Strong Global Shale Interest Expanding interest in repeating North America shale energy New global energy paradigm emphasis since Paris. Gas?? New markets for U.S. gas pipeline & ship Greater pairing with renewable technologies
Shale Energy Developments Geopolitical -- 80% of shale gas is in locations with 30% of conventional gas resources EU diversification shale development(uk), LNG Commercial production in Argentina and China In U.S., increasing quantities of NGLs and dry nat gas Substantial increase in reserves and utilization New exports of NGLs --Propane/Ethane 74 Bcf/d --27+ Tcf/yr Currently 50%+ of dry gas production from shale Large need for infrastructure midstream/roads/people U.S. -commercially predictable regulatory environment

Drilling Trends in North America Shorter time to drill a well Months to weeks to days(currently) -30 to 50% increase in efficiencies Costs decreasing Water transport and remediation Move to walking rigs built for purpose Longer wellbores -- 6000+ meter lateral in OH More frac stages and move to target best rock(40% yields 80%) More proppant almost doubled from recent past Every frac is a unique effort matching pressures to rock Upgrades to subsurface technical expertise/technology Increased gas volumes per lateral Increased IPs/EURs/ROR flatter declines
Conveying Benefit vs. Risk What are the reasons for producing the energy Demand for all energy Economic rewards New commercial and industrial development --utilization Workforce opportunities Bridge to something else Fossil vs. renewables all the above strategy Geopolitical opportunity Environmental climate What are the risks Separating possible vs. probable risk with all energy dev l Wellbore integrity Water contamination Chemicals Methane Air emissions Health Climate Gaps in research??
Appalachian Basin Background Challenging regional dialogue Environmental Political Regulatory Public engagement Shale revolution brought energy development to non-traditional areas Heightened public awareness -- social media New advocates/opponents Opposition has migrated to larger infrastructure Public policy spanning traditional politics
Non Legacy Development
Greater Stakeholder Engagement? Community of impacted stakeholders has changed Local interest and implications global influence, distant ownership So who to engage? Who is the citizen? Social media has changed the rules, critical now Need to create social license Everyone connected in mobile world Expectations for a shorter message Need to address concerns Science-based response Transparent process
Social License to Operate What constitutes social license Who gives it? And who can take it away? How are unique concerns of indigenous communities addressed Increasing levels of environmental activism Social justice What is it? Maximizing benefit Misinformation via impacts of social media
Dialogue of Science or Politics? Importance of baseline risk assessments Environmental Socio-economic Demographics in impacted region Human health trends What order? Assessment vs. permitting. Who has the science that counts Who funds the research A new climate based threshold Do we make policy decisions on science? NY/EU

Power Generation Trends Coal and NG trading spots for top U.S. power gen fuel permanent?? 31.2 bcf/d of U.S. total for power(may 16) 5,000 total MW installed since 2013 in U.S. mid-atlantic PJM market 15% of coal gen offline by 4Q16 20 yr low in CO2 emissions Nat Gas paired with renewables Pipeline constraints?? Bias towards single fuel? Greater onshore production Reduced offshore extreme weather price impacts
Petrochemical Trends $164 B in new investment planned in U.S. Largely shale gas driven Recent announcement by Shell for ethylene production in Marcellus/Utica region. Large quantities of ethane New manufacturing capacities planned $105 B/yr contribution to economy predicted Significant workforce additions 700K+?? Competition with oil-linked, lower cost naphtha Low cost Middle East producers Ethane exports to Norway and Scotland New export markets needed collectively Other energy intense industrial utilization

Workforce Trends The direct workforce to drill a single well 420 individuals working in 150 different occupations Each well requires 13.09-13.29 FTE workers annually Overall Creates roughly 24,271 30,218 direct job FTE s by 2014 Indirect and induced are significant in shale regions (1.52X) Multi-Well pads Now standard industry practice Reduces the overall environmental footprint Reduce the number of jobs required during pre-drilling and drilling phases of development Recent Utica research shows reduced workforce due to new efficiencies in drilling, water use
Workforce and Business Trends Localizing the worker 75% blue collar/technical Front loaded on well s lifecycle Matching demand to availability of labor Institutional capacity to train and not overproduce Housing requirements and required infrastructure Key part of social license
