'Spring' Testing Window3 Feb 2026 10:23
There’s been a lot of confusion, speculation, and contradictory timelines floating around, so this thread sets out a clear, factual summary of what the most probable Dubhe‑1 testing window looks like based on North Slope operating rules, weather constraints, and Pantheon’s own statements.
Dubhe‑1 sits on a gravel pad, but the short distance between the Dalton Highway and the pad is natural tundra rather than a gravel road. On the North Slope, tundra only supports heavy equipment when frozen and snow‑covered, becomes impassable during thaw, and is regulated by Alaska DNR. This creates a fixed annual window for heavy operations and is why “winter” is the key operating period for exploration wells across the region.
Given we are now in early February, the most probable operational window for mobilisation, testing, and demobilisation is late February through early April. Outside this frozen‑tundra window, operators cannot move heavy equipment, cannot bring in or remove test packages, and cannot run a full flow test that requires mobilisation and demobilisation. This is why testing in May/June is not realistic despite some suggestions to the contrary.
It’s also important to understand that “spring” for Alaska oilfield operations does not mean May/June. In industry terms, “spring” refers to the late‑winter period when the tundra is still frozen but the worst of deep‑winter weather has passed and daylight is rapidly increasing. This period typically falls into late February – early April. All operations and demobilisation must be completed before the tundra thaws, because once it does, the access route between the Dalton Highway and the pad becomes impassable to heavy equipment.
The well is currently shut in to gather pressure‑build‑up data, including reservoir pressure response, skin/damage indicators, permeability behaviour, boundary effects, and modelling inputs for restart. This is a normal and planned part of multi‑phase testing and does not imply any problem.
Pantheon stated in the mid‑January RNS that they would update the market in the “coming weeks.” Given the likely operational window, the re‑entry/testing‑plan RNS would logically need to land before mobilisation, making early–mid February the most probable period for that update, with mobilisation shortly after.
