Conventional Natural Gas Supply Costs in 1 Western Canada – An Update
December 2013
Introduction The abundance of shale gas developments in the United States has led to sustained low natural gas prices across North America, making the majority of Canada’s dry gas resources uneconomic to develop.
1 The exception is those resources that contain significant amounts of
natural gas liquids (NGLs).
This report updates CERI Study No. 136, Conventional Natural Gas Supply Costs in Western Canada released in June 2013 to include the supply cost of producing gas on a liquids-basis (that is, including the revenues and costs for both dry gas and NGLs) for numerous areas across Western Canada. Previously, the study only looked at supply costs on a dry-gas basis, effectively ignoring the liquids component.
Produced natural gas is primarily methane (CH4), but it also contains heavier hydrocarbons that are separated from the natural gas stream as liquids, including ethane (C2H6), propane (C3H8), butane (C4H10) and pentanes plus (C5H12 and greater). With the price of NGLs generally linked to oil prices instead of natural gas prices, the presence of liquids in the gas stream improves the potential returns from developing these types of resources. The higher the spread between natural gas prices and oil prices, the higher the incentive to extract the liquids.
The supply cost calculation provides an indicator of the economic viability of producing gas in each of the study areas. With the inclusion of NGLs in the analysis, this update presents a more realistic evaluation of the economic viability of natural gas production in liquids-rich areas across Western Canada.
Results The supply cost represents the natural gas price that is required to recover all costs (capital, operating, royalties and taxes) and earn a positive return on investment (10 percent real). Simply put, if the supply cost is lower than the current natural gas price, that area is considered economically viable to develop. (Note that the supply cost calculation assumes a price for NGLs, it does not solve for the price of NGLs.)

The presence of liquids improves the economics of gas extraction. The analysis shows that the dry-gas portion of the supply cost can decline significantly in the presence of liquids. In some cases, the dry-gas costs are almost completely offset by revenues from the liquids.
Given the favourable economics for liquids-rich gas, there has been a substantial shift in drilling towards exploiting these resources across Western Canada. The share of new connections in southeast Alberta, a typically dry-gas region, dropped from 41 percent in 2011 to 20 percent in 2012, while the share in the foothills region of Alberta, a typically liquids-rich region, increased

from 39 percent in 2011 to 62 percent in 2012.3 The Montney formation in British Columbia has
also emerged as a key producing region over the past 5 years. These changes are primarily driven by the shift towards liquids-rich gas resources as producers take advantage of the additional revenue associated with the production of NGLs.
Figure 1 shows the number of wells completed in Alberta and British Columbia, by study area since 2010.
4 Total drilling rates have been declining since 2008, in line with the decline in
natural gas prices and the advent of horizontal drilling and multi-stage hydraulic fracturing. The shift to liquids-rich resources is also evident, as areas that had traditionally shown strong gas production, such as southeast Alberta (Area 1), have shown steep declines over the past three years. In the case of southeast Alberta, wells completed dropped from over 1,000 wells in 2010 to only 36 in 2012.

Those areas with the largest drilling and completion rates are those with a strong liquids-rich gas resource. Figure 2 shows the number of wells completed in 2012 and the average liquids content of those areas. Only a handful of areas in Western Canada had completion rates of above 100 wells in 2012, and those areas generally have an average liquid content of over 40 bbls of NGLs per mmcf of gas.

Conventional Natural Gas Supply Costs in 3 Western Canada – An Update
December 2013
Typically, liquid-rich plays in Alberta run from the northwest near Grand Prairie diagonally
southeast to the Medicine Hat area encompassing the Duvernay, Montney and Muskwa formations.
5 Liquid-rich plays in British Columbia are centered on the Montney formation in the
northeast of the province.

Table 1 shows the supply costs for all areas on a dry-gas basis (as in CERI Study No. 136) and on a liquids basis (updated to include NGLs). The new supply cost is then split into a gas portion and liquids portion. The liquids portion reflects the amount of the supply cost that is covered by revenues from liquids produced. The gas portion is then calculated as the gas price required to cover the remaining costs and earn a positive rate of return. It is the gas portion that should be compared to the current gas price to determine the economic viability of gas production.
The areas in bold represent those areas with a completion rate of more than 100 wells in 2012. It is evident that for these areas, the liquids revenue makes up a greater proportion of the total supply cost, resulting in a lower gas portion, and greater profitability.
Note that the addition of NGLs in the supply cost calculation causes the total supply cost for each area to increase from the dry-gas estimate. This is because additional operating and

transportation, fractionation, etc.). However, after accounting for the additional revenues gained from the liquids, the gas price required to cover the remainder of the costs falls (the gas portion).

The analysis shows that those areas that experienced significant drilling in 2012 are also areas that enjoy high liquids content, with most of those areas enjoying a liquids content of over 50 bbls/mmcf. While this pattern is generally true, there are also areas within Alberta and British
Columbia that show high liquids content but low drilling and completion activity. In these cases the production profile of both gas and liquids do not make the economics of extraction attractive.
The biggest uncertainty in analyzing NGLs is the price that producers receive for liquids. Two sensitivity analyses were undertaken to examine this uncertainty. Since prices for NGLs (C3+) are generally linked to the price of oil, a high and low oil price scenario was examined. In addition, given recent fluctuations in the price of propane, a high and low propane price scenario was also analyzed.
The results show that a high oil price brings about more favourable economics for liquids-rich
gas development as producers are receiving a higher price for their liquids. This leads to greater revenue from liquids, and therefore a lower gas price required to make the development economically viable. The opposite is true for low oil prices. In total, the supply cost for each area changes very little with the change in oil prices, however, it is the breakdown between the gas and liquids portion that is more important. Figure 3 shows the sensitivity analysis results for just one area, Area 13 in central western Alberta. The total supply cost under the high oil price case is $0.11 higher, with the liquids component increasing $0.29 and the gas component falling $0.18.
The propane sensitivity scenarios show the same relationship as the oil price scenarios, but to a lesser extent. Full sensitivity analysis results are presented in Appendix B.

Plays such as the Montney and Duvernay, along with other liquid-rich resources, are set to
remain the focus of development in the Canadian gas industry into the future. Given the outlook for sustained low natural gas prices, developers will continue to pursue those resources that produce the highest economic value-added. The expansion of the Canadian shale gas industry and the continued refinement of production processes will only result in better economics for these liquid-rich plays.
Appendix B presents detailed supply cost estimates for those areas with completion rate of 100 or more in 2012.
Methodology and Assumptions The overall supply cost method and assumptions are the same as those used in CERI Study No. 136. Only those that are different or new are outlined below.
Liquids content – Natural gas reserve and composition data was used to derive the average liquid content of each study area. These data were provided by the Alberta Energy Resources Conservation Board (ERCB) – now the Alberta Energy Regulator (AER) – and the British Columbia Oil and Gas Commission (BCOGC). The gas and liquid composition of each area is a weighted average based on the remaining producible volumes of natural gas.
Liquids recovery – Two liquid recovery scenarios were developed: Shallow cut and Deep cut. The Deep cut scenario has been used as the main scenario for this analysis.

Operating costs – CERI Study No. 136 presented supply cost estimates that were measured at the field gate, that is, it did not include the costs of transportation or processing. This report has
updated the supply cost estimates to include these costs for both the dry gas and liquids components.
NGL operating cost estimates include:
Processing and treating - estimated by CERI from various company data
NGL raw mix transportation – estimated by CERI from various company data
NGL fractionation – fractionation costs estimated from the Alberta Department of Energy fractionation allowance
While the same operating costs have been assumed for all areas, some areas may have higher or lower operating costs depending on their individual circumstances, and this would change
the results.
Transportation costs – Gas transport costs and NGL product transport costs were estimated by CERI from various company data
NGL prices – Unlike the natural gas price, which is a product of the supply cost calculation, NGL prices are exogenous to the model.
Ethane – Typically trades at gas value plus a premium. Ethane prices have been calculated as NOVA Inventory Transfer (NIT) purchase prices with uplift calculated by CERI.
Propane, butane and pentanes plus typically trade as a proportion of WTI, prices have been assumed as 30, 80 and 106 percent of WTI, respectively.
Sensitivity analysis – two sensitivity scenarios are presented in Appendix B:
Low/High Propane Price – the low propane price scenario assumes a propane price equivalent to 20 percent of WTI, while the high propane price scenario assumes a propane price of 40 percent of WTI.
8 Canadian Energy Research Institute
December 2013
Low/High Oil Price – the low oil price scenario assumes an oil price 15 percent lower
than the WTI, while the high oil price scenario assumes an oil price 15 percent higher than WTI.
Please refer to CERI Study No. 136 for all other assumptions.
