Analytical Services, Inc. (ASI) specializes in the siting and completion of High-Yield Wells. Our staff of hydrogeologists and Certified Professional Geologists utilizes a hands on approach to better understand the hydrogeologic conditions at each project location. Our methodology to locate high yield well targets involves a phased approach including; fracture trace analysis, review of available geologic mapping, review of any local well log reports, performing field reconnaissance, and completing geophysical surveys. The methodology utilizes the above “tools” to identify apparent transmissive zones within the underlying bedrock aquifer that would be expected to yield above average groundwater bearing potential.

Fracture Trace Analysis
ASI geologists utilize both low elevation and high elevation aerial photography. The photographs are analyzed stereoscopically to identify subtle lineaments indicative of zones of bedrock fracturing. The locations of the lineaments are then transferred precisely onto site mapping. The fracture trace analysis extends beyond the site area and enables an evaluation of trends and apparent extent of fracture trace lineaments in the larger site area. Results from the fracture trace mapping are used to select locations for geophysical surveys.
