  1. UniStim™ Hydraulic Fracturing Fluid System–A Universal High TDS X Link Recycle Fluid

  2. H2OForward℠ Service –An Integrated Approach to Turn a Waste Stream Into a Revenue Stream Without Risking Production • Effective Water Treatment • Fluid Formulation (High TDS) and Scale Modeling • Effective Biocide • Efficient Logistical Engineering for Well Construction

  3. Halliburton Frac Fluids

  4. History of Halliburton Water-Based Frac Fluids and Services

  5. UniStim™ Hydraulic Fracturing Fluid System – What is it? • High performance hydraulic fracturing fluid system that enables operators to use 100% produced or flowbackwater • Crosslinked gelled water system that has the ability to tolerate salt concentrations in excess of 300,000 ppm, as well as other contaminants

  6. UniStim™ Hydraulic Fracturing Fluid System – Advantages • Clean • Low residue • High regained conductivity • High regained core conductivity • Efficient • Excellent proppant transport and suspension • Versatile • Wide temperature range 100-275°F • Salt tolerant • Instant and delayed crosslinking • Can be foamed with CO2 • Available • Dry powder (FDP-S1096-13) or LGC

  7. Delaware Basin Customer Using 100% CleanWave® System Treated Produced Water on 8 Wells – 98 Stages 100% CleanWave System Treated

  8. 100% CleanWave®System Treated Water 270,432 ppm TDS with UniStim™ Fracturing Fluid 100% CleanWave Treated 100% CleanWave System Treated

  9. Bakken – 100% WilcoSWD (Produced) Untreated and CleanWave® System Treated Water Analysis

  10. Bakken SWD – CleanWave® Treated 100%25 lbUniStim™ Frac Fluid at 200°F 25# UniStimFrac Fluid – 100% CleanWave Treated Produced

  11. Bakken – 100% CleanWave® Treated Water 299,160 ppm TDS with UniStim™ Frac Fluid High TDS – CLIP

  12. UniStimSMFrac Fluid Service Usage in Permian and Bakken • 60 wells • 260 stages • >270,000 TDS Source: USGS

  13. Challenges Addressed Using 100% Recycled Water • Meet the needs of a growing fracturing market • CleanWave® system treated 17,777,428 gallons of 100% produced water for 60 different wells for a total of 260 stages frac completions. • Success on all 260 stages in water >270,000 TDS with no crosslink issues and no scaling issues • No production decrease vs. fresh water • Avg. savings $100-200K per well HAL37313

  14. H2OForwardSM Service BENEFITS • Consistent with HSE culture and expectations • Economic and environmental benefits vs. once through use of fresh water • Defined ownership lines within one team • Improved communication and continuity • Understanding of water constituents and corresponding impact on selected fluid recipe • Knowledge and control of additives selected • Extensive laboratory testing capabilities which is part of this service • Ensuring fluid integrity and well productivity are not jeopardized

  15. 2013 SPE Papers on High TDS Recycle Produced Water • SPE #163824 “Development and Use of High TDS Recycled Produced Water for Crosslink-Gel Based Hydraulic Fracturing” • SPE #165085 “Effects of Total Suspended Solids on Permeability of Proppant Pack” • JPT Magazine Technology Update – June 2013 “Treatment Enables High-TDS Water Use as Base Fluid for Hydraulic Fracturing” • SPE # 165641”Recycling Water: Case Studies in Designing Fracturing Fluids Using Flowback, Produced, and Nontraditional Water Sources”
