Natural gas development and hydraulic fracturing

  1. 1. Natural Gas Development and Hydraulic Fracturing Sheri Somerville Natural Gas Advisor, CAPP Superport Days 2013 Guysborough, NS July 4, 2013
  2. 2. ● Represents large and small producer member companies ● Members explore for, develop and produce natural gas, natural gas liquids, crude oil and oil sands throughout Canada ● Produce about 90 per cent of Canada’s natural gas and crude oil ● Part of a national industry with revenues of about $100 billion per year ● Associate members provide a wide range of services that support the upstream crude oil and natural gas industry Canadian Association of Petroleum Producers
  3. 3. 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 Environmental Stewardship  Strong regulations  Technology advances
  4. 4. Global Primary Energy Demand IEA New Policies Scenario ● Significant energy demand growth:  Population, standards of living ● Need all forms of energy:  Increasing role for renewables  Continuing reliance on hydrocarbons  Increasing role for non- conventional crude oil & natural gas ● Environmental challenges ● Technology is a key lever for sustainable growth Source: International Energy Agency World Energy Outlook 2012
  5. 5. 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 opportunities continue to emerge (Eastern Canadian shale gas, etc.) *Estimated Recoverable Marketable Gas

  11. 11. Geophysical Exploration (Seismic): Vibroseis truck Seismic charge
  12. 12. Drilling Operations ● Shale gas formations are deep in NB (1,500m to >2,000m) ● Water aquifers are typically 100- 250m deep ● Shale zone accessed through vertical, then directional or horizontal drilling ● 3 layers of steel casing and cement:  Surface casing  Intermediate casing  Production casing
  13. 13. Drilling & Well Construction Wellbores: • Constructed to recover gas while protecting surrounding environment, particularly underground drinking water. • Narrow pipe sunk deep into ground, surrounded by cement in the bore hole to ensure both pipe and underground area it travels through are completely separated. At production site (reservoir), the production pipe is perforated to allow the natural gas to flow into the pipe and rise to the surface.
  14. 14. How does hydraulic fracturing stimulation work? ● Approximately 4,000 cubic metres (4 million litres) of water used to fracture each stage of a well  Water amounts may vary depending on type and location of reservoir.  Total water used at the 4 major shale plays in the USA is less than 1% of total water usage in each state ● Fracture stimulation fluid consists of 98.5% water/sand and 1.5% chemical additives ● All chemical additives are disclosed by industry to regulators before hydraulic fracturing occurs
  15. 15. Fracture Fluid 1.5 % Additives Gelling Agents Cross Linkers Clay Control Breakers Surfactants Biocides Energizers www.fracfocus.ca 98.5% Water & Sand The water, sand, and additives used to convey pressure from the surface to the reservoir to create fractures to be created
  16. 16. Fracture Fluids TYPE Source Purpose Common Use Gelling Agent Guar Gum Polyacrylamide Increase viscosity, helps support and carry proppant better than straight water Food grade product (ice cream, condiments, canned soup, etc.) Found in disposable diapers Clay Control Potassium Chloride Prevents clay from swelling Potash, fertilizer, and table salt substitute Surfactants Naphthalene Lowers surface tension and helps used fracture fluid return to the surface Found in moth balls Windex Biocide Glutaraldehyde (can also be derived from plants or bacteria) Eliminates bacteria from water that can produce corrosive by products Disinfectants, sterilizer for medical and dental equipment Energizers CO2 Nitrogen Improves stimulation or recovery of fluids Odorless, non toxic.
  17. 17. Multi-Well Pads Vertical Well Pad Horizontal Well Pad Advantages 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.

  18. 18. ● 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 taxes What does this mean for Canada?
  19. 19. Each Well: ● Requires 420 individuals working in 150 different occupations to complete and produce gas from one well (directly involved with developing well and placing into production) ● 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: Southwest Pennsylvania Marcellus Shale Workforce Needs Assessment Marcellus Shale Education and Training Center / June 2010 Natural Gas Workforce Information

  22. 22. Guiding Principles for Hydraulic Fracturing 1 2 3 4 5 Safeguard the quality and quantity of regional surface and groundwater resources, through sound wellbore construction practices, sourcing fresh water alternatives where appropriate, and recycling water for reuse as much as practical. Measure and disclose our water use with the goal of continuing to reduce our effect on the environment. Support the development of fracturing fluid additives with the least environmental risks. Support the disclosure of fracturing fluid additives. Continue to advance, collaborate on and communicate technologies and best practices that reduce the potential environmental risks of hydraulic fracturing. We will:
