ONEOK Partners LP said it will spend $180 million to $240 million by the first half of 2012 for natural gas liquids (NGL) projects in the Cana-Woodford Shale and Granite Wash plays.

When completed, the projects are expected to add 75,000 to 80,000 b/d of raw, unfractionated NGLs to the partnership’s existing NGL gathering systems in the Midcontinent and the Arbuckle Pipeline.

“These projects increase our ability to transport raw NGLs from these two important supply areas and better meet the needs of our customers,” said ONEOK COO Terry K. Spencer. “Our Arbuckle Pipeline plays an integral role in our ability to deliver NGLs to the Mont Belvieu, TX, market center.”

The projects include:

The projects are expected to be completed during the first half of 2012. The additional raw NGLs will be fractionated at either the partnership’s fractionation facilities or by third parties, ONEOK said.
