What Happened in Wyoming - Crude Differentials Tighten at Guernsey as Demand Rises, Production Ebbs

Author John Zanner

In the U.S., crude oil trading hubs like Houston, Midland and Cushing get the lion’s share of the market’s attention. But travel a bit further north and you can find one of the more unusual and liquid crude markets in the country — Guernsey, WY — a focal point for producers in Western Canada, North Dakota, Wyoming, Utah and Colorado. Over the last few months, Guernsey differentials have tightened significantly, finally flipping to a premium to Cushing. We have seen this phenomenon occur before, most notably seven years ago after the startup of the Dakota Access Pipeline (DAPL). In today’s RBN blog, we discuss the recent movement in Guernsey differentials and what the future could hold for the often-overlooked sales point.

Pictures of You - Regional Balances Tell the Tale of the U.S. Crude Oil Market

Over the past 15 years, the U.S.’s crude oil supply/demand balance has been transformed by the Shale Revolution. Increasing production unlocked through horizontal drilling and hydraulic fracturing have pushed up the nation’s overall supply without an equal change in refining capacity, resulting in significant changes in regional balances. In today’s RBN blog, we discuss what PADD-by-PADD crude oil supply/demand balances can tell us and preview our latest Drill Down Report.

Basket Case - The Strange Relationship Between Mont Belvieu and Conway NGLs

Mont Belvieu, TX and Conway, KS, are the two most significant U.S. hubs for NGL trading, storage and fractionation, with the much bigger Mont Belvieu hub primarily serving Gulf Coast and export demand, while the smaller Conway hub is focused on Midwest/Great Plains demand, especially for propane. The pricing dynamics between the two hubs are a key indicator of the supply/demand balance between the regions, but they don’t have the same kind of influence over the direction or magnitude of flows as price differential dynamics often do for other energy commodities. In today’s RBN blog, we will examine the gap between the price of the NGL “basket” in Mont Belvieu versus Conway and what that price spread tells us.

Ruby, Ruby, When Will You Be Mine - Tallgrass Bid Breathes New Purpose into Languishing Ruby Pipeline

Tallgrass Energy last month snagged an early Christmas present: It won a bid for Ruby Pipeline, the beleaguered Rockies-to-West Coast natural gas system that has long been underutilized and cash-poor. In doing so, it beat out one of the largest midstream companies in North America and a long-time co-owner of Ruby — Kinder Morgan. Ruby may be a languishing asset, but for Tallgrass it’s more like a crown jewel in its quest to be the only transcontinental header system in the country that would connect trapped Appalachian gas supply with premium West Coast markets. Tallgrass’s Rockies Express (REX) pipeline is already moving Marcellus/Utica molecules west to the Rockies — the opposite direction than it was originally built for in the pre-Shale Era. The Ruby acquisition, which has yet to close, would allow Tallgrass to extend its reach farther west, directly into the premium West Coast markets. The Ruby deal comes at a time when California’s aggressive decarbonization goals are leading to gas shortages and exorbitant fuel premiums out west, and there’s an immediate need to debottleneck routes to get gas there. In today’s RBN blog, we begin a series delving into how Ruby fits into the Western U.S. gas market and what the acquisition would mean for Tallgrass.

Wild, Wild West - Natural Gas Price Blowouts Signal Worsening Westbound Supply Constraints

Last week, even as natural gas day-ahead prices went negative in the Permian’s Waha Hub in West Texas, spot prices at northern California’s PG&E Citygate last week traded at a record-smashing $55/MMBtu, according to the NGI Daily Gas Price Index — close to 100x the Waha price. Other hubs west of the Continental Divide also surged to record levels, while markets just east and north of there were largely unruffled — a sure sign of bottlenecks for moving gas into West Coast markets. This is just the latest instance of severe gas supply shortages and constraint-driven price disruptions out West in recent years (even ignoring Winter Storm Uri and the Deep Freeze of February 2021). Moreover, it’s arguably taking progressively more benign market events to trigger similar or worse shortages. What’s going on? In today’s RBN blog, we break down the factors driving the latest Western U.S. gas price spikes.
