Pore Pressure

Some articles on pressure, pore, pores, pore pressure, pore pressures:

Well Control - Formation Pressure
... Formation pressure is the pressure of the fluid within the pore spaces of the formation rock ... This pressure can be affected by the weight of the overburden (rock layers) above the formation, which exerts pressure on both the grains and pore fluids ... Grains are solid or rock material, and pores are spaces between grains ...
Impacts of Accretionary Wedges
... as critically tapered wedges of sediment demonstrate that pore pressure controls their taper angle by modifying basal and internal shear strength ... Results from some studies show that pore pressure in accretionary wedges can be viewed as a dynamically maintained response to factors which drive pore pressure (source terms) and those that limit flow (permeab ... In one such study, it was found that as sediment permeability is increased, pore pressure decreases from near-lithostatic to hydrostatic values and ...
Corrected D-exponent
... dc-exponent (dc-exponent) as used in mud logging and formation pore pressure analysis in the oil industry, is an extrapolation of certain drilling ... It is regarded as one of the best tools for pore pressure evaluation ... hence the "c" notation) to the d-exponent method previously used for estimating formation pore pressures ...
Soil Mechanics - Seepage: Steady State Flow of Water - Darcy's Law
... Darcy's law states that the volume of flow of the pore fluid through a porous medium per unit time is proportional to the rate of change of excess fluid pressure with distance ... to the intrinsic permeability, the cross sectional area, and rate of pore pressure change with distance, and inversely proportional to the dynamic viscosity of the fluid ... The negative sign is needed because fluids flow from high pressure to low pressure ...

Famous quotes containing the words pressure and/or pore:

    The mother whose self-image is dependent on her children places on those children the responsibility for her own identity, and her involvement in the details of their lives can put great pressure on the children. A child suffers when everything he or she does is extremely important to a parent; this kind of over-involvement can turn even a small problem into a crisis.
    Grace Baruch (20th century)

    Mistresses are like books; if you pore upon them too much, they doze you and make you unfit for company; but if used discreetly, you are the fitter for conversation by ‘em.
    William Wycherley (1640–1716)
