Affordable Alternative for Exploration
We use patented technology to determine underground lithology and fluid depths without the need for drilling. This is a huge advantage in oil, gas and water exploration saving 10’s of thousands of dollars on drilling projects. We charge only $2.50 / foot analyzed making our solution one of the most affordable ways to ensure the most production out of your wells.

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.
Depth of lithology breaks.
Track the updip direction.
Depths and thickness of pay zones.
Avoid crossing faults.
Fluid and depth identification.
Presence or absence of hydrocarbons.
"First of all, in a world where there seems to be very little customer service, I would like to thank Geophysics International for their help all the way through this drilling project. They are customer service-oriented, which is very rare in today's world. I heard about them through a friend and decided to try the Petro-Sonde to try to increase my chances on a producing oil well. The Petro-Sonde was easy to use and any questions were just a phone call away. The logs they provided caused me to drill in a different location than I had planned and the logs they provided before drilling were a good representation of the open hole logs after the well was drilled. The well is producing 5 bpd with a small amount of water which is good for the cross cut field. I will be using the Petro-Sonde again on some more points before drilling again."

"We ran three separate Petro-Sonde surveys on the Boatright prospect in hopes of finding a Fry (Strawn) sand anomaly at approximately 2060 - 2070 ft. The analyst with Geophysics International identified another sand, being the Breneke (Canyon) sand, 18 ft. thick, at 1974 ft. and carrying hydrocarbons. We drilled the well, Boatright C #2, and found exactly what the analyst identified and the well was completed as a producer."
- Larry Wellhausen, Owner
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.
