Solutions for Groundwater

Borehole geophysical logging methods are used to measure physical properties of geologic material around the borehole, borehole fluid properties, and the integrity of well construction materials. Downhole tools manufactured by Mount Sopris directly measure or allow us to draw inference about these sub-surface properties and other aspects important in the ground water community.

Many different downhole measurements are commonly obtained in the groundwater industry, some requiring specific borehole conditions. Natural gamma, for example, can yield information in any borehole condition, including metal or PVC cased holes, fluid-filled holes, and air. Other measurements, like the commonly used resistivity and SP, require a fluid-filled open borehole.

The radius of investigation for most borehole geophysical measurements is typically only a few inches to a few feet around the borehole. Due to the small scale of the measurement, borehole methods tend to produce excellent vertical resolution. The combination of high resolution and greater accuracy make most borehole methods suitable for quantitative measurements and small-scale correlation of stratigraphic properties.
