Potash Logging, Canada 



This was supposed to be a winterized drill rig!  That was cold comfort to the slim-hole logging engineer and me, as we spent 18 hr, huddled in his camper shell logging unit running the logs for this borehole. 

After a short nap, I prepared the Multiple Log Potash Assay, presented it to the client and then drove through an ice storm to the airport for my trip home. 

The major difference between slim-hole logging and major vendors wireline logging operations is the crew size (1 man) and the logging sonde sizes (2.5 " x 3 - 20 ').  Slim-hole logging vendors also usually need a little more care and handling than major venders. 

It has been my experience, however, that I can get slim-hole wireline logging vendor products with quality comparable to those of the major logging vendors. 

How May I Help You Raise Your Slim-Hole Logging Vendor's Performance?
