These regions are / were defined based on the areas defined in regional oil and gas maps from 2014 (post-devolution) onwards. The separation / clustering of the existing oil and gas licences made it somewhat debulous in terms of defining specific regions, as it was easy to use the selection box tool in ArcMap to simply select the licences that were to be aggregated for reporting roll-ups in the oil and gas annual report. However, a new system requires a consist geographically based selection layer, with defined regions, which resulted in this product being created. The mineal and petroleum geomatics officer in the Inuvik Petroleum Office created these regions. These regions are bound as an outer edge by a combination of the NRCan Canada Geopolitical 250,000 boudary polygon, as well as the NWT oil and gas grid. The mainland portion of these regions, i.e. not the arctic islands, has the boundary edges of the Yukon / NWT or Nunavut / NWT border defined by the NRCan Canada Geopolitical 250,000 boundary polygon. Internally, the eastern edges of the Cameron Hills, Central Mackenzie Valley, Mackenzie Delta and Arctic Islands, and the southwester portion of the Mackenzie Delta Arctic Islands region are defined by the NWT oil and gas grid cells, where there is hydrocarbon potential greater than low/moderate according to the NTGO Open File Report 2005-004. Since there is little likelihood of any oil and gas interest where there is little to no potential on the easter portion of the Northwest Territories, as the sedimetary basin pinches out and only hard rock basement geology exists in most of the easter portion of the mainland NWT. There is one oil and gas licence in the arctic islands, and it cannot be determined at this point in time what future exploration there may be in the arctic islands, therefore from the entirity of the Mackenize Delta existing oil and gas licencing including the single oil and gas licence all the way to the nothern portion of the NWT oil and gas grid are included together. |
