XCLUDE
• Xclude is a chemical treatment that forms Calcium Sulphate mineral scale in pore throats in the near well bore
• Xclude reduces permeability creating very large skin factors preventing well inflow of fluids
• Scale forms in the reservoir not in the well
• Fluid is bullheaded into the well making application simple, quick and low risk,
• Xclude is safe to people and the environment
• Xclude has the potential reduce P&A costs and risks significantly

Casing Recovery System
• Moderate success rates removing casing with existing P&A and Slot Recovery techniques
• Elastic deformation over an interval of casing breaks the bond and structure of cement on backside
• The Casing Cement Breaker enables longer sections of casing to be pulled reducing trips in and out of the hole – save time and cost
