Concept Study Approach – Concept Study Approach – Marriage of Two OptionsMarriage 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
Pipeline ElementsPipeline 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
Option AOption 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
Option BOption 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

Option C- Potash Industry?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
Pipeline CostsPipeline 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
Treatment of HTreatment of H22SS
• 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
Existing Cost for InjectionExisting 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
What Did We Learn?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
Delivery to Potash Industry?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.)
What is Next?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
