Tar
Sand Well in Northen Alberta
This well,
though new, had never been productive. The well was initially perforated
and, although it was anticipated that it would flow or pump at commercial
rates without stimulation, it was unable to do so.
After re-perforation the well had a brief surge of production but died back
down. The operator decided to try a competitoršs propellant stimulation
treatment. The well again had a brief surge in production but then died
completely. At this point it was decided to try Propellant Fracturing &
Stimulation.
Although the initial production increase was relatively small, the well
gained rate for several days, leveling off at a sustained economic rate or
about 35 BOPD. After subsequent pump adjustments, production stabilized at
an average of 48 BOPD.
