| dc.description.abstract | The deformation of materials under constant load over time is called creep. The conductivity of fracture produced by hydraulic fracturing decreased over time as a result of this time dependent phenomenon that requires to be studied thoroughly to predict the production loss. Creep deformation happens under different environmental condition including confining pressure, temperature, anisotropy and so on. In order to accurately predict the creep deformation of formation rocks, the creep test requires to be conducted under similar condition as reservoir. In this thesis the creep behavior of five different shale rocks have been studied: Eagle Ford, Mancos, Barnett, Pierre and Haynesville shale. Most of tests were conducted under ambient temperature and high temperature. To study the influence of anisotropy the creep tests were performed on two samples of Mancos, Barnett, Pierre and Haynesville shale perpendicular and parallel to the bedding. The result indicated the temperature and anisotropy have a significant influence on the creep behavior of shale rocks. Increasing the temperature resulted in higher strain rate. It was observed that the parallel samples experienced lower instantaneous and creep deformation compared to the samples cored parallel to the bedding. | en_US |
