There is a huge chasm between the sort of lawful determination that figures in fundamental physics, and the sort of causal determination that figures in the ‘folk physics’ of everyday objects. For example, consider a rock sitting on a desk. In everyday life, we think of the rock as having a fixed stock of dispositions--the disposition to slide on the desk when pushed, to shatter when struck by ...
The determination of fluid flow properties in carbonate rocks is strongly affected by heterogeneity. This paper presents a case study that describes the heterogeneity of a carbonate sample. Then, through multi-scale x-ray CT imaging, core panoscopy, a base flow unit in the sample was selected for property computation. Volumes scanned at different resolutions and fields of view that are spatiall...
Seismic techniques for direct hydrocarbon indication rely on the changes in seismic character which accompany changes in pore fluid content. Interpretation and modeling of direct hydrocarbon indicators (DHIs) require an understanding of the factors affecting seismic velocities and reflection coefficients which are, in turn, dependent on pore fluid properties, rock frame properties, and fluid su...

The concept of brittleness plays a crucial role in the development of tight oil and gas as it reflects a rock’s ability to fail and maintain a fracture in a hydraulic fracture experiment. Conventional methods that attempt to quantify the degree of brittleness associated with a rock mass have a few shortcomings. For example, failure criteria are not used and only the effective moduli are conside...
