JetSweep™

JetSweep™

JetSweep™ is patented artificial lift downhole tool designed to clean and lift sand or scale from the wellbore during workover and well intervention. JetSweepTM is the first a first for the industry, providing a pressure balanced well vacuuming process that can be deployed using Rig / snubbing unit / CTU assisted sand cleanout operations that can be performed without high fluid losses, and without the expense of multi-string coiled tubing units or nitrogen lift. JetSweep™ is very mature service with more than +300 jobs completed successfully in ME & North America.

JetSweep™ Sand clean out System

JetSweep™ Sand / scale cleanout system offer a major improvement over CTU / CCT cleaning operations to provide effective sand recovery from the wellbore, while cleaning reservoir rock and enhancing oil drainage.

100% wellbore sand/scale cleanout (both Horizontal & Vertical wells).

well’s productivity via cleaning rock matrix & improve permeaEnhancebility.

Extend Artificial lift production system’s life from average by 3 folds.

Extend duration period between well interventions.

Consistent load on Artificial lift production system’s for long period. i.e. Consistent oil production.

Reduce well intervention’s operation Time & Cost.

Reduce significantly well’s production deferment.

“JetSweep™ was announced as winner in SPE2022 (Technology & Innovation category)

best technology for 2022

Application

Sand / scale cleanout

Sand / scale cleanout

JetSweep™ Hydraulics materials are designed to withstand erosive sand production for long period.

Consumed Acid cleanout

Consumed Acid cleanout

JetSweep™ material is designed to withstand sour fluid production.

Well Lifting and Well Testing (Underbalance)

Well Lifting and Well Testing (Underbalance)

JetSweep™ can be used for well Test operation for both balance or underbalance cases as per customer requirements. The same can be used for reservoir’s drawdown for new or old perforation to test reservoir potentials or to clean perforations and filter cakes.

Post-frac sand cleanout

Post-frac sand cleanout

JetSweep™ is used to effectively clean frac sand from the wellbore.

VALUE CREATION & BENEFIT

Operations Optimization

  • It’s proven to our customers that post JetSweep™ has been cut significantly. i.e.: majority of the sandy wells in one of the fields in ME had to be intervened every 6 months in average using conventional methods but after JetSweep™ deployment it become +1.5 years in average.

    Oil Production Deferment

  • The main commercial value when utilizing JetSweep™ is to minimize oil deferment for our client.
  • In busy fields, Client waits for 3-6 months in average to bring the shutdown wells back to production due to sand issue.
  • Minimizing well’s interventions ensure continuous oil production.

    Well's Intervention Frequency Performance

  • It’s proven to our customers that post JetSweep™ has been cut significantly. i.e.: majority of the sandy wells in one of the fields in ME had to be intervened every 6 months in average using conventional methods but after JetSweep™ deployment it become +1.5 years in average

    Asset Integrity

  • Sand production introduced severe damage to production installations and facilities in which maintenance cost and frequency become significant.
  • Sand production cause erosion to tubing, artificial lift systems, production pipes, production stations. This process can be minimized by utilizing JetSweep™ where clean oil production is extended by 2 to 3 times vs conventional methods.

    Well's Production Performance

  • Customer’s feedback post JetSweep™ jobs have indicated production enhancement that varies between 50% to 200%.
  • Some case histories indicated that customers struggled to open up some sandy wells for 3 - 5 years but with JetSweep™ they managed to bring them back to production.
