Introduction

The recent steep rise and anticipated stable high North American natural gas prices has triggered a significant amount of interest in exploration opportunities north of Latitude 60°. Important gas reservoirs are known to occur in Alaska, the MacKenzie Delta-Southern Beaufort Sea, Colville Hills, Eagle Plain, and in the Liard region. The area between Liard to the south, and the Central Mackenzie Valley to the north, has been a relatively quiet exploration region. However, the possible commercial discovery at Summit B-44 has generated renewed exploration interest in the area.

Existing production and infrastructure in the Liard region assists the economic value of future discoveries. The relatively close proximity to transport suggests that relatively modest gas fields found near Liard may be tied in to southern markets sooner than the larger, but more remote, gas resources north of 68°. Future new pipelines transporting gas from the Mackenzie Delta will provide additional exploration activity along the proposed pipeline route.

Building on our recently completed extensive integrated Regional Geological and Geophysical assessment of basins from 65° - 70° N (Mackenzie Valley study), and exploration analysis of the deep Devonian in northeastern British Colombia, Petrel Robertson Consulting Ltd. (PRCL) is proposing to conduct a regional multi-disciplinary exploration assessment of the Cambrian to Cretaceous succession of the region between 60° and 65° North latitude and 115° to 126° West longitude (Figure 1).

PRCL's completed northern frontier studies (Mackenzie Valley, Mackenzie Delta) comprise:

9600 m of browsable digital core photo library linked to core descriptions (AppleCore), core analysis and petrography.
Independently-generated stratigraphic tops database, regional and pool scale cross-sections, gross isopach, and porosity maps.
80 wells with biostratigraphic information (Mackenzie Delta only)
20,000 km of interpreted seismic data, including 160 wells with checkshot surveys, time and depth surfaces, and structural analysis.
Hydrodynamic analysis based on 2085 well tests, summarized by: Pressure vs Elevation plots; potentiometric surface, pool delineation, water and gas chemistry maps; and identification of damaged/potential bypassed pay zones.
Geochemistry / source rock / basin analysis, based upon a 163 well geochemical database. Thirty-one 1-D basin analysis models were undertaken in the course of this work.
