Taking Fossil Fuels to the Next Level - Standards Underpin Extraction, Processing and Distribution
To the average person, the oil and gas industry may appear simple — a matter of literally tapping into a natural resource and distributing it to customers. Of course the matter of extraction is rarely simple, and in the case of emergent ...

Comparison of Gas and Water Pycnometry of Coal Mine Wastes
Coal mine washery wastes comprise two major components whose specific gravities differ markedly. Consequently, their specific gravity is much more variable than that of natural soils and is determined relatively frequently. The specific gravity of ...

Compactor Force and Energy Measurements
Two hand-operated compactors (a vibrating plate compactor and a rammer compactor) were instrumented to measure the dynamic contact force and energy transfer between compactor and soil. The instrumentation schemes, data acquisition techniques, and ...

An Alternative to the Cathead and Rope for the Standard Penetration Test
Previous studies by the authors have found that a cathead and rope when used to perform standard penetration tests (SPT) have resulted in energies reaching the striker plate or anvil substantially less than those resulting from a complete or 100% ...
