OASIS Drilling Optimization Saves $1 Million on Brown Creek, Alberta
Well
Location
Alberta Canada, Brown Creek Field
Objective
Efficiently drill horizontal well in area
with high potential for hole instability, coal seams, downhole
vibration and lost circulation.
Solution
-
Select OASIS recommended drill bits based on offsets.
-
Optimize hydraulics to minimize stuck pipe incidents.
-
Maintain mud weight below 1200 kg/m3 to minimize fluid
loss in Rock Creek formation.
-
Drill horizontal section in Waubamum formation with Hughes
Christensen STR382 PDC bit.

Result
-
8 1⁄2-in. section drilled up to 50% higher
penetration rates, lower sliding percentages,
saving 263 drilling hours
and 4 trips compared to offset.
-
No loss of circulation in Rock Creek, saving potential
lost rig time and OBM costs based on direct offset.
-
6-in. section drilled with three PDC bits, instead of 8
roller cone bits, saving 84 drilling hours, and four trips.
-
Total savings: $1,033,000 compared
to offset well.
