  1. Latex 3000™ Cement Additive Presenter’s Name

  2. Adequate annular velocity Drilling fluid conditioning Spacers & flushes Pipe centralization Pipe movement Hole size/pipe size relationship Gas/water flow potential Wiper plugs Minimize Rat Hole length Adequate shoe joint length Cementing Operational Considerations

  3. Cement Placement Considerations Addressed by Latex 3000™ Cement Additive • Control gas migration • Improve suspension properties and avoid solids settling • Improve acid resistance of cement slurry • Refrac situations that require old perforations to be squeezed off to enable new perforations • CO2 Injector and Storage Wells • Lower equivalent circulating densities (ECDs)

  4. Conditions Dictated by the Well Mud Weight Mud Viscosity Centralization Annular Diameter Length of Cement Column Conditions Controlled by Operations Pump rate Spacer weight Spacer Viscosity Spacer Volume Cement Weight Cement Viscosity Factors Affecting ECDs When Cementing

  5. Latex 3000™ Additive – Overview • Outstanding rheological properties dramatically lower ECDs • Excellent fluid loss control • Superb suspension properties • Compatible with all current retarders in the Halliburton portfolio • No stabilizer required in Fresh Water, Sea Water, and up to 18% Salt • Salt tolerant with the use of stabilizer in saturated-salt slurries • Resistance to attack by corrosive fluids • Functions at bottomhole circulating temperatures (BHCTs) of 60°F to 400°F (16°C to 204°C) • Lowers permeability of cement • Improved mechanical properties

  16. Latex 3000™ Additive: High Performance / Cost Efficient • Challenge: Provide chemical resistance to cement sheath and casing • CO2 Injector Wells / CO2 Storage Wells • Fresh-water sensitive formations (Shale) • Salt formations (sub-salt ultra-deep water) • Halliburton Solution: new Latex 3000 system • Results – Long-term Zonal Isolation: • Minimizes chemical attack to maintain integrity • Improves resilient properties for Life of the Well

  17. Cement System with Latex 3000™ AdditiveField Results Challenge: Shale Overcome bypassed mud channels and incomplete annular seal due to high ECDs of slimmer profile horizontal wells common in shale wells Solution:Cement system with Latex 3000 additive to achieve sufficient pump rates while managing ECD Results: • Enhanced mud displacement • Optimized cement placement and casing circumference coverage for complete annular seal as indicated by good cement bond logs

  18. Cement System with Latex 3000™ AdditiveField Results Challenge: Utah Re-gain injection profile control by eliminating the dissolution of conventional Portland cement in CO2 flood-injection field Solution: Cement system with Latex 3000 additive • Squeeze cementing Results: • Achieved sufficient rigidity • Prevented flow back to the producing zone • 78% - 100% shut-off to thief zone that had previously stolen the injection gas

  19. Cement System with Latex 3000™ AdditiveField Results Challenge:HPHT Wells / North America Mitigate lost circulation and gas migrationwhen cementing cased wells accessing production zones below depleted zones (intermingled low-pressure and high-pressure zones) Solution: Cement system with Latex 3000 additive • Minimize shrinkage and shorten transition time • Create impermeability to gas migration • Prevent fluid loss with mechanical properties that act like a bridging agent Results: • Fluid losses prevented in depleted zones • Top of cement (TOC) achieved resulting in the pipe being isolated across producing zone

  20. Cement System with Latex 3000™ AdditiveField Results Challenge: Offshore Wells / North Sea • Prevent chronic annulus pressure in newly drilled wells plaguing existing wells in the Elgin-Franklin field Solution: Cement system with Latex 3000 additive • Analysis of predictive failure mechanisms • Designed a cement system with affectively altered mechanical properties such as Young’s modulus, Poisson’s ratio, and tensile strength Results: • The best evaluation of quality remains the absence of sustained annular pressure • Conventional bond log interpretation was inconclusive

  21. Benefits of Latex 3000™ Additive Slurry • Lower Rheologies Results in: • Consistent Pump Rates • Better Mud Displacement • Can be mixed on the fly • Superior Fluid Loss and Free Water Results at BHT • Better Suspension and Stability at BHT • Consistent without the use of stabilizers • Less additives required – More consistent lab results from job to job • Improves resilient properties for Life of the Well • Good expansive properties and ductility
