GEO-RDS (Open-Close Flow-meter)

GEO-FBS (Full Borehold Spinner for GEO tools)


Open-close flow-meter module GEO-FBS combined with GEO-6 tools (also to the GEO-4K and GEO-7) and designed to explore the oil-producing, and other types of wells and applied for:

- explore profile of liquid influx within the perforation intervals;

- evaluation of waterproofing properties the construction of wells

- research of downhole filters

- determine the flow rate of the fluid in the borehole

Module GEO-FBS connects with GEO tools using the special single-contact connector, which ensures their mechanical and electrical connection. Work without main module (GEO) is not possible.
