Potential Petroleum Reservoir Rocks of North-Central Oregon
… has been that volcanic flows have no effective porosity or permeability and poorly sorted volcaniclastic sediments contain a high percentage of mineralogically unstable grains which are too easily and rapidly altered into clays and zeolites for any significant or effective porosity to be …

Simultaneous Multiple Plane to Plane Waterflooding in Fractured Tight Reservoirs
… injectors) with multiple transverse hydraulic fractures nested to create arrays of plane-to-plane injector-producer waterflood displacements between propped hydraulic fractures. The model for each plane-to-plane displacement uses pseudorelative permeability functions to account for conductive …

The relationship of Permian San Andres facies to the distribution of porosity and permeability in the ODC field, Gaines County, Texas.
… injection program, a detailed analysis of porosity and permeability trends in the San Andres reservoirs was made. An assessment of porosity and permeability trends detailing lateral and vertical continuity, lateral and vertical discontinuity, and an investigation of the depositional and …

Failure of asperities by hydraulically induced fatigue: a model for the generation of intraplate seismicity
… connected to fluids within an open fracture. Porosity and permeability within asperities are assumed to be due to microcracks within the rock matrix. Tensile stresses within an asperity are due partly to mechanical loads, but pore pressure is the primary Inechanism by which tension …

Structural diagenesis of bed-parallel and bed-normal fractures, Cretaceous Crato Formation carbonate rocks, NE Brazil
… of the Araripe Basin provide information on the fracture porosity evolution in laminated members of early Cretaceous Brazilian interior basins and provide insight in to the Crato Formation as an analog for offshore reservoirs and its role as a semi-permeable aquitard in the Araripe Basin. …

A Parametric Study and Economic Evaluation of Drilling Patterns in Deep, Thick CBM Reservoirs
… from CBM. These characteristics include fracture permeability, fracture porosity, gas content, and desorption time. The yardstick for comparing the economical practicality of different drilling configurations under diverse reservoir properties is the Net Present Value (NPV).

Hydrogeology and stream interactions of the Edwards Aquifer in the Salado Creek Basin, Bell and Williamson Counties, Central Texas.
… Edwards aquifer within the Salado Creek basin. Fractures associated with faulting as well as weathering, diagenesis and neo-tectonic stresses contribute directly to the porosity and permeability of the aquifer. Groundwater flow is dominated by vertical fractures and bedding pane separations, …

Subsurface stratigraphy and petrology of a cool-water carbonate fracture reservoir - the mid-tertiary Tikorangi Formation, Taranaki Basin, New Zealand
… is New Zealand’s only commercially-producing fractured-carbonate reservoir, but is poorly understood in a stratigraphic-sedimentological-diagenetic context. Based on correlation between laboratory and geophysical well log data a carbonate facies-based lithostratigraphy has been established for …

Hydrogeological characterization of the Mabou Group in the Picadilly region, New Brunswick
… within the Mabou: the Upper Mabou; vuggy porosity directly above gypsum-infilled fractures; vugs and fractures within the Medium Sandstone subdivision; and the lower Mabou Siltstone at the base of the Mabou Group (within ~15m of base). Three of these zones are of interest as they tend to …

Diagenesis of the middle member of the Bakken Formation, Williston Basin, North Dakota

Seismic Expressions of Paleokarst

Model for a Shale Gas Formation with Salt-Sealed Natural Fractures
There are reported cases of hydraulically fractured shale wells that exhibit boundary dominated flow in a very short period. This study suggests that dissolution of salt-sealed natural fractures in the shale offers a novel explanation for the early boundary dominated flow. We first discuss a …

Impact induced porosity of terrestrial impact craters : a gravity study of Meteor Crater.
… Crater, and we used these data to constrain the porosity variations across Meteor Crater that were induced by the crater-forming impact event. We performed a gravity survey at the crater and merged these new data with legacy gravity survey data. From the resulting merged gravity data set, we …
