Providing geophysical services to underground resource industries worldwide since 1984
WE USE PATENTED TECHNOLOGY TO DETERMINE LITHOLOGY AND FLUIDS

WHY THE PETRO-SONDE?
The ability to determine the updip from downdip is often the difference between a gusher, a marginal well or, worst case, a dry hole.
DATA RESULTS
Determine lithology breaks.
Track the updip direction.
Depths and thickness of pay zones.
Avoid crossing faults.
HOW IT WORKS
TESTIMONIALS
I definitely recommend it to anyone who wants to drill a well. It is especially an incredible value if you are looking at a multiple drill site. We have a 98% success rate when we drill a well on a site located with your technology.

I have used the Petro-Sonde / Geophysics International since the early 1980’s with good results. I have found the tool useful particularly in defining the limits of reservoirs in the development of a new discovery. The charts provided by a comprehensive survey of the field area prevented the drilling of several dry holes.

We are not endorsing Geophysics International or the Petro-Sonde. With this letter, we are merely stating that we have applied this technology in our oil and gas exploration programs in attempting to resolve subsurface geological problems.
