NAM-IW-130 (Canada West)
CHALLENGE
The client had converted this well from a producer to an injector after 1 year of production. The well initially injected at over 300 b/d. The injection rate had fallen to below 100 b/d within 2 years.
After falling to 20 b/d a year later, an acid job returned the injection rate to 100 b/d, but that lasted only 3 months. The client was looking for a cost effective solution that would last longer.
SOLUTION
Improve connectivity to the reservoir by removing CaSO4 scale and clearing out blockages using electro-hydraulic stimulation technology.
The BLUESPARK® tool was run on tractor to the bottom of the lateral and then was pulsed at each frac port while moving uphole.
The well was treated in 13 hours of total operating time.
“Green” acid was bull-headed down the wellbore to the interval that had just been treated.
The well was put back on production and monitored.
CONDITIONS
Measured Depth: 3,000 m (10,000 ft)
TVD: 1,500 m (5,000 ft)
Bakken shale
OUTCOME
The well saw an immediate increase in injectivity.
The average 3-month injection rate went from 2.2 b/d to 73.9 b/d (3200% increase).
The average injection rate for the 12-months post-BLUESPARK® was 148.3 b/d (6600% increase).
