  1. Concept Report / Preliminary Technical and Cost AnalysisDelivery of Treated Produced Water from Indian Basin and Dagger Draw to the Pecos River, Eddy County, New Mexico

  3. Scope of Work • Treatment and Delivery of Produced Water to the Pecos River • #1 Below Brantley Dam • #2 at Dark Canyon • #3 at Malaga Bend • Obtain Preliminary EPA Effluent Limits • Conceptual Design of Treatment Facility • Infrastructure Plan for All Alternatives / Preliminary Maps of Alternatives • Cost Estimates for Alternatives / Compare to Existing Disposal – Injection

  4. Dagger Draw Indian Basin Carlsbad

  5. Pecos Water Quality

  6. Produced Water Quality • 6,500 – 12,000 Total Dissolved Solids • Hydrogen Sulfide – 378 mg/L • NORM – Ra 226+228 – 2500 pC/L • Boron – 2 mg/L • Free Oil – 100 mg/L

  7. Produced Water Cations and Anions • Calcium 685 mg/L • Magnesium 293 • Sodium 3,281 • Potasium 68 • Bicarbonate 1,049 • Sulfate 2,121 • Chloride 4,384

  8. Indian Basin: 70K bbl/dayDagger Draw: 21K bbl/dayAbout the Same Flow as Black River

  9. Concept Study Approach – Marriage of Two Options Scale-up Existing Oil Field Technology/Methods – to 60,000 bbl/day Use Large-Scale Water Treatment Technology Approach and Modify to Meet Produced Water Chemistry Realities

  10. Pipeline Elements • Brantley Dam Alignment • 16 mi • 18-20” diameter • Includes pump station • Dark Canyon Alignment • 27 mi • 20-30” diameter • Gravity pipeline • Malaga Bend Alignment • 51 mi • 20-24” diameter • Gravity pipeline

  11. Option A • Comply with all the effluent requirements identified in the preliminary list from EPA • Treat all the produced water in the area • Evaluate two different sludge handling alternatives • Mechanical dewatering and off-site landfill • On-site sludge lagoon/landfill

  12. Option B • Meet only the TDS requirement of < 5000 mg/L • Eliminate those wells with high TDS concentrations • Treat (RO) approximately 85 percent of the produced water • Include on-site sludge lagoon/landfill • May require creative permits

  13. Proposed Treatment Process FeCI3 Ca(OH)2 Na2CO3 NaOH Backwash Feed Weak Acid Cation Exchanger Cartridge Filters High pH SWRO Walnut Shell Filter IN Lime Softener Multimedia Filtration To Pecos Acid Regen System Belt Press NaOH Regen System Dewatered Sludge for Disposal Backwash Waste Spent Regenerant Waste SWRO Reject Waste Disposal Well

  14. Option A Effluent = 500 mg/L TDS

  15. Option B Effluent TDS = 5000 mg/L

  16. Option C- Potash Industry? • Maybe No Reverse Osmosis to reduce TDS • Hydrogen Sulfide Treatment Required • Petroleum residual treatment? • Pipeline to Carlsbad and connect to existing lines

  17. Pipeline Costs • Pipeline Length (mi) 27.03 • Capital Cost ($) < 26,152,700 • O&M Cost ($/Yr) 8,000 • Cost / Barrel 0.04 • Cost / 1000 gal 0.93 • Cost / Ac-ft 303.00

  18. Treatment of H2S • At this scale, maybe $0.05 - $0.07/bbl • At smaller scale actual H2S treatment is at least 20 cents/bbbl • SWAG of total costs for delivery to potash industry: 10-12 Cents/bbl

  19. Existing Cost for Injection • Capital costs are already amortized (about 10-15 cents/bbl) • O&M costs are about 5 cents/bbl • Gas production is in decline, < 10 years of production remains, no additional capital for disposal • Bottom Line: Treatment and Delivery must meet the 5 cents/bbl existing cost

  20. What Did We Learn? • Treatment and delivery to the Pecos River might have been economically viable BEFORE the oil and gas producers sunk large capital costs for injection • However, must reduce costs below the predicted 32-35 cents/ bbl for Option B • The Tax Incentive (8 cents/bbl for 5 years) is not sufficient to overcome economics

  21. Delivery to Potash Industry? • Might be economically viable IF gas/water production continues for more than 10 years • The Tax Incentive (8 cents/bbl for 5 years) is not sufficient, given the uncertainties of gas and water production • The Government could fund the pipeline, charge for water delivery, and hope for a payback (in water transport fees, by continued agriculture, and > 10 year life.)

  22. What is Next? • Wyoming Coal Bed Methane - Big George • The Next Indian Basin Gas Field • New Treatment Technologies • “Out of the Box” Thinking About Water Management • A Willingness to Sacrifice Some Water Quality for More Water Quantity
