Dynamic Video Survey Without Pump Removal
BESST provides dynamic video survey without pump removal for municipal, industrial, agricultural, groundwater remediation and monitoring wells. 3/4″ (OD) video camera survey with pumping condition reveals the condition of wells. Purpose of the miniature camera survey pinpoints where sand invasion comes from screen intervals bleached, finds cavitation of the screens and can be used to profile the entire zones for the maintenance or prior to rehabilitation of the wells.
Several Steps to Profile Your Wells
- Monitoring or water supply wells from with boreholes from 1.0”-25” can be surveyed with the small 3/4” X 10” camera.
- Camera can be lowered through an access tube as small as 2” or straight into a borehole through an access port. (Larger cameras cannot gain access without the costly procedure of removing the pump column.)
- Can be used to find sand producing zones, blocked or damaged screen intervals, and damaged well casing which affect production capabilities.
- Viewing the inside of the well under pumping conditions, can be used to determine not only where a damaged section of casing or screen is, but how it acts at different pumping rates.
