The objectives of this data acquisition project were to complete the downhole geophysical logging of two coreholes G-3801 (253604080183501) and G-3802 (252820080205001), which are the deepest wells at monitor well sites M0009A/B and M0011A/B. The USGS staff provided and ran the following geophysical tools: gamma ray, fluid conductivity and temperature, EM-induction, 3-arm caliper, full wave form sonic, heat-pulse flowmeter, spinner flowmeter, and an OBI-40 Mark III digital optical tool. The logs were processed and displayed using WellCAD software and provided to SFWMD hydrologists to be used in planning monitor well construction.
