n: a plot of pressure versus depth that reveals the pressure at which a formation will fracture at a given depth.

n: a way that estimate the value of the deference of well depth layerbreakdown pressure.

n: schlumberger wireline tool thatprovide continuous, orientated borehole vimages. Applications include structural analysis. Fracture identification and analysis, sedimentary analysis, high resolution reservoir analysis,and depth matching/orientation of core

n: mud fluids filter loss is very large, free water seeps into unconsolidated formation resulting in layer swelled.

n: the factor that is used to convert stock tank barrels of oil to reservoir barrels. It is the ratio between the space occupied by a barrel of oil containing solution gas at reservoir conditions and a barrel of dead oil at surface conditions. Also called reservoir volume factor.

the number of barrels of reservoir oil that shrinks to one stock tank (surface) barrel after gas breakout and light end vaporization.

n: a test for the composition of gas or two-phase gascondensate streams. The analysis generally shows not only the composition in percentage of each hydrocarbon present through hexanes or heptanes but also the gallons per thousand cubic feet of liquids by component and the heating value of the gas.

n: the vessel or tower in a gas plant in which fractionation occurs. See fractionate.

n: the pressure gradient (psi/foot) at which a formation accepts whole fluid from the wellbore. Also called frac gradient.

n: a measure of how the strength of the rock (i.e.its resistance to breakdown) varies with depth.

the gradient needed to initiate a fracture.

the width of a fracture at the wellbore. Hydraulic frac width is generated by frac fluid viscosity and/or pump rate (i.e., horsepower).
