Less than a day total treatment time, 698% production increase

Challenge

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.

Well Conditions

• Depth: shallow
• Temperature: 25 °C (77 °F)
• Unconsolidated sandstone

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.

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.
