In 2012, with investments in new technologies and in the staff, added to the professional experience of more than 20 years in geophysics, we accomplished expertise to serve with quality also the services of Borehole Geophysical Logging, focused on projects in the Mining, Groundwater, Environment and Geotechnique areas.
The Borehole Geophysical Logging is a method capable of generating vertical profiles integrating several geophysical methods in the same point. This technique consists in lowering a probe using a hoist until the bottom of a recently finished well. On the way up, the probe performs measurements on the walls of the well, which can determinate radioactivity, resistivity, magnetic, sonic and others. After concluding this procedure, a geophysical profile is obtained with the integrated results of all the probes used.
We apply methods which allow us to investigate up to 1500 meters deep:
- GAMMA NATURAL
- GAMMA-GAMMA DENSITY
- ELECTRIC RESISTIVITY/SPONTANEOUS POTENTIAL/SINGLE POINT RESISTANCE
- ACOUSTIC VELOCITY (P AND S WAVE)
- FLUID RESISTIVITY & TEMPERATURE
- CALIPER
- TELEVIEWERS
- ACOUSTIC TELEVIEWER
- OPTICAL TELEVIEWER
- FLOW METER
- INDUCTIVE CONDUCTIVITY
- INDUCED POLARIZATION
- DESVIO
- COMPONENT MAGNETOMETER
- GYRO (NORTH SEEKER AND RATE)
- BOREHOLE RADAR
- FLUTe
- PACKER TESTING
- MAGNETIC SUSCEPTIBILITY;
- NEUTRON POROSITY;
- CEMENT BOND LOGS.
