Some Effects of Overburden Pressure on Oil Shale During Underground Retorting [PDF]
Society of Petroleum Engineers Journal, 1966 Abstract Some effects of a simulated overburden pressure on oil shale during retorting are presented. The results are applicable to underground retorting in systems where there is no stress relief. A core press was fabricated, using pyrex microbeads to transmit pressure to the oil shale samples ...

Overburden pore-pressure changes and their influence on 4D seismic [PDF]
SEG Technical Program Expanded Abstracts 2017, 2017 Changes in seismic two-way travel time in the overburden can be attributed to pore pressure changes in the underlying reservoir. Since cap rock permeability is very small, these stress changes occur without drainage on short term, which means that, depending on stress path, pore pressure may also change in the overburden.

Testing of Laterally Loaded Rigid Piles with Applied Overburden Pressure
International Journal of Offshore and Polar Engineering, 2015 Small-scale tests have been conducted to investigate the quasi-static behaviour of laterally loaded, non-slender piles installed in cohesionless soil. For that purpose, a new and innovative test setup has been developed. The tests have been conducted in a pressure tank such that it was possible to apply an overburden pressure to the soil.

Dynamic responses characteristics of bedrock and overburden layer slope with anchored frame piles based on shaking table test [PDF]
Scientific ReportsTo adapt to higher and steeper slope environments, this paper proposes a new type of support structure called an anchored frame pile. The study designed and conducted a series of shaking table tests with three-way loading.
