5 wells all see production increases

Key results

• Gravel packs, slotted liner
• 5 well campaign treated in 5 days
• 65% increase in total production – after 3 months
• Sustained increase, 62% total production after 12 months

Challenge

The client operates a small field under steam flood with declining oil production. Conventional stimulation techniques such as acid had yielded mixed and/or short term results. The client was interested in trying a cost effective technology that would potentially provide better and/or longer lasting results.

• Depth: 650 ft (200 m)
• Etchegoin Sandstone
• Porosity 35%; Perm 5 D

Solution

Improve connectivity to the reservoir through a slotted liner using electro-hydraulic stimulation technology.

• The client chose 5 wells to treat with BLUESPARK® to improve production.
• The client selected the treatment zones from open hole logs, such that the total interval stimulated could be maximized in a single day of operation for each well.
• Tubing was pulled and a bit-and-scraper run was done on each well.
• The BLUESPARK® stimulation was completed on all 5 wells in 5 working days.

Outcome

• The wells were immediately put back on production and rates, pressures and fluid levels were monitored.
• The total production for the 5 wells increased by 65% based on a 3-month comparison, while the water cut decreased by 5%.
• Three of the wells saw increases of over 100%.
• The total production for the 5 wells maintained a 62% increase for the 12-months following the stimulation.
