Keck Gamma Ray System

The Keck Gamma Ray System is used in exploration for uranium, potash and base metals as well as for petroleum and groundwater. The system identifies lithologies and stratigraphic correlations in boreholes, cased or uncased, liquid or air filled. For petroleum and groundwater exploration, the system provides information on the sequence of rocks in the borehole, and it can also be used to locate non-radioactive minerals such as coal.

• Measures the total gamma ray radiation emitted by uranium, thorium or potassium-40 present in the subsurface strata
• Portable and hand-operated
• Measured data points are taken in intervals and then plotted on logging forms for graphic presentation and interpretation
• The probe is 1.5" O.D. x 28" in length, constructed of stainless steel
• Can be used in combination with the Borehole Resistivity System for a more precise determination of subsurface lithology

Keck Borehole Resistivity System

The Keck Borehole Resistivity System is a rugged, portable, hand-operated downhole logger which
measures both apparent resistivity and the natural self-potential (SP).

Applications include mineral exploration, subsurface mapping (isopachs), locating fresh and salt-water bearing information; lithologic and structural correlation between wells, and well construction.

• Measures both resistivity and self-potential (SP)
• Resistivity is read in a range of 0-10,000 ohm-feet
• Self-potential is read in a range of 1-1,000 millivolts, positive or negative
• Battery powered readout instrument, and indicator for resistivity and SP in a rugged water tight case
• 500 feet of four-conductor downhole logging cable mounted on a portable hand reel
• 1" diameter probe assembly
• Two-single conductor insulated surface lines

AquaVISION Colloidal Borescope

AquaVISION provides services and instrumentation that can measure groundwater velocity, direction and particle
size all in real time. They accomplish these difficult tasks by using proprietary hardware and software known as the
“AquaVISION Colloidal Borescope System.”

AquaVISION’s Colloidal Borescope System was developed by a team of research scientists to accurately determine groundwater velocity, direction and particle size in real time. Current down hole technologies only allow for a few groundwater flow measurements per day. The AquaVISION Colloidal Borescope System yields thousands of data points per minute for hours of statistically assured data.

Benefits:

• Assessing groundwater capture zones
• Planning locations for monitoring and
  extraction wells
• Accurately calibrating groundwater models
• Tidal influences
• Industrial hydrology
• Gathering evidence for groundwater contamination litigations
• Can observe flow at the pore scale which measure velocities ranging from 0 to 25 mm/sec
• Evaluate “cross-hole” hydraulic connections
