Drillers deal with borehole stability issues in typically unconsolidated heavy oil reservoirs by selecting the right bit for high penetration rates, and the correct drilling fluid to ensure circulation and cool the bit.
Enables continuous drilling without costly delays and provides well placement and trajectory options to optimize heavy oil recovery.
Optimize your overall drilling performance and reduce time to TD through integrated design, execution and evaluation work processes.
Drilling Fluids
At the surface, drillers must make sure they have enough pumping capacity to keep fluids circulating, especially in long, complicated wells. Using the proper drilling mud can also keep the oil from coating the borehole and tubing string, and from reaching the rig floor where it can create safety and environmental issues.

SAGDRIL
An environmentally acceptable water-based drilling fluid that addresses one of the most prevailing challenges of heavy-oil exploration: preventing tar or bitumen from balling the BHA.
Ranging Tools
Ranging tools enable SAGD drilling to be more effective. Depending on the formation sand quality, wells are typically 4 to 6 m apart. To ensure good quality, injector wellbores are placed in the optimum location to ensure long-term thermal production the ability to control the drill bit relative to the location of the producer well is essential.
