resistivity
Oil & gas; Oilfield
The ability of a material to resist electrical conduction. It is the inverse of conductivity and is measured in ohm-m. The resistivity is a property of the material, whereas the ...
conductivity
Oil & gas; Oilfield
The ability of a material to conduct electricity. It is the inverse of resistivity and is measured in siemens per meter (S/m) or mho/m. The conductivity is a property of the ...
attenuation resistivity
Oil & gas; Oilfield
The ability of a formation to resist electrical conduction, as derived from the reduction in amplitude of the electromagnetic wave generated in a propagation resistivity ...
fracture permeability
Oil & gas; Oilfield
That portion of a dual-porosity reservoir鈥檚 permeability that is associated with the secondary porosity created by open, natural fractures. In many of these reservoirs, fracture ...
microporosity
Oil & gas; Oilfield
That part of the pore space that has a characteristic dimension less than 1 micron. In general, this includes not only very small pores but also the porosity associated with ...
well cleanup
Oil & gas; Oilfield
That period when drilling debris and fluids are still coming out of the formation and perforations. During this time, the skin effect is changing and any well-test results may ...
excavation effect
Oil & gas; Oilfield
That part of the effect of gas on the neutron porosity measurement that is not explained by differences in hydrogen index. By using the concept of hydrogen index, the only ...
