DR HARELAND's research focuses on working closely with all aspects of the Canadian drilling industry including contractors, service companies and operators.

Dr. Hareland's main research interests are centered on the various aspect of drilling engineering optimization with an emphasis on "engineering". The specific research tasks include processes/factors affecting the actual drilling and trouble time it takes to drill an oil or gas well.

Specific research activities related to the NSERC/CAODC drilling chair program at University of Calgary include:

1) Drill Bit Modeling

applied to how the drill bit responds to penetration of different rock layers. We physically model how different drill bit types and designs respond to different operating parameters, rock properties and bit wear status. Research focuses on the development of methods applying advanced modeling and simulation techniques to generate the optimum drilling parameters and their sectional distribution for different drill bits with the ultimate goal to reduce drilling time.

2) Rock Mechanics

applied to the drilling process. We research/model rock mechanical properties related to drilling efficiency and how to obtain them from field operations. These properties are critical in selecting the optimum drilling equipment and operational parameters when drilling a well. The physical understanding of rock behavior and how to obtain and utilize the critical rock parameters from either electric logs, core testing or drilling data has a great effect on drilling efficiency as well as the wellbore stability planning.

3) Drilling Hydraulics

applied to the understanding of non-Newtonian fluid behavior like actual drilling muds and how this is used in the critical estimation and calculation of down-hole pressures while drilling.

4) Drilling System Parameter Integration

is the research and development of a totally integrated drilling parameter effects system that combines all the primary, secondary and tertiary drilling parameters on drilling efficiency and time. Part of this main research activity is the design and development of a fully instrumented scaled drilling rig with the actual response subsystems modeled and programmed.
