NAM-PW-110 (USA California)
CHALLENGE
Client had a well with blocked perforation tunnels from fines circulated into the perforations during a workover. Oil production was down significantly, and all other attempts to clean out the perforations had been ineffective.
The client was willing to try a new technology to clear the perforations to help improve fluid flow into the borehole.
SOLUTION
Unblock the perforations and improve connectivity to the reservoir by using electro-hydraulic stimulation technology.
Unconsolidated sandstone reservoir was treated with BLUESPARK® to improve production.
No special tools or equipment were required on location to complete the remediation operation, other than third party E-Line.
There were 14 individual perforation clusters treated with BLUESPARK® in 8 hours of stimulation time.
Production rates and fluid levels were both monitored for comparison to pre-treatment values.
CONDITIONS
Depth: 1,200-2,300 ft (360-700 m)
Rock type: diatomite
OUTCOME
Perforations were cleared, allowing for increased fluid flow into the wellbore.
Public data from the BLUESPARK® treated well showed an average production increase from 0.8 b/d to 7.6 b/d (comparing 3 months pre-stimulation to 3 months post-stimulation), an 850% increase.
The average rate for the first 6 months post-stimulation was 5.5 b/d, an increase of almost 600% versus the pre-stimulation rate.
