Thanks, Paul. Good morning, everyone.
2016 was a successful year for Pembina Gas Services business as we added approximately 450 million cubic feet per day gross from new processing capacity. Expansions were completed at both our Resthaven and Musreau facilities early in the year. And in April, we closed the acquisition of the Kakwa River facility, which represents Pembina's first sour gas processing facility. Pembina continues to advance our infrastructure platform in the Duvernay. Engineering is 85% complete. All major equipment has been ordered, and site grading and piling activities are now finished for our 100 million day -- 100 million cubic feet per day Duvernay 1 facility. At the field hub, all required regulatory approvals have been received. Engineering is 55% complete, initial civil work is done. Both projects are expected to be brought into service in the fourth quarter of 2017, and the expected total investment is approximately $240 million.
We are very pleased to be -- to have been selected by Chevron Canada Limited to be their midstream service provider of choice to support their Duvernay development. As we recently announced, Pembina and Chevron have entered into a 20-year infrastructure development and service agreement. The agreement includes an area of dedication by Chevron in excess of 10 gross operated townships, over 230,000 acres, concentrated in the prolific, liquids-rich Kaybob region of the Duvernay resource play near Fox Creek. Under the agreement, and subject to Chevron sanctioning regional development, Pembina will construct, own and operate gas-gathering pipelines and processing facilities, liquid stabilization facilities and other supporting infrastructure. Additionally, Pembina will provide long-term service for Chevron on its pipelines and its fractionation facilities. In aggregate, and subject to internal Chevron and regulatory approvals, the infrastructure developed over the term of this agreement has the potential to represent multibillion dollar investment for Pembina. While this agreement and respective obligations are binding, the infrastructure fulfillment [ph] remains contingent upon Chevron's sanction as well as necessary environmental and regulatory approvals.
The development of our proposed PDH and PP facility is well underway. We've completed our detailed feasibility study, which yielded encouraging initial results. We are also encouraged by the conditional award of $300 million in royalty credits from the Alberta government's petrochemical diversification program late last year. We hope to make a decision about FEED by the end of the first quarter of 2017. Key deliverables of the FEED phase include regulatory application, a Class 3 cost assessment, a project execution plan, among other items. We are aiming to make a final investment decision of this project by the second quarter of 2018. Subject to regulatory, environmental and Pembina's board approval, the project could be in service by 2021. Overall construction of RFS III is at 90%, and the facility will be effectively complete by early in the second quarter of 2017, which will be followed by commissioning activities. We expect to be able to bring RFS III into service early in the third quarter of 2017, ahead of our original expectations. Pembina continues to progress construction on infrastructure in support of the North West Redwater Partnership planned refinery. Overall, the project is now 70% complete, engineering and procurement activities are over 90% finished, nearly all materials and equipment have arrived on site. Various phases of the project will be placed into service throughout 2017, and by year's end, the project will be complete.
