Oilfield

A formation where the velocity of the compressional wave traveling through the borehole fluid is less than the velocity of the shear wave through the surrounding formation. In such conditions a shear ...

surrounding bed

Oil & gas; Oilfield

A formation layer above or below the layer being measured by a logging tool. The term is used in particular to describe the adjacent layers above or below a horizontal well. In a vertical well, the ...

shoulder bed

Oil & gas; Oilfield

A formation layer above or below the layer being measured by a logging tool. The term is used in particular in resistivity logging to describe the layers above and below a reservoir. Some resistivity ...

charged zone

Oil & gas; Oilfield

A formation interval that has become overpressured by the injection of drilling or treatment fluids.

pseudopressure plot

Oil & gas; Oilfield

A plot of real gas pseudopressure (pseudopotential) m(p) versus time function used to analyze gas-well drawdown and buildup tests. The use of the real gas pseudopressure linearizes the diffusion ...

pressure-squared plot

Oil & gas; Oilfield

A plot of p 2 versus time function used to analyze low-pressure gas-well drawdown and buildup tests. The square term arises from substituting a gas-law equation into the differential equations where ...
