Paleomagnetic core orientation service is one of the main paleomagnetic services provided by Applied Paleomagnetics to clients in the petroleum and geotechnical industries around the world since 1986. The first commercial use of our paleomagnetic core orientation service, in 1982, was on the U. S. Department of Energy's Multiwell (MWX) project in Mesaverde Formation tight gas sands in the Piceance Basin, near Rifle, Colorado. The founders of Applied Paleomagnetics first developed paleomagnetic core orientation technology while working on the MWX project. We have subsequently tested and refined our paleomagnetic core orientation service in paleomagnetically orienting over 18,000 feet of cores from around the world.. Paleomagnetic core orientation is important for determining reservoir anisotropy directions from fractures and bedding, including coal cleats in coalbed methane reservoirs; planning optimum trajectories for deviated and horizontal wells; determining in situ stress from induced fractures or geomechanical test samples; predicting orientation of hydraulic fractures; and determining sediment transport directions, sand-body geometry, and structural dip. Advantages of our paleomagnetic core orientation service are that a scribing shoe is not required, entailing no risk to the hole; our paleomagnetic core orientation service requires no downhole equipment and uses no valuable rig time; our paleomagnetic core orientation service is not prone to downhole mechanical failures; all core orientation procedures are conducted away from the rig site; our paleomagnetic core orientation service permits visual inspection of the core prior to orientation; and cores can be paleomagnetically oriented even if they have been in storage for decades. Since 1982, Applied Paleomagnetics has conducted over 100 comparison tests of our paleomagnetic core orientation service against borehole image logs and conventional and electronic multishot. These comparison tests reveal that our paleomagnetic core orientation service generally agrees within 5 degrees with borehole image logs, but commonly differs by very large angles from electronic and conventional multishot, indicating serious core orientation problems with multishot.
