CONTINUOUS TREATMENT : CASE HISTORY

Anticor DSA 712

Asphaltene dispersant deployment on a North African pilot well

Production without treatment:

  • Discontinuous flow rate, maximum 6.8 m3/hour (1026 bbd).
  • Wire line scrapping every 3 days

Treatment:

  • Formation damage removal by squeeze of Anticor DSA 712 in aromatic solvent
  • Continuous injection of 50 ppm of Anticor DSA 712

Production after treatment:

  • Stable flow rate 8.6 m3/hour (1298 bbd)
  • No more wire line scrapping required

Results:

  • Rise in production:+ 26% = 15 800 m3/year (99 300 bby)
