Several wells have been used in this paper to demonstrate the utility of this application and how this analysis is used to design cost-effective logging programs. Even though...

.... Such practices consist of seeking the complex relationship between the fracture index and some geological and geomechanical drivers (Facies, porosity, permeability, bed thickness, proximity to faults, slopes and curvatures of the structure) in order to obtain a fracture intensity map using Fuzzy Logic and Neural...

... generated using geostatistical methodology based on well logs, core, seismic data and geological interpretation. Fracture network was described in the reservoir as lineaments (fracture swarms) showing two major fracture trends. The network and its properties, i.e., fracture porosity and permeability, were...

... distribution and a fBm for fracture aperture spatial distribution. The results show that in-situ bacteria growth reduces the permeability hyperbolically, but the porosity of backbone fracture does not change significantly. It shows that the reduction of the permeability proceeds faster for smaller values...

... and formation properties (lithofacies, porosity, permeability, pore fluids, etc) at the well location. The quantified knowledge between formation parameters and seismic response at the well location is exported to the rest of the seismic data (2D sections and/or 3D seismic volumes). This workflow...

... Tscf to 4 Tscf of gas. Key uncertainties for the Jintan field are gross rock volume (GRV) and porosity, permeability (tight streaks, karst and fault features), the initial pressure (due to possible depletion from the nearby producing fields) and the effective aquifer strength. The applied workflow...

.... It was also observed that pore volume compressibility decreases with increasing porosity until the effective porosity reaches a critical minimum value. At porosity higher than the critical value, the pore volume compressibility increases with increasing porosity. This may suggest that reservoirs...

..., they are limited in the applicable model size and are also computationally expensive. This paper presents a practical and efficient method for uplayering of multimillion-cell geologic models. The proposed method defines a displacing front conductivity, a combination of porosity, permeability, and facies (in terms...

... (Lloydminister, Canada), are used to validate the model for the cumulative sand and oil production. Our studies indicate that the enhanced production is mainly contributed (1) by the reservoir porosity and permeability improvement after a large amount of sand is produced, and (2) by higher mobility of the fluid...

... Abstract The triple porosity reservoir investigated is unique with its highly heterogeneous carbonate characteristics. The largest hydrocarbon bearing formations are not only naturally fractured, but also highly vuggy. Special relative permeability, capillary pressure, and compressibility...

This model has proven very robust, and has now been further enhanced by applying more quantitative formation evaluation techniques to determine fracture aperture and porosity.
