NAM-PW-108 (Canada West)
CHALLENGE
The clients’ well had initially been perforated and frac’d in the target zone. The well produced at 87% average water-cut for the first 2 years of production. Oil production was below other wells in the same pool and the well was shut-in.
The client was receptive to trying a new type of stimulation to remediate any near-wellbore damage that could be causing the production decline.
SOLUTION
Improve connectivity to the reservoir by using electro-hydraulic stimulation technology.
Sandstone reservoir was treated with BLUESPARK® after being shut-in for 10 months to re-initiate production.
No special tools or equipment were required on location to complete the remediation operation, other than third party E-Line.
Approximately 5 m (16 ft) of perforated interval were treated with our wireline conveyed tool in one 8-hour day.
Production rates and fluid levels were both monitored for comparison to pretreatment values.
CONDITIONS
Depth: 1,300 m (4,300 ft)
Temperature: 43 °C (110 °F)
OUTCOME
The well immediately produced oil at a higher rate that before being shut-in, with less water production.
The oil production increased from 16.3 b/d to 26.9 b/d, comparing 3-month pre to post BLUESPARK®.
The 1-year post-BLUESPARK®production average was even higher at 31.3 b/d.
The water-cut for the 1st year post-BLUESPARK® was down 6%.
