The Stripa project, which took place in the late 1970s and early 1980s, involved a series of in situ experiments with the objective of investigating the mechanical and hydrogeological behavior of granitic rocks — in the context of their potential t

Multi-Scale Investigations of Liquid Flow in a Fractured Basalt Vadose Zone

Autor: Boris Faybishenko, Jil T. Geller, Robert Podgorney, Christine Doughty, Thomas R. Wood, P.A. Witherspoon

Publikováno v: Flow and Transport through Unsaturated Fractured Rock

This paper introduces an approach to the problem of characterizing flow and transport in a fractured basalt vadose zone. We propose the development of physically based conceptual models on a hierarchy of scales. This approach is derived from field in

Theoretical and field studies of coupled hydromechanical behaviour of fractured rocks—1. Development and verification of a numerical simulator

Autor: Chin-Fu Tsang, P.A. Witherspoon, J. Noorishad

Publikováno v: International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts. 29:401-409

Analyses of hydromechanical behaviour of fractured rocks requires the use of numerical methods, such as the ROCMAS code developed at LBL. We have developed a new version of this simulator which uses mixed Newton-Raphson linearization within an increm

A Laboratory Investigation of Foam Flow in Sandstone at Elevated Pressure

Autor: Clayton J. Radke, Peter Persoff, P.A. Witherspoon, Karsten Pruess, Sally M. Benson

Publikováno v: SPE Reservoir Engineering. 6:365-372

Abstract Use of foam as a mobility-control fluid in underground applications such as enhanced oil recovery and natural gas or air storage in aquifers requires quantitative information on its flow behavior in porous media at relevant conditions. Littl

Aqueous Foams for Control of Gas Migration and Water Coning in Aquifer Gas Storage

Autor: Y.A. Shikari, Peter Persoff, Yu-Shu Wu, Clayton J. Radke, Karsten Pruess, P.A. Witherspoon, Sally M. Benson

Publikováno v: Energy Sources. 12:479-497

Two causes of poor recoverability are migration of stored gas far from the injection well and upward coning of water into withdrawal wells. The authors conducted laboratory and numerical simulation investigation of the use of aqueous foams to block t

Investigations at berkeley on fracture flow in rocks: From the parallel plate model to chaotic systems

Autor: P.A. Witherspoon

Publikováno v: Dynamics of Fluids in Fractured Rock

This is a review of research at Berkeley over the past 35 years on characterization of fractured rocks and their hydrologic behavior when subjected to perturbations of various kinds. The parallel plate concept was useful as a first approach, but rese

Geological problems in radioactive waste isolation - second worldwide review

Autor: P.A. Witherspoon

The first world wide review of the geological problems in radioactive waste isolation was published by Lawrence Berkeley National Laboratory in 1991. This review was a compilation of reports that had been submitted to a workshop held in conjunction w
