“…7). This kind of discovery curve model is frequently used in the oil and gas industry to predict the total resource endowment of a petroleum field or province (e.g., Chen et al, 2000). In the central Arctic Zn-Pb District, the total number of showings is estimated to be about 135, of which 82 are known.…”

ABSTRACT. Exploration in the central Arctic Zn-Pb District took place in five phases: 1) an initial exploration period (1960 -70), during which most surface showings on Cornwallis and Little Cornwallis islands were found; 2) a discovery period (1971 -79), during which the buried Polaris ore body was discovered and its feasibility and viability established, new showings were found farther afield, and many showings received limited drill testing; 3) the production period , dominated by drilling at Polaris Mine; 4) an ore-replacement exploration period (1989 -2001), during which showings close to Polaris were extensively drilled, showings on Cornwallis Island drill tested, and new showings found and drilled farther away; and 5) a reclamation period (2002 -05), during which the infrastructure was removed and the mine site restored. Factors affecting the timing and rate of exploration were generally intrinsic to the region: 1) discovery of showings in 1960, 2) discovery of the Polaris ore body in 1971, 3) declining reserves between 1989 and 2002, 4) closure of the mine in 2002, 5) the short exploration season and difficult logistics, and 6) lack of competition. The external drivers of exploration were 1) oil-related exploration that led to the discovery of the Polaris showings, 2) the onset of regional exploration coinciding with spikes in the price of zinc, and 3) the surge in scientific interest in carbonate-hosted Zn-Pb deposits in 1967. Probabilistic, discovery-time curve analysis indicates that over 50 showings remain undiscovered. Because logistics controlled the target selection, the standard assumption of a logical discovery process (from largest target to smallest target) is likely invalid. This means that large, untested targets may still exist in the district.

“…Due to sampling bias in exploration (selective drilling) (Drew, Attanasi, & Schuemeneyer, 1988;Kaufman et al, 1975;Lee & Wang, 1985;Schuenemeyer & Drew, 1983), direct calculation of the lognormal distribution parameters may lead to biased distribution model. Chen et al (2000b) studied the impacts of exploration sampling on the estimation of lognormal parameters in this basin. The results show that selective exploration drilling had significant impact on the parameter estimation for gas and oil fields.…”

“…Therefore, b 1 and b 2 are set at 0.80 and 0.90, respectively. Chen et al (2000b) assessed the petroleum potential of the western Sverdrup Basin. In their assessment, around 100 oil and gas fields in the size range from 8.1 to 115 £ 10 6 m 3 oil equivalent, corresponding to pool area sizes from 919 to 50,018 ha were predicted to exist.…”

“…However, the growing demand for petroleum, particularly for natural gas, will make Sverdrup Basin one of the frontier basins for future reserve additions in North America. Second, a similar study predicting the locations of undiscovered petroleum resources was conducted by our research group using different techniques (Chen, Osadetz, Embry, Gao, & Hannigan, 2000b). This forms an ideal basis for the comparison of methods, as well as, providing a focus for the discussion of the advantages and drawbacks of each of these methods.…”

“…1) and are included in the Murray Harbour Formation. Between 1969 and 1986, 119 drilled wells, mainly in the western part of the Sverdrup Basin, led to the discovery of 8 oil and 25 gas pools (Chen et al, 2000). The Murray Harbour Formation has already been identified as one of the major source rocks for many of these hydrocarbon pools (Brooks et al, 1992).…”
