The BaSO4 scale was removed from the sand screens by BLUESPARK®, resulting in an increase in oil production of 175%

The SCSSSV scale was removed by BLUESPARK®, resulting in a successful inflow test and no need for an insert valve

Removed scale from the wellhead using BLUESPARK®, allowing access into the main wellbore.

Removed scale from the upper completion of the wellbore using the BLUESPARK®, treating a 7.5 m (25 ft) interval with an operating time of 6.25 hours.

BLUESPARK® reduced scale by 80 – 100% and saved up to 5 days of operating time and USD $200K. The treatment was completed in one run in less than 14 hours of operating time.

A Tubing Retrievable Surface Controlled Subsurface Safety Valve (TRSCSV) was made operational with BLUESPARK® in 3.5 hours, eliminating the need to shut in the well.

An increase in control line returns was noted after the first BLUESPARK® run, indicating the flow tube and flapper were reactivated. A successful inflow test was performed on the SSSV after the 2nd run.

BLUESPARK® completely removed 40 ft of calcium carbonate (CaCO3) scale from the inside of tubing in less than 2 days, as confirmed by the caliper log.

The SCSSV inflow tests were successful, making the SCSSV compliant and allowing the well to be put back on production. The production of the well was maintained at 3,500 bpd.

Blue Spark Energy successfully performed its first scale removal operation on a Side Pocket Mandrel (SPM) with Gas Lift Valve (GLV) in the North Sea using our innovative BLUESPARK® technology.

Blue Spark Energy successfully performed its first Sub-Surface Safety Valve (SSSV) re-activation in the Danish North Sea using our innovative BLUESPARK® technology.

Post BLUESPARK®, oil production increased 173% from 91.8 b/d to 250.9 b/d. Well uptime increased from 11.8% to 67.8%.
