Background Information
The 9055 tool is a multi-parameter slim hole mining and hydrology
tool which contains a single detector, neutron system using a 1.0 Curie, Am241Be
source, to record neutron porosity of the formation. Additionally, the tool also
records natural gamma, SP, single-point resistance, and optionally, borehole
deviation.
