NAM-OH-107 (Canada East)
CHALLENGE
The reservoir had sustained skin damage during the drilling process, and a remediation was required. Previous acid stimulation had resulted in negligible well production increases and caused lower borehole collapsing due to matrix dissolution.
With a ban on conventional hydraulic fracturing, the client was looking for an alternative but effective remediation option.
SOLUTION
Improve connectivity to the reservoir in open hole, with electro-hydraulic stimulation technology.
In consultation with our client, the wellbore candidate was confirmed, and subsequently treated with BLUESPARK® technology.
Approximately 58m (190 ft) of open hole were treated with our wireline conveyed tool.
No special tools or equipment were required on location to complete the remediation operation.
Evaluated production rates pre- and post-stimulation to determine success.
CONDITIONS
Depth: Shallow
Formation: Unconsolidated sandstone
Temperature: 25 °C (77 °F)
OUTCOME
Pre- and post-stimulation image data comparison (electrical resistivity) on a single producing wellbore confirmed that electro-hydraulic technology created fractures in the near wellbore region.
Client data from the BLUESPARK® treated well showed an average increase in oil production of 96 b/d over a one month period.
Sustained oil production over 90 days maintained an average of 90 b/d.
Client is evaluating the use of electro-hydraulic stimulation in other tight oil reservoir environments, especially where acid-stimulations failed.
