Resistivity Imaging Seminar

A three-day seminar focusing on Electrical Resistivity Imaging with the SuperSting Electrical Resistivity Imaging system. The AGI Resistivity Imaging Seminar is designed for those professionals who are involved in, beginning to consider, or have oversight/review responsibilities of others currently conducting DC Resistivity or IP imaging surveys. This seminar is a "hands-on" seminar covering DC Resistivity and IP imaging topics such as: theory; data acquisition; field procedures; data processing; data presentation; and interpretation using the AGI SuperSting Earth Resistivity/IP/SP System and AGI EarthImager software.
