The successful use of an re-settable inflate test and treat system (RITTS)

In December of 2016 acid selective treatment of open-hole horizontal well had been successfully performed by «Packer Service, LLC» on Kuyumbinskoye oilfield (the Customer is LLC “Slavneft-Krasnoyarskneftegaz”).

In December of 2016 acid selective treatment of open-hole horizontal well had been successfully performed by «Packer Service, LLC» on Kuyumbinskoye oilfield (the Customer is LLC “Slavneft-Krasnoyarskneftegaz”). Pumping conducted with re-settable inflate test and treat system (RITTS) ran on pipe with Rig unit.

Four 20 m3 per each interval stages of acid selective treatment had been performed. Interval between packers equalled 100m with total open-hole length 1100 m (155,6 mm — open-hole).

As per the results of treatment:

  • Re-settable inflate test and treat system (RITTS) application proved to be one of the most innovative solution at selective stimulation of open-hole horizontal wells.
  • Bottom-hole pressure gages’ data confirmed packers’ integrity and existence of the fact of required delta pressure between packers providing treatments’ selectivity
  • Opportunity of interval change between packers (from 10 m to 150m) for optimum interval of treatment selection
  • Possibility of multiple treatments application for one tripping
  • Possibility of running into the hole either with tubing application or with CT
  • Acid fracture treatment performance is recommended for selective treatment provision
  • Either acid fracture treatment or proppant fracture treatment application is possible while multiple-stage re-fracs conducting in horizontal wells (cased wellbore)
