$UWTI - According to data compiled by FactSet, aggregate net debt for U.S. oil and gas production companies increased from $81 billion at the end of 2010 to $169 billion by June 2015.

This debt will become increasingly more difficult to service over the next couple of years with interest rates rising and also, U.S. shale producers reported a deficit in cash flow of over $37 billion in 2014.
