manner without the benefit of a consistent set of hydrogeologically based guidelines. Because nomenclature forms the basis of scientific discussion of hydrologic issues, names should be clearly defined and consistently applied in order to prevent erroneous or unintended hydrologic i...

The development of agriculture and industry and the increase of population in countries with arid to semi-arid climates have led to more harvesting of groundwater resources and as a result land subsidence in different parts of the worlds. Decades of groundwater overexploitation in the Kashmar-Bardaskan plain in the north-east of Iran has resulted substantial land subsidence in this plain. The p...

Wells screened across multiple aquifers can provide pathways for the movement of surprisingly large volumes of groundwater to confined aquifers used for public water supply (PWS). Using a simple numerical model, we examine the impact of several pumping scenarios on leakage from an unconfined aquifer to a confined aquifer and conclude that a single inactive multi-aquifer well can contribute near...
