The Knox plant will increase Oneok’s Oklahoma gas processing capacity to 900 MMcfd. It and the related infrastructure, including expansions and upgrades to the company’s existing gas gathering and compression, are to be completed during fourth-quarter 2016.
The estimated costs include $175-240 million to build the plant and $190-230 million to build related systems, including gas gathering pipelines and compression.
Oneok said it plans total investments of $6.4-6.8 billion through 2016 for acquisitions and infrastructure growth projects related to gas gathering and processing and NGLs, including the Knox plant and gathering.
The investments consist of $3.4-3.7 billion for gathering and processing and $3-3.1 billion for NGL. Some $3.1-3.3 billion are for projects related to development in the Williston basin in North Dakota.
