NAM-IW-111 (Canada West)
CHALLENGE
Well had initially been a producer that was converted to an injector. Injection rate was adequate for 10 years, then sharply declined. The original interval with an additional 20% was re-perfed with marginally better results, but within 2 years the pressures increased and rates dramatically decreased. The client wanted to try a different type of technology to obtain better, longer lasting results.
SOLUTION
Improve connectivity to the reservoir by clearing out blockages using electro-hydraulic stimulation technology.
Unconsolidated sandstone (CHOPS) reservoir was treated with BLUESPARK® to improve injectivity.
No special tools or equipment were required on location to complete the remediation operation, other than third party E-Line.
Approximately 8 m (26 ft) of perforated interval were treated with our wireline conveyed tool.
Injection rates and pressures were both monitored for comparison to pretreatment values.
CONDITIONS
Depth: 650m (2,100ft)
Unconsolidated Sandstone
OUTCOME
The wellbore was reconnected to the reservoir, as pressures decreased and injection rates increased.
Public data from the BLUESPARK® treated well showed an average injection increase from 83 b/d to 289 b/d for 3-months post stimulation.
Sustained injection over more than three years has averaged 54% above initial 10-year rate.
