Dry holes aren't bad luck. They're predictable, and preventable. Join geologist and geophysicist Dr. Héctor Hinojosa for a live, data-driven session on knowing what's beneath your land before you commit to a well.
Dry holes aren't bad luck. They're predictable, and preventable.
A dry hole costs $50,000–$150,000 and produces nothing. In arid terrain, a well often has to go 300 feet or deeper before you even find out whether you hit water. Groundwater doesn't sit where local knowledge or a neighbor's well log assumes it does; it concentrates in fractures, buried channels, and structural traps that don't announce themselves at the surface.
Drill on geology instead of data, miss a fracture zone, mistake a saline layer for fresh water, or simply stop at the wrong depth: any one of these turns a well into an expensive hole in the ground.
There's a way to know before you drill.
In this live session, Dr. Hinojosa shows you how geophysical surveys locate groundwater before a single meter is drilled — using a real desert case study from West Texas.
The four predictable failure points — drilling on geology instead of data, missing the structure, misidentifying the target, wrong depth — and how geophysics closes each one.
What electrical resistivity, electromagnetics, seismic, and seismoelectric methods reveal that a well log alone can't.
From large-property EM screening to seismoelectric fluid confirmation for high-stakes wells.
The West Texas case: turning two sections of featureless desert into three coordinate-tagged, ranked well sites.
Coordinates, depth targets, confidence rankings, and honest uncertainty reporting a driller can act on immediately.
"If you've ever wondered whether your next well is going to come up dry, this is for you."
Watch how eight electrical resistivity imaging lines across two sections of West Texas desert — surveyed under some of the most difficult ground conditions there are — resolved into three coordinate-tagged, confidence-ranked well sites, with minimum drill depths defined before a single meter was drilled.
No theory-only slides. This is a walkthrough of an actual project, start to finish — including the ground conditions that make desert surveys hard, and how CGS worked around them.
Dr. Hinojosa leads Cordillera Geo-Services (CGS), where he combines geological expertise with advanced geophysical methods to give landowners, water resource professionals, and engineering clients a clearer picture of what's beneath their land. Bicultural and bilingual, he's led subsurface investigations — including groundwater exploration — across the U.S. and Mexico, with a specialty in exactly the kind of integrated interpretation this webinar is about: turning geophysical signal into geological meaning.
"Geophysical data without geological interpretation is just signal. We give you meaning."
Live Thursday, October 22 at 10:00 AM CDT. Free to attend. Replay included either way — and you'll leave with a clear picture of how to avoid a dry hole.
