Two months after completion, oil production declined dramatically on this well. We returned it to production in less than half a day.
75% production increase, sustained for a year
Two months after completion, oil production declined dramatically on this well. We returned it to production in less than half a day.
Challenge
Oil production was lost two months after well completion resulting in only water being produced. As a low volume producer, a cost-effective solution, in conjunction with a workover, was initiated to remediate the well.
Well Conditions
- Depth 450 m (1500 ft)
- Unconsolidated Sandstone
Solution
Improve connectivity to the reservoir by re-initiating worm holes using electro-hydraulic stimulation technology.
- Unconsolidated sandstone (CHOPS) reservoir was treated with Blue Spark BLUESPARK® (Wireline Applied Stimulation Pulsing) to re-initiate production.
- Approximately 2.5 m (8 ft.) of perforated interval were treated with our wireline conveyed tool.
- Treatment was completed in half a day.
- Production rates and fluid levels were both monitored for comparison to pretreatment values.
Outcome
- Worm-holes were re-initiated allowing oil to flow into the well.
- Client data from the BLUESPARK® treated well showed an average production increase from 0 bbl/day pre-stimulation to 5.9 bbl/day for 90 days post stimulation.
- This was a 75% increase over the initial production.
- Sustained production over one year averaged 5.7 bbl/day.
