Shale Gas and the Relationship between the U.S. Natural Gas, Liquefied Petroleum Gases and Oil Markets / Atle Oglend, Morten E. Lindbäck and Petter Osmundsen. University of Stavanger, July 2013, 30 p. (USAEE Working Paper No. 13-135)http://papers.ssrn.com/sol3/papers.cfm?abstract_id=2295604Authors's abstract :Natural gas liquids and liquefied petroleum gases have played an important role in the current US shale gas boom. Depressed gas prices in recent years have made pure natural gas operations less profitable. The result is that liquids components in gas production have become increasingly important in ensuring the profitability of shale gas operations. In this paper we investigate whether the shale gas expansion, which has led to an increase in associated LPG production, has also affected the historically strong relationship between LPG and oil prices. Revealing the strength and stability of the LPG/oil relationship is relevant when it comes to the future profitability and development of the U.S. natural gas sector. Our results suggest that the LPG/oil relationship has weakened in recent years with a move towards cheaper liquids relative to oil. This is consistent with developments in the gas sector with increased liquids production. A consequence is that U.S. natural gas operations cannot automatically rely on high liquids prices to ensure profitability.
