AbstractThis study presents the first independent evaluation of the in place hydrocarbon resources for the Macasty Formation on Anticosti Island. The evaluation uses the dual porosity model of the GSC. The data consists of all public domain information as well as confidential data provided by the operators on the island.
Our evaluation indicates significant volume of both oil with a best estimate or P50 of 32.3 billion barrels of oil (BBO) with maximum (P5) of 55.4 and minimum (P95) of 17.1 BBO and for natural gas with a best estimate or P50 of 52.4 trillion cubic feet (TCF) with maximum (P5) of 85.2 and minimum (P95) of 29.0 TCF. However, the comparison of the maximum (55.4 BBO / 85.2 TCF) and minimum (17.1 BBO / 29.0 TCF) resources in place illustrates a significant uncertainty on the evaluation most likely related to the relative low density and quality of the data (spatial coverage, diverse acquisition methods).
Previous industry estimates suggest an in-place P50 resource of 42.9 billion barrels of oil equivalent, a value that lump together oil and gas based on a thermal equivalence of 1 barrel of oil equivalent for 6000 cubic feet of gas. Our P50 result is 42.1 billion of barrels of oil-equivalent. From these results, a ratio of 78% oil to 22% gas is proposed as in-place resource on the island. Because of the lack of production data, no attempt was made to evaluate the recovery portion of the in-place resource.
Summary(Plain Language Summary, not published)
The GSC evaluates the in place oil and gas resource for the Macasty Formation on Anticosti Island. The data consists of all public domain information (GSC and MRNQ) as well as confidential data provided by the operators on the island (Hydrocarbons Anticosti L.P. and Junex Exploration). Our evaluation indicates significant volume of resources for both oil (average of 28.9 billion barrels of oil) and gas (average of 46.6 trillion cubic feet) although given the relative low density and quality of the data (spatial coverage, methodology of acquisition), a wide uncertainty is present as expressed by high and low estimates. Previous industry estimates suggest an in-place mean resource of 43 billion barrels of oil equivalent, a value that lump together oil and gas based on a thermal equivalence of 1 barrel of oil equivalent for 6000 cubic feet of gas. Because of the lack of production data, no attempt was made to evaluate the recovery of the in-place resources.
