Breakthrough Oilfield Chemistry
removes oil & gas production zone damage

The global oil drilling industry sustains millions of dollars in lost production annually caused by damage to wells compromised by the deposit of barium sulphate and scales. With Terra Expro’s developments in specialty chemicals, production from damaged gas and oil wells can now be dramatically increased.

Some of the major causes of decreased production are:

• Scaling
• Barite deposition
• Sludge buildup
• Filter cake blockage

Terra Expro’s specialty chemicals provide solutions:

• Barite Dissolvers to remove barium sulphate from production zones
• Calcium and strontium scale removers
• Iron sulphide dissolvers
• Scale removers
• Biological sludge removers
• Mud residue removers

Terra Expro's comprehensive range of specialty oil field chemicals include demulsifiers, inhibitors and tailored scale dissolvers.

Products Prove Themselves in the Field

HDC XREAM freed a TRSCSSV valve on Montrose A-15. Barium sulphate was removed, completely freeing the valve. Production increased immediately by 35% and improved thereafter.

Ferrout 100 removed sulphide scale from the injection mandrel on Douglas platform in the UK. Injection rates immediately increased 38% and were sustained for several months.

Koplus LO + Ferrout 301 removed shale/scale deposits in downhole submersible pumps (ESP) in Indonesia. Prior to treatment common practice was to pull the pumps and replace them. After application of Koplus LO + Ferrout 301 the well was back on production with no ESP overload, doubling previous production. Payback time was 31 hours.
