Estimating the amount of conductive and nonconductive constituents in the pore space of sediments by using electrical resistivity logs generally loses accuracy where clays are present in the reservoir. Many different methods and clay models have been proposed ...

In this study swelling problem caused by claystone containing smectite group clay mineral in Tire Lignite Enterprise (Izmir, Turkey) was investigated and triaxial swelling behavior of the claystone was determined.

This report uses the measured S-wave velocities for recovered core samples by Lee and others (2008) at the KC151 site, reconstituted sands by Zimmer (2003), and well-log data at the Walker Ridge and Alaminos Canyon sites acquired during JIP Leg II (Boswell ...

Consolidated-undrained triaxial testing procedures were used to determine the fully softened shear strength of Eagle Ford Shale, which is a highly plastic clay found in central Texas. The measured secant friction angles of Eagle Ford Shale were also compared ...

As was the case on this project, the uncertainty of foundation performance in shale can lead to overly conservative designs, particularly with drilled shaft foundations. An extensive Statnamic axial testing program was performed to verify that the load-settlement ...

Many classification and testing methods for shale, slaking rock, weak rock, and weathered rock have been developed. However, few of these methods are suitable for field use or are applicable to a wide range of material types. The purpose of this paper is to ...
