Acid boosted for 10x production

Key results

• Single-day operation 40ft of perforated interval treated
• 268% increase to oil production after 3-months
• 714% increase to gas production after 3-months
• Sustained increase 250% & 510% average increase of oil and gas production sustained over 12 months post-treatment.

Challenge

The client’s well fluids had dropped by 50% during the past 2 years. Scale deposition was suspected to be in and near the perforations. No remediation had been done in 10 years. The client was planning a workover and required a remediation method that would improve lost fluid flow.

Based on adjacent wells’ production, the client was expecting increases of approx. 5 BOPD and 5 mcf/d gas. Payout was required to be less than 9 months.

• Depth: 9,700 ft (2950 m)
• Temperature: 145 °F (63 °C)
• 1st Bone Spring formation

Solution

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

• The reservoir was treated with BLUESPARK® to re-initiate production losses.
• Approximately 40 ft (12 m) of perforated interval was treated with our wireline conveyed tool during a single day.
• The client ran both the pump assembly and production tubing into the wellbore and began monitoring production rates. An immediate increase in production was observed.

Outcome

• Data from the BLUESPARK® treated well showed a 3-month oil production increase from 6.2to 22.8 b/d (268% increase).
• Gas production increased from 9.8 to 79.8 mcf/d in the same 3 months (714% increase).
• The 12-month average rates correspond to a 250% increase for oil and a 510% increase for gas compared to the pre-stim rates.
• Based on the results, the client is looking for other candidates in the field to remediate.
