Formula of definite point overburden pressure of reservoir layers

open access: diamondEgyptian Journal of Petroleum, 2014
Overburden pressure, Pob, is pressure imposed on layers during the different hydrocarbonic layers operations by the weight of overburden layers. Practically, the geological layers structure varies in matrix and porous media during well head treatment ...

The Effect of Overburden Pressure on Relative Permeability [PDF]

open access: bronzeJournal of Petroleum Technology, 1953
Laboratory relative permeability data on reservoir rock are obtained onsamples which are not subjected to overburden pressure during the permeabilitymeasurements. These data are then used for calculating the performancecharacteristics of reservoirs in which the rock is under the pressure of theoverburden.

Equations of overburden pressure at laboratory: an overburden pressure measurement method in core samples

open access: yesMeasurement: Energy
This study proposes a laboratory-scale overpressure measurement equation to avoid the core damage caused by traditional trial-and-error methods, filling the gap in existing methods. To estimate the overburden pressure before any damage to the core sample,

The propagation characteristics of seismic waves in ultra-deep overburden by large-scale shaking table test [PDF]

open access: yesScientific Reports
The seismic performance of earth-rock dams on deep overburdens has long been a central focus in dam engineering. Understanding the propagation law of seismic waves within a deep overburden is key to revealing the mechanisms of the dynamic response.

Reduction in Permeability With Overburden Pressure [PDF]

open access: bronzeJournal of Petroleum Technology, 1952
Oil bearing rocks, usually found at depths of 2,000 to 10,000'Ft, areelastically deformed by overburden pressure. Although the change in porositywith pressure in a number of example rocks has been shown to be small, it wasthought that overburden pressure might have a significant effect onpermeability.
