INDUSTRY TRENDS BENEFITS

Improving Fracturing Chemistry Increasing use of non-fresh water

Innovation in TreatmentTechnology

Increasing feasibility of produced water reuse

Increasing Water ConveyanceSystems

Reducing truck traffic

New Water Storage DesignsProvides flexibility and reliability when using non-fresh water

Increasing TransparencyImproves relationships with stakeholders

Dedicated Water StaffImproves water management, planning technical support and performance


TREND 1: Development and improvement in fracturing chemistry enables industry to use non-freshwater

Fracturing methods: slickwaterversus crosslink

Engineers select the method based on multiple variables

Water quality and quantity variesCrosslink: higher quality, less volumes

Slickwater: lesser quality, higher volumes

Reservoir characteristics and well design vary by region and will affect volumes of water

TREND 1: Development and improvement in fracturing chemistry enables industry to use non-freshwater

Water sources vary by region

Regulatory programs vary by state

Increased use of brackish water in oil and natural gas

Innovations in hydraulic fracturing have enabled E&P companies to be less reliant on freshwater sources and expand options in water-stressed areas such as these brackish wells used by Devon Energy. Photos Source: Devon Energy

TREND 2: Treatment technology innovation continues to make produced water reuse more feasible

Increased viability of use of produced water

Operators are better able to use lower quality water due to technological improvements

Treatment of produced water is an option in certain circumstances

Pioneer Natural Resources partnered with a startup company with a new carrier gas extraction (CGE) process that desalinates produced water with less energy and lower operating costs than comparable commercial technology. The first-of-its-kind plant was designed and installed quickly. The plant treats water for reuse, and the CGE process reduces total dissolved solids (TDS) from about 120,000 parts per million (ppm) to about 500 ppm. Photo source: Pioneer Natural Resources USA

TREND 3: Improvements in water conveyance for gathering and distribution reduce truck traffic

Companies are increasingly using pipelines

Decreasing truck traffic, road impact, and safety issues

Temporary lines can be used for short term needs

Systems need to be flexible

Layflat hose provides compact, large capacity pipe

TREND 4: New water storage designs provide flexibility and reliability in alternate non-freshwater sourcing

Steel fracturing tanks, and in ground, modular, lined, and monitored impoundments used to store fresh and produced water

New designs provide flexibility for quantity stored

Type of storage unit can be influenced by surface owner, regulations and topography

TREND 4: Water storage technologies

Industry practices prevent leaks, protect groundwater, and safeguard the environment

Advances in the design of large storage systems address variables

Slopes, soil composition, moisture control

Dual liners, sump, liner thickness, covers, monitoring wells

TREND 5: Transparency improves relationships with communities, industry and regulators

15

National registry managed by Ground Water Protection Council (GWPC)

Over 85,000 disclosures to FracFocus (2011-2014)

Chemical Disclosure Required

Chemical Disclosure Being Proposed

States Currently Using FracFocus

States Considering FracFocus

Hydraulic Fracturing Chemical Disclosure State-by-State 7/1/2014


TREND 5: Transparency improves relationships with communities, industry and regulators

Corporate responsibility is reflected in self-imposed measurement and tracking water

Increased data gathering and public disclosure

Water management strategies can be influenced by landowner agreements

State regulations cover all aspects of water management

EWI is an example of industry collaboration

16


TREND 6: Dedicated water staff within E&P organizations improve water management planning, technical support and performance

17

EWI companies are creating dedicated internal resources and teams to facilitate water management

It can range from:Developing a separate entity

Centers of excellence

Specific water teams

Companies are centralizing lessons learned, establishing standards, identify subject matter experts


EWI Encouraging Research

EWI invites universities, agencies, and companies to present on technologies and research

Future research can focus on:Advancing treatment technologies and processes

Improving on analytical methodologies

Enhancing measurement and management of water

EWI is encouraging increased research funding into advancing water treatment technology

18


Water Programs Can Include:Outreach to build stakeholder confidence

Collaboration with other operators

Building infrastructure improvements to meet partner needs

Innovating for regional water benefits

Recycling and reusing to conserve and maximize water

Building efficient redundancy and reliability into the system

19


1. Manage water to support oil and natural gas production

2. Make beneficial use of all water supplies (fresh, flowback, produced) for full water lifecycle

3. Reduce trucking traffic across region

4. Decrease dependence on saltwater disposal wells

5. Reduce demand for fresh water supplies

6. Maximize use of existing facilities and infrastructure

7. Reduce energy demands

8. Enhance social license and environmental stewardship
