CHALLENGE

Client determined that a reduction in total fluid produced was the result of severe scaling of the perforated interval in the Montney formation. This build-up of scale was confirmed to be Calcium Carbonate. Previous acid treatments had little effect in removing the scale deposition to improve production.

SOLUTION

Improve connectivity to the reservoir using electro-hydraulic stimulation technology.

  • BLUESPARK® technology was run on third party wireline.

  • A 2m (7ft) interval was stimulated with a total operating time of just over 2 hours.

  • The well was placed back on production and an immediate sustained increase in production was observed.

  • After 45 days of sustained production the customer successfully acidized the well with outstanding results.

Blue Spark Energy case study - build of scale of calcium carbonate

CONDITIONS

  • Depth: 1900m (6200ft)

  • Temp: 65 °C (150 °F)

  • Formation: Montney Shale

OUTCOME

  • Client data from the BLUESPARK® treated well showed an increase from 2.2 bbl/day (0.35m3/d) of oil to 5.9bbl/day (0.93 m3/d) in the first 45 days post-stimulation.

  • After complementary matrix acidizing, the oil rate increased further to an average of 13.1 bbl/day (2.09 m3/d) for the next 53 days.
