The Dual Induction instrument is used to obtain formation conductivity
measurements in high salinity aquifers or in oil-based drilling fluid environments. Using
transmitter receiver coil pairs, it provides deep and medium resistivity measurements used
for fluid saturation calculations. Can be further processed to evaluate water quality and
estimated total dissolved solids.

This tool is designed to respond to the chemistry of rocks as
well as their bulk density. It has the ability to differentiate between sandstone, limestone
and dolomite.

The Compensated Neutron Logging Tool provides one of the
primary porosity measurements used for saturation calculations. Can be used to determine
porosity for a considerable range of borehole conditions and rock types. When combined
with density measurements, it also provides lithology indication, shale volume, and
formation gas identification.

Three elements and their decay chains are responsible for the
radiation emitted by rock: potassium, thorium and uranium. Shale formations often contain
potassium as part of their clay content and tend to absorb uranium and thorium as well. A
common gamma-ray log records the total radiation emitted by the formation.

Three and Five Foot Borehole Compensated Sonic. Allows data to be utilized for
porosity, fracture detection, and formation identification. Interval travel time log provides
seismic correction on depth. With full VDL.

Micro resistivity devices measure the resistivity of the flushed zone and
delineate permeable beds by detecting the presence of mudcake.
