PinPoint re-stimulation using SurgiFrac® Service

Challenge

• A gas producer well in the UAE was completed with a 7,000 ft horizontal section, that required a stimulation treatment to restore production
• Bypassed pay remains accessible
• The lateral is an open hole, making selective placement of stimulation intervals and limited treatment volumes, critical to bypass the depleted zones
• Upper completion casing has a maximum pressure limit of 4,700 psi

Solution

• The target stimulation depths were selected based on petrophysical analysis of the logs performed on the open hole
• SurgiFrac^® was selected as the stimulation method to enable targeted placement of treatments, utilizing dynamic diversion to provide pressure isolation
• Primary treatment pumped down the CT string would allow optimal stimulation, not exceeding the surface casing pressure limits

Result

• Operation was completed in less time than anticipated by the customer, completing 20 stages in 24 hours
• Dynamic diversion enabled the placement of separate targeted stimulation intervals in an open hole completion, bypassing depleted zones
