Abstract

fetched live from OpenAlex

Abstract Exploration in the 1970s and early 1980s identified approximately 4.2 TCF of natural gas and 123 million barrels of natural gas liquids on the Labrador Shelf within the Hopedale and Saglek basins. At the time, development was deemed unfeasible due to insufficient reserves and the threat posed by icebergs. Subsequent work has shown the original iceberg risk analysis to be very conservative. An iceberg risk model was developed to update the previous analysis and additional data was collected through a series of field programs. This resulted in a large multibeam mosaic covering the Makkovik Bank and pipeline landfall at Cape Harrison, and the development of a large iceberg scour database. An alternate landfall has also been identified at Cartwright with lower iceberg risk than the originally selected site. In 2010, the Oil and Gas Corporation of Newfoundland and Labrador (OilCo) undertook a regional oil seep mapping and interpretation study covering all offshore Newfoundland and Labrador, to help identify areas of interest with active petroleum systems. Based on these results, from 2011 to 2020 Oilco acquired 2D and 3D long offset broadband seismic datasets targeting the Chidley Basin, in the slope and deepwater off Labrador. This data has been used to map and quantify potential hydrocarbon systems within the basin. In 2021, Beicip-Franlab conducted a resource assessment on behalf of OilCo, based on available geological and geophysical data from the Chidley Basin. As reported in "Offshore Newfoundland & Labrador Resource Assessment, Labrador South NL-CFB03", "results show the very likely occurrence of a working petroleum system in the Chidley Basin capable of efficiently generating and preserving liquid and gas hydrocarbons in the slope and deepwater basin". Hence, the probability of additional resources to increase the total reserves available to support a gas development is considered high. If exploration drilling confirms the presence of gas, then the total gas available for development will include the original 4.2 TCF and any new reserves. Hence, the two barriers originally identified to the development of Labrador gas (iceberg risk and gas reserves) may be resolved.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
