  3. Project Results(Budget Phase 1) • Defined Mud Types and Properties suitable for MHT • Defined Hydraulics Geometries and Conditions for MHT - Set envelope of operating parameters • Developed Abrasive Slurry Jet (ASJ) Drilling System • Evaluated and Identified Pumps suitable for MHT and ASJ • Evaluated and Identified Mud Processing Equipment suitable for MHT and ASJ • Explored non-traditional components and methods for the Mud System

  4. and Well control

  5. MHT Mud System Specifications • Hole Specs: 3.5” hole; 5000’ TVD; 1000’ lateral • Pump Flow Rate and Pressure Specs: 300 gpm @ 1000 psi; 10 gpm @ 5000 psi • Flow Back Processing Specifications: 500 gpm water based, oil based and gasified fluids • Other Parameters: • Mix, circulate, clean and store 200 bbls water / diesel muds • Mud- types/function • Zero Discharge – “no fluids hit the ground” and “solids / liquids can be hauled” • HSE Considerations

  6. Kemtron KTL48 Dual shaker Dual cones

  7. Mud System Evolving Technologies • Abrasive Slurry Jetting - ASJ • High Pressure Slurry Pump • Modular non-steel tank & piping • Composite Coiled Tubing • Sintered Carbide Surfacing • Grind, Slurry & re-inject fluids & cuttings • Clear water only discharge • GLCC plus • Horiz Directional Drilling/ Trenchless • Ground TPO Liner

  8. Results and Discussion • Pumps Evaluated • Kerr 3500 series • National JWS185 • Gardner Denver TEE series • Tulsa Triplex TT series
