... ABSTRACT: Creep deformations in shale gas rocks manifest a few common characteristics: anisotropy, irreversibility, and a strong correlation to the clay and organic content. At the same time, however, the specific creep responses, such as the magnitude of creep and the degree of anisotropy...

... and confining pressure effects in the overall strength of the rock. To complete the characterization of Vaca Muerta s mechanical behavior, some special laboratory studies like Biot s coefficient measurements and creep response characterization were performed on some shale gas core samples; nevertheless...

The model is benchmarked against oedometric compression data for quartz sand. The predicted creep responses at various stress levels agree well with recorded...
