Organic deposition control

Asphaltenes

• 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)
