Hydrological dynamics following partial removal of an oil well pad undergoing restoration to a boreal peatland
Bibliographic record
Abstract
Many peatlands on the North American Western Boreal Plain have been disturbed by industry, including through the construction of thousands of oil well pads. The introduction of fen mosses onto residual mineral well pads following their partial removal has been proposed as a novel technique to restore these sites. However, it has remained unclear whether this would support the requisite hydrological conditions for fen moss establishment. To assess this, a field study of hydrological function at a partially removed pad undergoing restoration near Slave Lake, Alberta, Canada was undertaken. Specifically, the hydrophysical properties of the residual fill and adjacent peatland (including hydraulic conductivity, bulk density, and porosity) were characterized, and related to subsurface flow and water table regulation within the partially removed pad and adjacent peatland. The results demonstrate that flow through the peatland was disrupted by the low saturated hydraulic conductivity of the residual fill (1.15 × 10 −5 m s −1 ) and the compacted underlying peat (4.91 × 10 −6 m s −1 ), resulting in preferential flow around the pad. On the residual pad, hydrological connectivity with the adjacent peatland resulted in a well-regulated, near-surface water table across nearly half of its surface area. However, limitations on subsurface flow through the pad footprint resulted in variable hydrological dynamics across much of its interior. These findings suggest that partially removed well pads have the potential to support requisite hydrological conditions for fen moss establishment, but further development of the technique should be undertaken to improve subsurface hydrological connectivity with adjacent peatlands. • Residual pads have significantly different hydrophysical properties than peatlands. • The low hydraulic conductivity of a residual pad impeded flow through a peatland. • Preferential flow around a well pad remained evident following partial removal. • Partial well pad removal creates variable hydrological conditions for moss survival. • Modification of the technique may improve hydrological connectivity and regulation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
