Conventional Oil and Gas Gains Competitive Edge

The surge in tight oil production from the U.S. over the last few years has forced companies in conventional plays to optimize operations to compete with the relatively low-cost barrels being pumped from Lower 48 shale plays.

Consultancy Wood Mackenzie indicates that while the price crash was painful for conventional producers, they have made gains: many conventional pre-Final Investment Decision (FID) projects are now competitive with Lower 48 breakevens.

Harry Paton, Senior Analyst, Global Oil Supply, said: “Costs have come down significantly since 2015. And the number of deepwater FIDs taken at the end of 2017 indicates a mood of quiet optimism in the upstream sector.

“Some conventional projects already compete with U.S. tight oil. World-class discoveries in Brazil and Guyana, for example, which have giant reserves and high-quality reservoirs, have project breakevens lower even than most tight-oil plays. In other, more mature sectors, such as the U.S. Gulf of Mexico or the North Sea, operators have made great progress in bringing costs down.”

However, this new competitiveness has come at the expense of volumes, he says. “Production from conventional pre-FID projects today will be considerably lower than Wood Mackenzie’s pre-price crash forecasts. The key driver is the large number of projects which have fallen completely out of the picture because they are uneconomic and have been delayed or canceled. Many projects now in the mix have been changed in scope. Operator mentality has shifted to ‘value over volume.’ This brings significant cost savings, but takes a chunk out of production for many assets.”

This raises two key issues: rising cost of supply and a potential supply gap, caused by both declining legacy field production and a projected growth in demand. Wood Mackenzie believes the cost of supply is set to increase, as future production will be sustained by higher-cost (greater than $60/bbl), non-OPEC sources. Low-cost OPEC capacity growth will not be able to meet the gap created by declines in higher-cost, non-OPEC volumes. This higher-cost production is set to increase from 1.7 million b/d in 2017 to 5.3 million b/d in 2027. By 2035, these volumes should reach 9.2 million b/d.

Paton said: “Wood Mackenzie calculates that non-OPEC conventional onstream declines stabilized at around five percent in 2016. Our analysis suggests they will stay at this level through to 2020 before increasing to historic norms of six percent per annum.

“Combine this with demand growth of around eight million b/d and the resultant supply gap is around 23 million b/d in 2027.”

Key to filling this gap are volumes produced via U.S. Lower 48 future drilling and pre-FID projects. These are the future marginal cost barrels which will play an important role in setting the price over the next decade. The Lower 48, in particular, will emerge as an important marginal barrel producer.

“When you look at the numbers in terms of total production, our research suggests the U.S. Lower 48 will be one of the most expensive sources of supply in 2027,” Paton said. “The cost of tight oil will rise as higher-cost new drilling is required to offset declines as core, sweet-spot acreage is drilled out. This contrasts with conventional resource themes which benefit from longer-life assets providing a relatively cheap, stable base of production.”
