Heating bottomhole area and RCP-proppant placement



Ufa Scientific and Technical Center has developed and patented technical solutions for thermal- chemical well treatment:
  • PSK-3 is an exothermic composition for heating up the bottomhole area
  • PSK-4 is an exothermic composition for heating up the bottomhole area for underpressured reservoirs

Scope of application
  • More efficient placement of RCP in a hydraulic fracture
  • Cleaning the treated well and oil pipelines from paraffins (heavy oil deposits) 
  • Gas depression stimulation (gas lift)
  • Removing gas hydrate plugs

 


PSK-3 COMPOSITION

The heating effect produced by PSK-3 on the bottomhole area is based on the exothermic reaction between two water soluble components

PSK-4 COMPOSITION

The treatment effect of PSK-4 on the near wellbore zone is based on its thermal heating in the result of the heat-generating reaction of the precipitate obtained from compound А and the solvent for the precipitate – compound B
Such process approach guarantees the reaction takes place at the target treatment depth in a well!
