BJ S3 Acid SM System Case Example - Malaysia

• Scale removal and inhibition required
• Well history of rapid production decline due to
  CaCO3 scale build-up in wellbore
• One-step S3 Acid treatment conducted to stimulate
  oil production and
• Prevent rapid post-acidizing production rate
  decline

MalaysiaTreatment Results

• Rate before treatment 500 bopd (April 2001)
• Rate after treatment 900 bopd (stabilized)
• Objective accomplished
• Sustained production rate

10
BJ S3 Acid SM System Case Example - Indonesia

• Scale removal and inhibition required
• Well history of scale removal with HCl acid
• Rapid post-acidizing production decline following
  HCl acid treatment due to re-formation of
  calcite scale - 4 jobs performed before
• S3 Acid treatment conducted to stimulate oil
  production and inhibit scale re-formation
