The FMS provides oriented, two-dimensional, high resolution images of the variations in microresistivity around the borehole wall. The general purpose inclinometer tool (GPIT) allows for the orientation of the microresistivity measurements from accelerometry measurements and from the declination and inclination components of the earth's magnetic field vector. Applications of the FMS include the following: correlation of coring and logging depth, orientation of cores and location of the cored sections when recovery is less than 100%, mapping of sedimentary structures, and interpretation of depostitional environments. Sonic velocity data can be used with density measurements to calculate an impedance log and generate synthetic seismograms. These wavelet logs are used in turn to directly tie the seismic record to the log and core data.

This tool string is made up of the following tools:

1. Formation MicroScanner (FMS)
2. General Purpose Inclinometer (GPIT)
3. Dipole Sonic Imager (DSI)
4. Natural Gamma-ray Tool (NGT)
