Case Studies

Location: S.E. Saskatchewan
Storage Tank: 400BBL
Problems: Paraffin Accumulation
Desire: Clean tank with zero entry

Number of Tank: 1
Historical Problems:
This was a clean oil tank with over 2 feet of heavy tank bottoms due to paraffin fall out. All fluid was emptied out of tank prior to treatment

Observed Results:
The tank was treated with 1m³ of bacteria solution and 3m³ of hot water; tank was agitated for 48 hours. At the end of 48 hours a tank truck was tied on and 13m³ of fluid was pulled out; which was recycled and sold.
Treatment Time: 2 days

Location: Central Alberta
Field: Red Deer
Well Depth: 1600m
Problem: Paraffin
Formation: Belly River

Number of Wells: 3
Historical Problems:
Xylene treatments, hot oiling every 3 months

Observed Results:
Extended equipment life, eliminated chemical and hot oiling costs.

Location: Central Alberta
Field: Redwater
Problem: Paraffin
Formation: Viking

Number of Wells: 70
Historical Problems:
Chemicals were used, hot oiling every 3-4 months.

Paraffin problems have been controlled, eliminated need for chemicals and hot oiling. Increased gas production.

Location: Western Saskatchewan
Field: Smiley
Well Depth: 1400—1600 meters
Problem: Paraffin

Number of Wells: 6
Historical Problems:
Monthly hot oiling to keep units running.

Observed Results:

Location: S.E. Saskatchewan
Field: Steelman
Well Type: Injection
Problem: Carry Over Contamination & Scale

Number of Wells: 2
Historical Problems:
High pressure, low injectivity.

Observed Results:
BioAcid stimulation was done on both injectors. Injection rate per day on first well went from 4m³ to 25 m³, second wells injection rate was increased from 35m³ to 71m³ Injectivity rates were maintained for over a year.
