Core Logging – Time to Hit the Reset Button!
The diamond driller's task is to acquire good core recoveries from accurately depth-registered drill runs that are oriented, if required, from a borehole that is kept on course to target. The geoscientist measures and describes the rock exposed in core and bore, accounts for the core losses incurred, obtains an accurate survey of the borehole path, geospatially locates the data for correlation with adjacent borehole logs to deliver a geological model that is representative of the ground investigated.
Data is recorded relevant to the needs of the engineers or geoscientists for whom a drilling campaign is commissioned, to either explore for ore, then safely and profitably extract the ground, or to design ground stabilizing measures for mega structure construction. Although we are good at mapping features in outcrop, geologists are generally poor at enumerating the measurement uncertainties with which sub-surface data are located.
Workshop attendees will be provided with insight of the processes involved in diamond drilling with consideration of depth referencing, surveying, data processing, core orientation and logging workflows. We will also review the effects of other random, systemic, and human errors found during QA/QC of the drilling and logging process. Attendees are required to bring Windows-based laptops, which will be used during practical exercises.
Attendees will receive certificates of participation. View all workshops.
About the Presenter
Resource Exploration & Development Pty Ltd
Ph.D., lectured in geology from 1980 at the University of Zimbabwe (UZ). He was director of the Zimbabwe Geological Survey (1990–1993), then returned to UZ and set up an M.Sc. in exploration geology. In 1997 he became a consultant, sold diamond drilling rigs, and conducted drilling and geotechnical assurance reviews, trained core loggers, and developed logging software—work he continues after emigrating to South Africa in 2001.
