Wireline Logging
What is a Wireline Log
A log is a continuous recording of a
geophysical parameter along a borehole.
Wireline logging is a conventional form of
logging that employs a measurement tool

Permeability
Theory
The permeability of a rock is a measure of the ease with which the rock will permit the passage of

Porosity
Theory
The porosity of a rock is the fraction of the volume of space between the solid particles of the rock to
the total rock volume. The space includes all pores, cracks, vugs, inter- and intra-crys

TEMPERATURE AND WATER RESISTIVITY
For shale-free formations, the conduction of electrical current is almost
entirely carried by ions in the formation water. Quantitative calculations of oil or gas
saturation are therefore predicated on a knowledge of the
POROSITY LOGGING
The porosity of a zone can be estimated either from a single porosity log
(sonic, density, neutron, or magnetic resonance log) or a combination of porosity
logs, in order to correct for variable lithology effects in complex reservoirs. In
