Swell Potential Versus Overburden Pressure
Geotechnical Testing Journal, 1993Abstract Data were collected and reviewed pertaining to one-dimensional vertical free-swell tests performed on existing fill soils from various projects located in Southern California. The purpose of reviewing the data was to evaluate the effect of overburden pressure on the swelling potential of expansive soils.

Equations of overburden pressure a core sample at laboratory
International Journal of Petroleum Engineering, 2014The control of damages during the set up of the determining overburden pressure apparatuses in the types of related experiments to flooding is one of the main purposes at the enhanced oil recovery and mechanic rock laboratories. Therefore, the uncertainly of accurate overburden pressure is not only time consuming but also is very expensive.

Geotechnical and Geological Engineering, 2020
In order to study the mining pressure on the upper coal seam in the fault, the working pressure of the working face with a hard rock roof is based on the production geological conditions of the 3301 working face of Yiqiao Coal Mine. Use flac numerical simulation software to establish a three-dimensional numerical calculation model of mining face, and ...

Effect of effective overburden pressure on geomembrane/soil interface transmissivity
Geosynthetics International, 2008Fluid flow through a defect in the geomembrane of a composite geomembrane/soil liner (flow rate tests) and interface transmissivity tests between a geomembrane and a soil layer were conducted. The results are compared, and the effect of overburden pressure p′ on the geomembrane/soil interface transmissivity θ and interface thickness tin is ...

Effect of Overburden Pressure on Some Properties Of Sandstones
Society of Petroleum Engineers Journal, 1962Abstract Experimental data demonstrate that physical properties of porous rocks change under pressure. In this paper an assumption is made and proved that under pressure the changes of physical properties such as porosity, density, permeability, resistivity and velocity of elastic waves are controlled to a large ...

International Oil & Gas Conference and Exhibition in China, 2006
Abstract With the prolonged time of development and increased interlayer pressure difference, there is numerous cement channeling problems between isolated zonal intervals in production and injection wells in Daqing Oilfield. The cement channeling problems, especially in long intervals, change the original layers developed and make the ...

ULTRASONIC SHEAR‐WAVE VELOCITIES IN ROCKS SUBJECTED TO SIMULATED OVERBURDEN PRESSURE
GEOPHYSICS, 1962Ultrasonic equipment has been developed to measure shear‐wave velocities in small rock samples at hydrostatic pressures up to 2,400 psi. Under certain optimum conditions dilatational wave velocities can also be determined. The method employs a beam of ultrasonic energy passing through a liquid in which a quarter‐inch‐thick parallel‐sided sample of ...
