NAM-NW-106 (Canada West)
CHALLENGE
The need for additional fresh water in Northern Alberta, Canada, to support ongoing SAGD (steam-assisted gravity drainage) –type production. A cased hole completion with a wire-wrapped sand screen and a gravel pack completion with an ESP pump, failed to yield expected desirable rates of water production. Known remediation techniques were reviewed and deemed unsuitable.
SOLUTION
Improve connectivity to the reservoir through a wire-wrapped sand screen gravel pack completion, using electro-hydraulic stimulation technology.
In consultation with our client, the well was evaluated to confirm its suitability in terms of temperature and other factors, and subsequently treated with our BLUESPARK® technology.
Approximately 20 m (65 ft.) of sand screen were treated with our wireline conveyed tool.
No special tools or equipment were required on location to complete the remediation operation, other than third party E-line.
The remediation treatment took less than one day to complete, with immediate, significant, and sustained rates observed during production testing conducted shortly thereafter.
CONDITIONS
Depth: Shallow
Temperature: 25 °C (77 °F)
Unconsolidated sandstone
OUTCOME
Client data from the BLUESPARK® treated well showed an average production increase from 100m3/d (630 b/d) to 800m3/d (5,032 b/d) over a one-month period.
Sustained production over 90 days maintained an average of 800 m3/d (5,032 b/d).
Client is evaluating the continued use of electro-hydraulic stimulation in other similar source wells, especially where inflow expectations are not being met.
