Thank you.
Pipelines are designed based on the properties of the natural gas they transport. In other words, a different type of pipeline will be required, or a different type of pipeline design will be required, if the pipeline has liquids associated with the natural gas or if it has sour gas constituents such as carbon dioxide or hydrogen sulfide within the natural gas. Those are the things that really determine whether a pipeline can be used to transport gas from a different supplier.
It's not necessarily a distinction between unconventional gas and conventional gas, because we certainly have examples of conventional gas that is as relatively sweet and free of carbon dioxide and hydrogen sulfide as an unconventional play. We have other examples in which conventional and unconventional plays have very different raw gas composition characteristics. There's nothing one can really generalize about the gas compositions from conventional and unconventional plays.
