# Produced Water Reuse Initiative 2013

Discussion: Comparing the Most Effective Produced Water Treatment Technologies to Date to Derive if an Economical Method has been Found October 29, 2013 Water Recycle & Reuse

## WATER TREATMENT TECHNOLOGIES

! Understanding the minimum levels to which you need to clean produced water for it to effectively support completions fluids

! Stating the different technologies available to understand the processes and chemicals being used to recycle the water

! Examining the costs of differing approaches to ascertain whether successful procedures have also been cost-effective

! Understanding the extent to which recycling water can decrease costs and improve overall economics in the long-run Water Recycle & Reuse

# MINIMUM TREATMENT DRIVERS

Varying Frac Strategies

Slick vs. Gel
Hybrid Frac – both complete and by stage
Testing Strategies – conflicting interests

TDS – Tolerance Levels
TSS – Filtration or Precipitation?
Cleaning Costs are Dropping, Frac Fluids are Becoming More Tolerant
Sterilization Requirements

Chemical vs. Mechanical Kill – Redose vs. Carryover Water Recycle & Reuse

# Water Treatment Technologies/Cost



## Filtration Hydroclone – $.50-1.50 per BBL Chemical Precipitation - $1-3 per BBL Advanced Oxidation - $1-2.50 per BBL Reverse Osmosis - $3.50-5.50 per BBL Distillation/Evaporation - $6-8 per BBL Water Recycle & Reuse

# Economics – Cost Effective?

! What are the true costs of water?

! Direct Costs – Vary by Basin and Producer Strategies

! Purchase, Trucking, Storage, Disposal

! Are These Optimized Now?

! Are There “Take or Pay” Contracts to Overcome?

! Disposal Cost will Continue to Rise

! Indirect Costs

! Water Supply and Price Volatility

! Perceived as Poor Stewards of the Resource

! Trucking Risks: Safety, Road Damage, Dust, Mud

! Long Term Disposal Legal Liability

! The Answer is More Complex than Per Barrel Cleaning Price Water Recycle & Reuse

# After Drilling – Now What?

! Ultimately Rig Counts Will Drop – Water Production will Continue

! Recycle is the Answer Today but What Happens in the Future?

! Clean to Direct Discharge Standards – TDS is the Limiter

! Evaporate, Distill, etc. - VOC’s and Power are the Limiters

! Pretreat to POTW. Regulatory Hurdles and Requires Private – Public Partnerships

! Find New Use – Different Industry? Water Recycle & Reuse

# The Future of Water/Energy
Predictions

The public will have a better understand of the oil and gas energy exemptions. Integrated water-energy policy will be more holistic, not ad-hoc
Water is, and will continue to be, the pinch point for energy exploration/production and refining
Traditional wastewater treatment plants will begin to accept produced water from oil and gas companies.
The nexus point where industrial wastewater treatment meets mobile frac water recycling will be a major sign of integrated water and energy needs in broader alignment – fixed and distributed treatment facilities will grow in capabilities Water Recycle & ReuseBalancing Needs of: Water Consumption, Food Production, Energy & Recreation Oil/Gas Industry
