Oneok Partners LP has completed three projects that are part of an ongoing growth program worth roughly $5 billion. The partnership’s Bakken NGL Pipeline, Stateline II gas processing facility and new ethane header pipeline have all entered service, the partnership said Tuesday.

The Bakken NGL Pipeline transports unfractionated natural gas liquids (NGL) from the Bakken Shale and Three Forks formations in the Williston Basin to the partnership’s 50%-owned Overland Pass Pipeline, a 760-mile NGL pipeline from southern Wyoming to Conway, KS. The 600-mile pipeline has capacity to transport 60,000 b/d.

Stateline II is in western Williams County, ND, and has capacity of 100 MMcf/d. It is the third gas processing facility that Oneok Partners has completed in the Williston Basin since late 2011, joining the Garden Creek and Stateline I plants.

“The completion of Stateline II, along with our other two plants and associated infrastructure that are operational, will reduce the flaring of natural gas in the region, enabling producers to deliver natural gas to customers and improve the environment,” said Oneok Partners President Terry K. Spencer.

“This header pipeline will allow us to meet the growing needs of our petrochemical customers in the area by providing them with direct access to purity ethane supply,” Spencer said. “It also will improve our operational flexibility and reliability, while providing increased fee-based revenues to the partnership.”

The partnership said it has a $2 billion-plus backlog of unannounced growth projects that it continues to evaluate. It said last year it would spend between $980 million and $1.1 billion by 2014 on a slate of gas and midstream projects in Texas, Oklahoma and North Dakota (see Shale Daily, July 27, 2012).
