Natural Gas Developmentand Hydraulic FracturingSheri SomervilleNatural Gas Advisor, CAPPKV Chamber of CommerceJune 5, 2013
Presented ByThe Canadian Associationof Petroleum Producers(CAPP)New Brunswick O&NGTask GroupThe New Brunswick Oil &Natural Gas Association(NBONGA)
● Represents large and small producer member companies● Members explore for, develop and produce natural gas,natural gas liquids, crude oil and oil sands throughoutCanada● Produce about 90 per cent of Canada’s natural gas andcrude oil● Part of a national industry with revenues of about $100billion per year● Associate members provide a wide range of services thatsupport the upstream crude oil and natural gas industryCanadian Association of Petroleum Producers
● In 2011 the NBONGA was formed to facilitate the effectiveexploration, development, production, transmission anddistribution of New Brunswick’s hydrocarbon resources inan environmentally safe and responsible manner● In December, 2011 the NBONGA and CAPP joined to form aTask Group● The Task Groups objective is to engage with communities,business leaders, governments and people interested in anopen, fact-based dialogue about natural gas and oildevelopmentWhat is the NB Oil & Natural Gas Association?
Advancing the 3Es the 3Es● Generating Economic Benefits Jobs and revenues across North America● Providing Energy Security Safe, secure and reliable energy Large energy resource potential● Providing EnvironmentalStewardship Strong regulations Technology advances
Global Primary Energy DemandIEA New Policies Scenario● Significant energy demandgrowth: Population, standards of living● Need all forms of energy: Increasing role for renewables Continuing reliance onhydrocarbons Increasing role for non-conventional crude oil & naturalgas● Environmental challenges● Technology is a key lever forsustainable growthSource: International Energy Agency World Energy Outlook 2012
How will demand be met?Technological advances have unlocked vast unconventional gas resources.Resource assessments are ongoing (GSC, NEB and others) in many new areas, and new opportunitiescontinue to emerge (Eastern Canadian shale gas, etc.)*Estimated Recoverable Marketable Gas

Natural Gas and OilIndustry in NewBrunswick:● First oil well drilled atDover in 1859● 300 oil and gas wells weredrilled in NB by 2010● Since 1990, 40 oil wellsdrilled and 40 Natural Gaswells● 29 natural gas and 18 oilwells are currentlyproducing● Since 1990, 49 wells havebeen hydraulicallyfractured for oil and gas inNB

Stages of Exploration and Production forUnconventional ResourcesNova Scotia Duvernay Horn River MarcellusNew Brunswick
Drilling Operations● Shale gas formations are deep inNB (1,500m to >2,000m)● Water aquifers are typically 100-250m deep● Shale zone accessed throughvertical, then directional orhorizontal drilling● 3 layers of steel casing andcement: Surface casing Intermediate casing Production casing
Drilling & Well ConstructionWellbores:• Constructed to recover gas whileprotecting surroundingenvironment, particularlyunderground drinking water.• Narrow pipe sunk deep intoground, surrounded by cementin the bore hole to ensure bothpipe and underground area ittravels through are completelyseparated.At production site (reservoir), theproduction pipe is perforated toallow the natural gas to flow intothe pipe and rise to the surface.
How does hydraulic fracturing stimulation work?● Approximately 4,000 cubicmetres (4 million litres) of waterused to fracture each stage of awell Water amounts may varydepending on type and location ofreservoir. Total water used at the 4 majorshale plays in the USA is less than1% of total water usage in eachstate● Fracture stimulation fluidconsists of 98.5% water/sandand 1.5% chemical additives● All chemical additives aredisclosed by industry toregulators before hydraulicfracturing occurs

Multi-Well PadsVertical Well Pad Horizontal Well PadAdvantages of Multi-Well Pads:• Reduction of land use for the pad, access roads & pipelines.• Easier monitoring of site and enforcement of regulations.• Conducive to establishing and enforce traffic/trucking corridors.• Optimization of location.• Establish and enforce noise, light, air emission and water plans.Source: ERCB 2011
● Jobs (Upstream from Western Canada Natural Gas)Natural Gas industry employment: 317,000 – jobs (direct, indirect and induced) across Canada by 2035 9,693,000 – person years of employment between now and 2035 $339 billion – natural gas employees will earn over next 25 years● Revenue, Royalties, Taxes (To all Canada from Western Can. NG)Natural Gas industry will: contribute $1.5 trillion to Canadian GDP over next 25 years generate $199 billion in royalties generate $170 billion in federal taxes generate $130 billion in provincial taxesWhat does this mean for Canada?
Each Well:● Requires 420 individuals working in 150 different occupations to complete andproduce gas from one well● Creates approximately 13 Direct FTE’s per year● Creates 32 – 58 FTEs per well, if you include direct, indirect and induced jobs(varies by jurisdiction)Source: Marcellus Shale Education and Training CenterNatural Gas Workforce Information

Guiding Principles for Hydraulic Fracturing12345Safeguard the quality and quantity of regionalsurface and groundwater resources, through soundwellbore construction practices, sourcing fresh wateralternatives where appropriate, and recycling waterfor reuse as much as practical.Measure and disclose our water use with the goal ofcontinuing to reduce our effect on the environment.Support the development of fracturing fluid additiveswith the least environmental risks.Support the disclosure of fracturing fluid additives.Continue to advance, collaborate on andcommunicate technologies and best practices thatreduce the potential environmental risks of hydraulicfracturing.We will:

Who Regulates Oil & Natural GasSector● Federal & Provincial Departments Environment (Environment & Local Government) Energy (Energy & Mines) Natural Resources Transportation Fisheries and Oceans (Agriculture, Aquaculture &Fisheries) Finance Public Safety Others may be involved: Aboriginal Affairs,Economic Development● Federal & Provincial regulatory entities: National Energy Board (NEB) Energy and Utilities Board (EUB)● Federal Programs: Chemicals management program New Substances program
The New Rules in NB Seismic testing procedures (e.g.,minimum setbacks 180 m) Well bore construction, casing,containment, testing, etc. (e.g. doublewell casings) Managing wastes and potentialcontaminants (e.g., closed loopsystems for drill fluids) Monitoring to protect water quality(e.g. water well testing, surface watermonitoring) Sustainable use of water (e.g., watermanagement plan and reporting) Air Emissions and GHGs (e.g.,monitoring, emissions reduction plans) Public safety and Emergency Planning(e.g., CSA compliant-EmergencyManagement program) Communities and the environment (e.g.,traffic plans, noise, water supplies) Reducing financial risks and protectinglandowner rights (e.g., financial securityfor damage) Sharing information (e.g., disclosure offracture fluids)Responsible Environmental Management of Oil and Natural Gas Activities
Responsible Energy Development● New Brunswickers & Canadians want to knowthat shale gas can and will be developed safely● Strong regulation that has worked successfullyin Canada can provide framework for emergingprovinces● Companies are committed to:• Responsible energy development and abide bycodes of conduct that further supports strongregulation• Accountability and transparency• Strong regulatory frameworks, enforcement policies• Scientific research and continuous improvement● Natural gas is a significant opportunity withpositive effects on economy and energy supply.Support the Responsible Exploration andDevelopment of Natural Gas in NB
