As part of the deal, William Partners will acquire oil sands offgas processing plant near Fort McMurray, around 260 miles of NGL and olefins pipelines, as well as NGL or olefins fractionation facility and butylenes or butane splitter facility at Redwater.

In addition, the acquisition includes an in-progress expansion project at the Redwater facility.

The expansion is expected to provide additional fractionation business to Williams Partners related to development of offgas processing at the CNRL Horizon upgrader facility retained by Williams.

Williams Partners is engaged in natural gas transportation, gathering, treating, and processing, storage, natural gas liquid (NGL) fractionation and oil transportation.

Williams operates around 15,000 miles of interstate gas pipelines, 1,000 miles of NGL transportation pipelines and about 10,000 miles of oil and gas gathering pipelines.
