Other Applications

With resistivity logs acknowledged as the foundation of most water, geotechnical and environmental logging, Delta Epsilon has incorporated 16” and 64” normal resistivity log measurements in a manner that does not require an isolation bridle. The GE-9409 combination gamma and electric logging tool simultaneously runs gamma, single point resistance (SPR) and spontaneous potential (SP) logs on standard lightweight single conductor logging cable.

Despite the use of single conductor cable, Delta Epsilon electric logging tools are able to obtain directly measured SP logs in a well-proven manner. This is accomplished by completely eliminating influences induced by the necessity of sending power down hole and multiplexing. Delta Epsilon uses the cable only as a conductor to surface electrodes for this measurement.

Delta Epsilon offers calibrated gamma probes for the quantitative determination of %eU308. Located at the US Department of Energy compound in Grand Junction, Colorado, Delta Epsilon is uniquely situated to calibrate these probes using the world standard radiometric borehole calibration models at this facility.

The use of total count gamma ray logging probes to determine uranium resources in the ground is a long- established practice. To determine ore grade as %eU308, gamma probes must be properly calibrated to determine their efficiency and to be assigned an appropriate K-factor or other calibration factors. The supplied DELogger software automatically calculates and displays %eU308 in real time from gamma logs.

For geotechnical or exploration applications requiring density measurements, Delta Epsilon has developed two “small-source” or micro-density tools that do not require a radioactive materials license in the US and many other places. In an increasingly prohibitive regulatory environment, they offer an alternative to conventional density tools whose use is often no longer possible.
