Western Canada’s Montney-sourced natural gas production has been on a remarkable upward trajectory in the past decade. Most of this growth has been focused in one province: British Columbia. However, that progress has not come without difficulty. A key challenge during BC’s gas boom has been providing sufficient pipeline takeaway capacity — the hurdles include the BC Montney’s remoteness, various regulatory impediments, and the unique geologic nature of the play. For this amazing gas supply growth story to continue well into the future, more pipeline capacity needs to be constructed. In our concluding blog on the Montney, we discuss recent pipeline developments and the challenges still ahead.

The Montney Formation in British Columbia and Alberta is exclusively responsible for the turnaround in Western Canada’s natural gas production in the past decade. Gas production in the Montney — a vast area with extraordinary reserves — has doubled in that time, with most of that growth coming from the BC side of the formation. This phenomenal growth story stems from a few key factors, including steadily improving gas well performance and increasing wellbore length, coupled with access to an established network of gas pipelines. Today, we delve into what has made BC’s portion of the Montney such as standout.

In just a few years, the Montney Formation has become the most prolific natural gas production region in Western Canada. Starting from zero in 2005, the Montney has been the primary growth engine for gas supplies and continues to challenge producers to deal with its vast geographic extent and enormous reserve potential. Spread across swaths of Canada’s two westernmost provinces, the formation’s unique geology has meant that its gas production growth has moved at different speeds depending on location, geology, and pipeline access. In this first part of a three-part series, we take a closer look at this important formation.

Last summer, Alberta natural gas prices staged a remarkable turnaround from the dismal lows and extreme volatility experienced the prior three summers. The price rise is widely credited to a temporary gas flow mechanism put in place by the operator of Alberta’s gas pipeline grid to combat congestion and oversupply issues associated with construction and maintenance during the summer of 2020. However, this temporary mechanism was just that — temporary — and will not be reinstated this summer. Without it, there is concern among Western Canadian gas producers that the weakness and volatility in gas prices seen during past summers might return this year. With warmer weather on the horizon, today we consider these issues and the potential for renewed price weakness in the Alberta natural gas market this year.

Natural gas production has been growing in Western Canada in recent years with an increasing share of that supply coming from core areas of activity within the Montney and Duvernay plays. This tighter focus has forced TC Energy to rework and expand its giant Nova Gas Transmission Limited pipeline system, a network that originally gathered gas supplies across a much larger geographic footprint. The problem is, it took far longer than expected for the latest round of NGTL expansions to win final approval from Canadian regulators. Today, we review the next phase of the pipeline’s system development, and what the regulatory delay might mean for Western Canada’s gas market.

Natural gas supplies in Western Canada fell into a hole in 2019, registering their first decline in a half-dozen years. That drop was led by a supply pullback on TC Energy’s Nova Gas Transmission Limited (NGTL) system, the largest gas pipeline network in the region, as producers grappled with widespread pipeline maintenance, shrinking budgets, and wellhead shut-ins due to ultra-low prices, especially during the summer months. That supply hole is going to be fixed in the months ahead, thanks to a major pipeline expansion — the North Montney Mainline — that recently entered service with a direct connection into the NGTL system. With this new pipeline tapping deeper into the vast Montney formation in northeastern British Columbia, gas supplies are showing signs of pushing higher, and more upside is expected in the months ahead. Today, we examine the new pipe and what it means for gas supplies on NGTL.

The Alberta natural gas market in Western Canada is in the midst of a seismic shift. Regional gas supply growth is accelerating. At the same time, export demand is eroding, but domestic demand — particularly from gas-fired power generation and oil-sands development — is on the rise. The incremental production along with the move toward intra-provincial demand has reconfigured flows and strained TransCanada’s infrastructure in the region. These factors resulted in extreme price volatility this past fall, a dynamic that’s likely to resurface in the New Year during low-demand times. Today, we continue our analysis of the Western Canadian gas market with a look at the changing transportation and flow dynamics in Alberta.

Western Canadian natural gas producers are increasingly facing oversupply conditions and price volatility. While competition and pushback from growing U.S. shale gas supply continues to be a factor, producers are now also contending with fresh problems closer to home — namely transportation constraints right where production is growing the most, in central Alberta. This fall, the Alberta market experienced extreme bottlenecks that left production stranded and sent area gas prices reeling. The ramp-up of winter heating demand has since helped ease the constraints, but the problems are likely to return in the spring when demand is lower, leaving producers exposed to the risk of severe price weakness again in 2018 and limited in their ability to grow supply. Today, we continue our look at what’s behind the local constraints and the implications for production growth and prices in Western Canada.
