The National Energy Board (the NEB or the Board) is an independent federal regulator whose purpose is to promote safety and security, environmental protection and efficient infrastructure and markets in the Canadian public interest[1] within the mandate set by Parliament for the regulation of pipelines, energy development, and trade.
[1] The public interest is inclusive of all Canadians and refers to a balance of economic, environmental, and social considerations that change as society's values and preferences evolve over time.
The Board's main responsibilities include regulating the construction and operation of interprovincial and international oil and gas pipelines, international power lines, and designated interprovincial power lines. Furthermore, the Board regulates the tolls and tariffs for the pipelines under its jurisdiction. With respect to the specific energy commodities, the Board regulates the export of natural gas, oil, natural gas liquids (NGLs) and electricity, and the import of natural gas. Additionally, the Board regulates oil and gas exploration and development on frontier lands and offshore areas not covered by provincial or federal management agreements.
The Board also monitors energy markets, and provides its view of the reasonable foreseeable requirements for energy use in Canada having regard to trends in the discovery of oil and natural gas[2]. The Board periodically publishes assessments of Canadian energy supply, demand and markets in support of its ongoing market monitoring. These assessments address various aspects of energy markets in Canada. This Energy Market Assessment (EMA), Short-term Canadian Natural Gas Deliverability, 2012–2014, is one such assessment. It examines the factors that affect natural gas supply in Canada in the short term and presents an outlook for deliverability through 2014.
[2] This activity is undertaken pursuant to the Board's responsibilities under Part VI of the National Energy Board Act and the Board's decision in GHR-1-87.
While preparing this report, in addition to conducting its own quantitative analysis, the NEB held a series of informal meetings and discussions with natural gas producers, pipeline companies, and industry associations. The NEB appreciates the information and comments provided and would like to thank all participants for their time and expertise.
If a party wishes to rely on material from this report in any regulatory proceeding before the NEB, it may submit the material, just as it may submit any public document. Under these circumstances, the submitting party in effect adopts the material and that party could be required to answer questions pertaining to the material.
This report does not provide an indication about whether any application will be approved or not. The Board will decide on specific applications based on the material in evidence before it at that time.
This report provides an outlook for Canadian natural gas deliverability[3]from the beginning of 2012 to the end of 2014.
[3] Deliverability is the estimated amount of gas supply from a given area based on historical production and individual well declines, as well as projected activity. Gas production may be less than deliverability due to a number of factors, such as weather related supply interruptions, and shut-in production due to economic or strategic considerations.
Major factors influencing deliverability over this period include:
[4] NGLs are liquid hydrocarbons including propane, butanes, and pentanes plus. Natural gas containing commercial amounts of NGLs is known as NGL-rich, liquids-rich or wet gas. Dry natural gas contains little or no NGLs. Gas produced from oil wells includes gas in solution within the oil (solution gas) and gas adjacent to the oil within the reservoir (associated gas). Production of solution gas and associated gas is almost entirely dictated by oil operations, and is typically not influenced by natural gas market conditions.
These important factors have diverted investment and drilling activity away from targeting dry natural gas in Canada and the U.S., and will likely cause Canadian deliverability to decline over the projection period. Total Canadian natural gas deliverability will continue to be well above the level of Canadian demand.
Recognizing the uncertainty associated with future natural gas prices, this report examines three price cases for Canadian natural gas deliverability.
The Analysis and Outlook section of this report contains the key assumptions for each price case.
The Appendices contains a detailed description of the methodology used in projecting deliverability.
The Canadian and U.S. natural gas supply has been affected by recent growth in natural gas production. Highlighted below are key factors that have shaped expectations regarding future deliverability.
[5] Marketable (sales) gas is gas that has been processed to remove impurities and NGLs, and meets specifications for use as an industrial, commercial, or domestic fuel.
[6] The Canaport terminal in New Brunswick is the only operating liquefied natural gas (LNG) import terminal in Canada. Since gas supply for LNG projects comes from outside the country, LNG imports are not included in this report on Canadian gas deliverability.
Key supply and demand drivers influencing future Canadian natural gas deliverability include:
[7] Fracturing is a technique in which fluids are injected underground, in multiple stages, to create or expand existing fractures in the rock, allowing oil or gas to flow out of the formation, or to flow at a faster rate.
A decline in natural gas drilling activity is expected over the projection period in the Mid-Range and Lower Price Cases. The Higher Price Case will see a decline in drilling activity before increasing in 2014. As natural gas drilling activity slows while Canadian and U.S. demand increases, natural gas prices may begin to trend upward, eventually providing the incentive for additional natural gas drilling. The timing and degree of this transition from declining to increasing natural gas activity is uncertain. To help address the uncertainty, this report examines three price cases for Canadian natural gas deliverability. These cases differ primarily in terms of Canadian and U.S. natural gas prices and the corresponding levels of capital investment. The cases also vary in terms of drilling levels targeting wet gas and dry gas, particularly in the Montney play of Alberta and B.C., and Horn River Shale prospects in northeastern B.C. The Appendices contain a detailed description of the methodology used for projecting deliverability. The cases are:
A summary of the key assumptions used in the cases and the deliverability results is shown in Table 4.1:

For this analysis, the Board divides natural gas production in Western Canada into conventional, coalbed methane (CBM), and shale gas categories. Within the conventional gas category, there is a sub-category called tight gas. Due to large regional differences in physical and producing characteristics, the Board further subdivides these categories into smaller geographic areas, or regions, which have similar characteristics for production decline analysis. Within each region, grouping of the producing formations takes place on a geological basis. Details on the characterization of the resources are available in Appendix B. Canadian natural gas production outside of Western Canada includes:
The three price cases cover a range from a Lower Price Case where almost all drilling of natural gas is uneconomic unless the gas has a high NGL content, to a Higher Price Case where natural gas supply and demand move into balance and provide an incentive for the resumption of dry natural gas drilling. A Mid-Range Price Case is largely reliant on activity targeting NGL-rich gas as prices do not reach levels that would support much drilling for dry natural gas. A comparison of the three Canadian natural gas deliverability outlooks to 2014 under these alternative market conditions is shown in Figure 4.1.
Figure 4.1 - Deliverability Results
The levels of drilling activity that provide these deliverability outcomes are the result of capital investment assumptions and estimates of drilling costs. A comparison of natural gas drilling activity in the three cases in terms of drill days and gas-intent wells drilled are shown in Figure 4.2 and Figure 4.3, respectively.
Figure 4.2 - Natural Gas-Intent Drill Days Comparison
Figure 4.3 - Natural Gas-Intent Wells Drilled Comparison
For the Mid-Range Price Case, oversupply conditions continue to drive 2012 Canadian and U.S. natural gas prices below those experienced in 2011. After 2012, prices gradually rise, but not enough for much dry gas drilling to become economic. Producers would continue to reduce natural gas drilling, particularly for dry natural gas. With a decrease in overall natural gas drilling, Canadian production declines, and U.S. production growth slows. The demand for natural gas slowly increases, and as the amount of oversupply is reduced, natural gas prices begin to rise gradually. Increased oil targeted drilling will contribute additional gas to overall supply as oil production also brings on associated and solution gas, but total gas deliverability will still be less than in 2011. Liquids-rich natural gas drilling will take place in locations where NGL contents are high enough to make production economic.
In the Mid-Range Price Case, Canadian natural gas deliverability will continue to be well above Canadian demand. The rate of decline in overall deliverability slows slightly due to higher productivity wells coming on-stream. Tight gas and shale gas activity stabilizes in 2012 with 229 wells drilled in the Montney and 39 in Horn River. Horn River deliverability decreases from 16 106m³/d (555 MMcf/d) in 2012 to 15 106m³/d (522 MMcf/d) in 2014. Montney deliverability increases from 46 106m³/d (1.62 Bcf/d) in 2012 to 55 106m³/d (1.95 Bcf/d) in 2014.
Slowing gas drilling activity and rising natural gas demand would begin to reduce the oversupply conditions. Reduced drilling for dry natural gas is expected to occur in Canada and the U.S. Growth in Canadian natural gas demand would consume a greater proportion of the country’s available deliverability, thereby reducing the net volumes available for export. Prices rise by U.S. $0.50 per MMBtu between 2011 and 2014.

The Higher Price Case would see a closer balance between supply and demand before the end of the projection period. As natural gas prices rise, a movement back towards dry natural gas targeted drilling takes place, starting with liquids-rich gas in 2012 and 2013 followed by growth in dry natural gas targeted drilling in 2014. As natural gas prices rise, there may be less substitution of coal-fired electricity generation by natural gas.
Canadian natural gas deliverability declines more slowly than in the Mid-Range Price Case due to additional natural gas-intent drilling. Deliverability decreases from 414 106m³/d (14.6 Bcf/d) in 2011 to 385 106m³/d (13.6 Bcf/d) by 2014. Liquids-rich natural gas is still the primary source of new production, along with growing volumes of associated and solution gas. Even with a greater increase in price when compared to the Mid-Range Price Case, dry natural gas drilling will not be significant until 2014 when prices reach U.S. $6.00/MMBtu and shallower, less complex dry gas developments begins to attract some capital. Horn River deliverability increases from 17 106m³/d (597 MMcf/d) in 2012 to 18 106m³/d (617 MMcf/d) in 2014. Montney deliverability increases from 47 106m³/d (1.67 Bcf/d) in 2012 to 61 106m³/d (2.16 Bcf/d) in 2014.
In the Higher Price Case, the return of dry gas activity during a period of high oil activity would put additional pressure on the drilling and pressure pumping services in particular. Cost escalation could accelerate if shortages of labour, equipment, or materials were to become severe. When combined with ongoing increases in solution gas, associated gas, and NGL-rich gas production, additional natural gas drilling will slow the decline in overall deliverability. Overall growth in deliverability will not take place over the projection period, even though natural gas prices rise each year.

Full results of this case are available in Appendix C.
The Lower Price Case assumes a continuation of oversupply conditions due to significant contributions from solution gas, associated gas, and more U.S. NGL-rich gas. The Lower Price Case sees substantially less natural gas drilling activity than in the Mid-Range Price Case since most drilling in the Lower Price Case is supported solely by oil and NGL prices. Lower natural gas prices would impact drilling in areas with lesser NGL content as they would slip below the economic cut-off. The minimal dry gas drilling in the Mid-Range Price Case would be further discouraged.
Canadian natural gas deliverability declines steadily to 341 106m³/d (12.0 Bcf/d) in 2014, a decrease of 73 106m³/d (2.6 Bcf/d) from 2011, but is still well above Canadian demand. Lower natural gas prices would further reduce the attractiveness of investment in the sector.
Canadian natural gas consumers would benefit from lower natural gas prices. However, this case also shows the greatest decline in natural gas deliverability. Oil-related activity might be able to compensate for reduced natural gas operations to maintain Canadian drilling and service activity. The potential transition toward oil and away from natural gas would tend to shift some capital investment away from gas-prone B.C. and into oil-prone Saskatchewan, while the impact would be mixed in Alberta.

The Board’s outlooks for gas deliverability and Canadian gas demand over the projection period are included in Table 4.5. The Board projects annual Canadian natural gas demand to grow by 17 106m³/d (0.6 Bcf/d) between 2012 and 2014. Most of this increase in natural gas demand would be from increased usage for oil sands development in Alberta. Natural gas deliverability, even in the Lower Price Case, will exceed expected Canadian demand.

Comparing the actual performance in deliverability with the Board’s most recent assessment, Short-term Canadian Natural Gas Deliverability 2011-2013, Canadian natural gas prices in 2011 tracked very close to the Board’s Mid-Range Price Case, however, deliverability was higher than forecast and was above the Board’s High Price Case.[8] This likely occurred for a few key reasons:
