Oilfield
Relative dielectric permittivity
Oil & gas; Oilfield
The degree to which a medium resists the flow of electric charge divided by the degree to which free space resists such charge. The degree, or dielectric permittivity, is defined as the ratio of the ...
Driller\'s depth
Oil & gas; Oilfield
The depth of a well or features within the wellbore as measured while drilling. The measured length of each joint of drillpipe or tubing is added to provide a total depth or measurement to the point ...
Volumetric cross section
Oil & gas; Oilfield
The cross section of a material to photoelectric absorption, in barns/cm 3 . The volumetric cross section, U, is from the product of the photoelectric factor, PEF or P e , and the electron density. ...
Abandonment costs
Oil & gas; Oilfield
The costs associated with abandoning a well or production facility. Such costs are specified in the authority for expenditure (AFE), and typically cover the plugging of wells; removal of well ...
Polarisation horn
Oil & gas; Oilfield
The effect on a propagation resistivity or induction log of charge buildup at the boundary between two formation layers with different dielectric properties. In a vertical well with horizontal ...
Antisqueeze
Oil & gas; Oilfield
The effect on a laterolog whereby the current lines are no longer properly focused but spread out at a certain distance into the formation. The effect occurs opposite a high-resistivity bed with ...
Cave effect
Oil & gas; Oilfield
The effect of a sharp change in the borehole diameter, such as that caused by a cave or rugose hole, on an induction log. In smooth boreholes of constant diameter, the effect of the borehole is well ...
