A review of Mackenzie Delta-Beaufort Sea petroleum province conventional and non-conventional (gas hydrate) petroleum reserves and undiscovered resources: a contribution to the resource assessment of the proposed Mackenzie Delta-Beaufort Sea Marine Protected area
Bibliographic record
Abstract
The Beaufort-Mackenzie Basin hosts an immense petroleum resource. Fifty-two petroleum fields found by 263 wells, including four gas hydrate research wells, have discovered petroleum expected to be 172.75 X 106m3 recoverable crude oil (RCO) and condensate and 254.67 X 109m3 marketable conventional natural gas (MNG). The region is estimated to have an expected undiscovered 957.2 X 106m3 RCO and 1.64 X 1012m3 recoverable conventional natural gas. The conventional resources are co-located with an immense gas hydrate resource estimated between 2.4 X 1012 and 87 X 1012m3 raw natural gas in place. Development of the, often co-located, gas hydrate petroleum resource could augment the conventional petroleum province significantly within the production life span of the conventional onshore fields. The undiscovered gas in the Kendall Island and Kugmallit Bay regions of the proposed Mackenzie Delta - Beaufort Sea Marine Protected Area (MPA) is a portion of 356.94 X 109m3 undiscovered gas, including possibly a gas field >28.33 X 109m3 MNG gas plus the discovered gas within its boundaries. The inference of the total gas potential in the proposed MPA is not possible because there is no assessment of undiscovered gas potential in the West Beaufort play group, and therefore there is no basis for inferring the conventional natural gas potential of the Mackenzie Bay region of the proposed MPA. The total undiscovered crude oil potential in the proposed MPA is some fraction of 466 X 106m3 recoverable crude oil that might include one undiscovered pool >16 X 106m3 and multiple undiscovered pools >4.0 X 106m3 in the Kendall Island and Kugmallit Bay regions and one to three crude oil pools >16 X 106m3 and some fraction of the 12 undiscovered pools in the 3.97 to 15.87 X 106m3 size range in the Mackenzie Bay region. Within the region of the MPA the total gas hydrate potential is estimated to be between 1.27 X 1010m3 - 4.60 X 1011m3 raw natural gas in place. The specific impact and effect of three candidate Marine Protected Area (MPA) sites identified by the Department of Fisheries and Oceans (DFO) in the southern Canadian Beaufort Sea on the exploration, development and transportation of existing regional petroleum reserves and resources cannot be appropriately determined using the available sources of data and inference. There is no consensus regarding either the discovered reserve or the undiscovered potential among various stakeholder groups, based on the pre-2002 data set alone. Since 2002 much important new, confidential industrial data has been acquired.

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.
