Project Profile
Value: US$120 million
Location: Connect Piceance Basin in northwestern Colorado with Overland Pass Pipeline
Capacity: 100,000 barrels per day of raw natural gas liquids
Length: 150-mile
Start-up Year: November 2009
Overland Pass Pipeline Company, LLC, a joint venture of ONEOK Partners, L.P and Williams, built in 2009 a US$120 million natural gas liquids pipeline lateral connecting the growing Piceance Basin in northwestern Colorado with the Overland Pass Pipeline. The 150-mile lateral pipeline is designed to transport as much as 100,000 barrels per day of raw natural gas liquids from the Piceance Basin to the 750-mile Overland Pass Pipeline.
The pipeline lateral will transport natural gas liquids from an existing Williams natural gas processing plant and a new processing plant in the Piceance Basin. Under long-term natural gas liquids transportation and fractionation agreements that have been finalised, Williams dedicated its natural gas liquids production from an existing plant and its newly announced Willow Creek, Colo., natural gas processing plant to the Overland Pass Pipeline via the proposed 150-mile pipeline extension.
Construction on the 14-inch lateral pipeline to the Piceance Basin begun in the summer of 2008 and operation commenced in 2009. The pipeline lateral was designed, constructed and operated using proven technology, advanced pipeline control systems and continuous safety monitoring. ONEOK Partners will initially owned 99 percent of the joint venture and Williams will own the remaining 1 percent, with Williams having the option to increase its ownership to 50 percent and become operator within two years of the original Overland Pass Pipeline becoming operational. Williams used this right in November 2011 and became the operator of the pipeline with 50% interest.
Operators:
Williams: Operator with 50% working interest
ONEOK Partners, L.P: 50% interest
