Oil production was below other wells in the same pool, producing 87% water-cut. We boosted oil production by 92% in year one, reduced water cut by 6%.
92% increased production, 1 year after treatment

Challenge
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.
Well Conditions
- Depth: 1300 m (4300 ft)
- Temperature: 43 °C (110 °F)
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.
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®, a 65% increase
- The 1-year post-BLUESPARK® production average was even higher at 31.3 b/d, a 92% increase
- The water-cut for the 1st year post-BLUESPARK® was down 6%
