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

Subsea Laser Cutting Objectives
500m sea water depth
Electrical control and drive
Improved cutting times
Reduced carbon footprint
Reduced equipment mobilisation

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

Depth
• Increase Depth and Pressure range
Temperature – Heat Exchanger
• Lower Temperature & higher Viscosities (µoil).
• Heat exchange efficiency in oil
HoT tap Diameter
• Increase drill core diameter
• Insert larger tools (e.g. HX / Dredger)
• Increase flow capacities
