Conventional stimulation techniques were not economical or had proven ineffective. We delivered a sustained production increase in this mature oil field.
One year post treatment, production still up 100%+

Challenge
An operator was looking for a solution to enhance oil recovery in a mature conventional oilfield it was operating. Conventional stimulation techniques were considered to address this challenge.
Upon evaluation, they were deemed either not economical, or not applicable, as they had proven ineffective in the past. This was an opportunity for the oil producer to evaluate the BLUESPARK® technology in conjunction with a planned workover on a production well.
Well Conditions
- Depth: 1500 m (5000 ft)
- Temperature: 20 °C (68 °F)
- Porosity: 24%
- Perm: 200 mD
- Glauconite sandstone
Solution
Improve connectivity to the reservoir in cased hole, using electro-hydraulic stimulation technology.
- Mature oilfield production well was treated with Blue Spark BLUESPARK® (Wireline Applied Stimulation Pulsing) technology, to increase production.
- Approximately 1.5 m (5 ft) of perforated interval were treated in the production casing.
- The BLUESPARK® treatment was completed in conjunction with a workover on the oil well. Production rates and fluid levels were both monitored for comparison to pretreatment values.
Outcome
- Client data from the BLUESPARK® treated well showed an average production increase from 9.4 bbl/day to 18.9 bbl/day over a one-month period, based on previous test results, a dramatic 100% increase in just oil production.
- Public data for the next year showed an average of 20.6 bbl/day, a 119% increase.
- The operator will continue to assess opportunities in its production pool to implement BLUESPARK® technology to increase production, in other planned workover activities.
