Developing Countries Lead Demand For New Energy Sources

John England, Vice Chairman, Deloitte

Global demand for energy continues to grow, especially in developing countries such as China and India, as the oil and gas industry continues to search for new sources of energy. Increasingly, oil and gas are found in challenging areas, such as deep water, arctic regions and politically challenged regions of the world.

For the past five years, however, the headline for the industry has been the dramatic development of unconventional oil and gas in the U.S., such as shale gas and tight oil. Unlocked by technological advancements, development of these resources continues to change the global landscape of oil and gas.

Impact Of The Shale Revolution

As a result of the “shale revolution” in the U.S., domestic dry gas production increased 25% from 2007 to 2012. According to the U.S. Energy Information Administration (EIA), domestic production of dry natural gas reached an all-time high of over 65 Bcf/d in July 2012. Natural gas volumes continue to swell U.S. storage capacity with working natural gas in storage at 88 % of total capacity.[1] One important result of the surge in natural gas production is the natural gas price has become uncoupled from the oil price in the U.S. while natural gas is still priced off of crude oil in the rest of the world. In April 2012, as oil prices surged and natural gas prices plummeted, the U.S. oil-to-gas price ratio rose to a high of 53 in absolute terms and over nine in energy-equivalent terms.

However, the supply of dry gas on the market is expected to continue to grow even under a weak natural gas price scenario. This is due to the fact that dry gas is produced as a by-product of development from still profitable liquids-rich shale plays. According to the EIA, an average wet shale play in the U.S. with 35% liquids content produces around 11,000 cubic feet of dry gas per barrel of natural gas liquid produced. During 2007-12, Baker Hughes reported that the horizontal rig count, the type of rig predominantly used in shale gas plays, tripled while the natural gas rig count fell to a 13-year low. U.S. dry gas production and horizontal rig count data for the past five years show a correlation of 92%.[2] As a result, associated gas from liquids-rich shale plays is expected to triple from 2006 levels by 2020.[3]

To maintain profitability, oil and gas companies have turned from dry gas production, which is largely uneconomic at current prices, to the production of the liquids portion of shale gas formations. Here too, shale gas is again revolutionizing the market. BENTEK has forecast that natural gas liquids production will increase by 500,000 barrels per day to 3.1 MMbpd in 2020, of which 50% will be ethane. As a result of increasing liquids production, natural gas liquids products (ethane and propane) are themselves becoming uncoupled from the oil price. In July 2012, ethane sold for 30 cents per gallon, a 60% decline from the prior year.[4] The propane market is also experiencing price declines with prices falling 20% from April to May 2012.[5] At the Conway, KS hub the ethane-propane mix registered a near 30-year low at just 2 cents per gallon.[6]

The surge in liquids production is the result of continued innovation in the industry as it perfects the art of extracting the most resources from each shale formation. Technological innovations such as longer laterals, multi-well pads and multi-stage fracturing have reduced the full-cycle cost of shale gas wells by 40-50% compared to conventional wells, and more than doubled their average initial production rates to 60 MMcfd.[7] The entry of research and development-focused super majors and increased capabilities of service companies will continue to lower operating costs and increase well productivity. In 2008, a well in the Fayetteville shale was estimated to produce 1.8 Bcf of natural gas over its 30-year life. However, improvements in drilling technologies have increased that estimate to 3.2 Bcf per well.[8]

The market should prepare for produced volumes to rise even higher. The majority of the 19 recognized basins are still in early exploratory or development stages. Moreover, production is still ramping up in Marcellus, the largest U.S. shale gas basin. In July 2012, EIA data showed that Marcellus production exceeded Haynesville and reached 7.4 Bcf/d (compared to less than 3 Bcf/d in 2011).

The growth in midstream pipeline and processing infrastructure has not kept pace with shale gas growth, which has led to stranded gas supplies or increased flaring of natural gas. In 2011, approximately 35% of North Dakota’s natural gas production was flared or otherwise not marketed due to insufficient infrastructure.[9] The Interstate Natural Gas Association of America (INGAA) projects that a total of $200 billion in midstream investments will be required to accommodate the development of U.S. natural gas resources from 2012 to 2035.

As a result, ethane rejection (where ethane is sold as part of the natural gas stream rather than as a liquid) is increasing in regions such as the Marcellus Shale. Some companies in the Marcellus region are rejecting well over half their ethane production.[10] Other producers are burning ethane onsite in the absence of takeaway capacity or using it for compression or production.

It is clear that U.S. natural gas supply growth is outpacing demand growth, resulting in decade-low prices and peak inventory levels. EIA data shows that since 2007, total supply increased by 25% while demand rose by only 5%. U.S. natural gas prices plunged below $2 per MMbtu in April, and inventories reached 3.2 Tcf in early August, 12.5% higher than the five-year average. Even crude oil production in the U.S. is at a 15-year high of more than 6.5 MMbbl/d, according to EIA.

Export Potential

An increasing solution to burgeoning domestic production of both natural gas and crude oil as well as lagging domestic natural gas and petroleum products demand is to export. Oil and gas companies have applied for new liquefied natural gas export licenses with the U.S. government in order to profit from the price disparity between the U.S. domestic natural gas price and the foreign natural gas price, which is over $15 per MMBtu in Asia. Even factoring in an upper limit of $3 per MMBtu for liquefaction as well as estimated shipping costs of $1.50 per MMBtu to Europe and $3.75 per MMBtu to Asia, U.S. natural gas producers can still reap substantial profits from these transactions.[11]

The government is considering permit applications that total 20 Bcf/d, which if approved, would make the U.S. the largest natural gas exporter in the world when just five years ago, the country was preparing to become the world’s largest natural gas importer. The impact of U.S. exports on global natural gas markets is not yet known.

The export potential for oil and gas companies does not end there. According to EIA data, while domestic petroleum products demand fell 20%, U.S. refinery output remained flat, averaging less than 15 MMbbl/d during 2006-12 as U.S. refiners discovered profitable export markets for surplus production. From 2006 to 2012, U.S. exports of petroleum products have tripled 1-3 MMbbl/d with Latin America being the largest and the fastest growing export market for U.S. refiners driven by strong distillate demand in Mexico, Brazil and Chile.

Low-priced natural gas from shale is helping to fuel the growth in petroleum products exports. Gulf Coast refiners benefit both from lower U.S. natural gas prices and a higher percentage of natural gas in the feedstock. Gulf Coast refiners’ gas-related feedstock cost fell by nearly 60% since 2008 due to the steep fall in U.S. natural gas prices. During the same period, the equivalent feedstock cost for a European refiner increased 12% due to higher natural gas prices in the region and continued use of oil-linked feedstock for process fuel. The decline in gas prices since 2008 has doubled the feedstock advantage of Gulf Coast refiners over European refiners from around $1.25 a barrel to $2.45 per barrel.[12]
