Micro-g LaCoste/Scintrex Borehole Gravity Survey Services


Micro-g LaCoste and its sister company, Scintrex Ltd., provide logging services with two borehole gravity instruments. The Gravilog™ tool is designed to operate in the slim holes of the mining industry. The Bluecap™ tool is designed for the petroleum industry with higher temperature and pressure ratings.

Borehole gravity tools measure relative gravity within a borehole to the same accuracy levels as surface gravity meters. These measurements are used for remote sensing and deep investigation density logs without the need for radioactive sources.
