Sequence Stratigraphy: Key to Geopressure Profile Assessment

Selim S. Shaker

…Abstract Lithology and principal stress are the main driving mechanisms behind the development of the subsurface geopressure profile. Lithology distribution creates the conditions that lead to compartmentalization. Sequence/seismic stratigraphy are good guide lines to establish the paleoenvironment and sediment’s spatial distribution in a basin. The overburden (principle stress) is a…

Effects of Stress and Pore Fluid Pressure on Seismic Anisotropy in Cracked Rock

Enru Liu, Simon R. Tod and Xiang-Yang Li

…Summary The cracks in sedimentary rock that is subjected to a change in the applied stress or fluid pressure will undergo a distortion related to their orientation relative to the principal directions of the applied stress. Both the crack distribution and the fluid-flow properties will be altered as a consequence…

Thinking Inside the Box

Murray Christie

…The most powerful tool in any interpreter’s visualization toolkit is memory What makes visualization such a powerful enabler of human memory is its ability to enhance visual patterns from the data in 3D space, enable recognition, organization and classification of meaningful geological patterns and allow the direct inference of depositional…

Inside Reality: Extreme Immersion Elevates Virtual Reality to a New Level

Phil Hodgson

…Visualization and virtual reality technologies conjured up visions of elitist, other-worldly usage when they first gained notoriety for oil industry purposes in the mid-1990s. However, such applications rather quickly morphed from the perceived esoteric realm to the everyday, becoming almost de rigueur now for any number of E&P uses. Still,…

Human Factors in Visual Collaboration

Dave Ridyard

…Introduction Large scale visualization systems have moved from the fringes of our industry to become integral to daily workflows at many oil and gas companies. Visualization is not about visualizing our own data. It is about how we share knowledge with each other. It is a key element in interdisciplinary…
