A chip and core cannot be independently relied upon as a completely accurate record of interval depths or thickness. The geophysical log is used to confirm the actual depth and thickness of significant lithology intervals.
Down-hole survey or geophysical borehole logging may be used to measure a number of physical properties of the geological formation intersected by boreholes.
MINTEC has 2 sets of Side Wall Density Gamma, Vertical probe sets “Robertson Geologging” and 2 sets of Radiation source (Cs 137). The old version of logging set was acquired on August 2009 and our new version was acquired in August, 2015. MINTEC was experienced over 200.000m in logging. Geophysical logging is carried out by our Radiation workers which are licensed by BAPETEN (National Government of Nuclear Institution) and assist by our reliable logging assistant.
