Background Information
The 9060 tool is a multi-parameter slim hole mining and hydrology tool that records natural gamma, SP, single-point resistance. With the tool’s slim-hole design, it can also be used in 5.08 cm (2 in.) steel or plastic cased holes to record natural gamma for lithology. Even with its simple design, this tool records all three parameters simultaneously, without any merging or down logging required.
