New applications of paleomagnetism and rock magnetism to oil and gas exploration are continually being uncovered, and Robertson is determined to stay ahead of the game. Our state-of-the-art Core Magnetics laboratory facilities have a track record of providing innovative reservoir solutions to IOCs and NOCs across the globe since 1992.
a) Some iron oxides and sulfides can record the direction and intensity of the Earth’s magnetic field and preserve this information over geologic time. Modern magnetometers accurately measure the information stored in these iron minerals which are present in trace amounts in every lithology. The main applications are paleomagnetic core-reorientation to geographic North and magnetostratigraphy as a scientifically established dating technique.
b) Every mineral including typical clastics like quartz yield an interpretable magnetic response when exposed to laboratory induced magnetic fields, for example a grain shape anisotropy can reveal the preferred orientation of mineral grain long axes. We have developed and established sensitive techniques to extract and enhance such data based on mineral magnetic properties.
The main areas of application of Core Magnetics are:
Our Sedimentology expertise extends to both clastic and carbonate facies, and includes the full spectrum of depositional environments.
Nano-metre scale digital imaging, micron resolution digital petrographic analysis and quantitative mineralogy
Our Petrophysical workflows and Rock Physics modeling integrate log, core/cuttings and production data to obtain meaningful physical properties
