•Long-term Agreement Expected to Add Nearly 15,000 Barrels Per Day of NGL/Olefins Production
•Project Builds on Company’s Growing Scale, Expertise in Canada’s Oil Sands Gas Processing
•New Operations to Further Reduce Upgrader Emissions
•Expect Project Funding from Canadian Cash Flows, International Cash On-hand
Williams (WMB) announced today that the company has signed a new long-term gas processing agreement with a producer in the Canadian oil sands.
Under the new long-term agreement, Williams will extract, transport, fractionate, own and market the natural gas liquids (NGLs) and olefins recovered from the offgas at the oil sands producer’s upgrader near Fort McMurray, Alberta. Under the agreement, the NGL/olefins recovered are expected to be approximately 12,000 barrels per day (bpd) by mid-2015 and growing to approximately 15,000 bpd by 2018.
The NGL/olefins mixture will be fractionated at Williams’ Redwater facilities into an ethane/ethylene mix, propane, polymer grade propylene, normal butane, an alkylation feed and condensate. The ethane price risk associated with this deal is mitigated via the previously announced long-term agreement to supply NOVA Chemicals Corporation with up to 17,000 bpd of ethane and ethylene.
The propane recovered will be sold into the local propane market and would potentially be used as feedstock at Williams’ proposed propane dehydrogenation (PDH) facility in Canada. The other products will be sold into the established markets where Williams sells existing NGLs and olefins produced in Canada.
“This new agreement will build on the unique expertise and large-scale infrastructure we’ve built in Canada,” said David Chappell, president of Williams Energy Canada. “The scale that we are building here – with fractionation, distribution and storage – gives us the ability to generate significant long-term incremental value from our operations.
“The new operations will also further reduce greenhouse gas and sulphur dioxide emissions from the upgraders’ oil sands operations, and produce valuable commodities that were previously being burned,” Chappell said.
The offgas processing that Williams pioneered significantly reduces emissions at its customers’ oil sands production facilities. Williams captures and processes a rich NGL/olefins mixture that would normally be burned by the oil sands producer. The producer instead burns methane that Williams provides in exchange for the NGL/olefins mixture.
Once full operating capacity is achieved at the producer’s location, processing the offgas is expected to reduce emissions of carbon dioxide (CO2) – a greenhouse gas – by an average of approximately 200,000 tonnes per year. It is expected to reduce emissions of sulphur dioxide (SO2) – a contributor to acid rain – by an average of approximately 2,000 tonnes per year.
When combined with Williams’ existing offgas processing at another third-party oil sands producer, the company’s operations in Canada will eventually reduce annual CO2 emissions by more than 500,000 tonnes and annual SO2 emissions by 4,500 tonnes.
New Facilities and Capital Expenditure Guidance
To support the new agreement, Williams plans to build a new liquids extraction plant and supporting facilities at the oil sands producer’s upgrader. It also plans to build an extension of its Boreal Pipeline that will enable transportation of the NGL/olefins mixture to its expanded Redwater facility outside of Edmonton.
The total capital expenditures expected for the project is CA$500 million to CA$600 million. The 2012-14 portions of the capital expenditures are included in Williams’ latest capital expenditure guidance, which was issued on Aug. 1.
Williams expects to fund the construction using cash flows from its Canadian operations as well as with international cash on-hand.
