Title: Ratio of petroleum to water during primary migration in Western Canada basin

Abstract

Studies on the mechanism of primary migration involve some estimate of how much oil is carried out of the source rocks with the expelled water. A few ppM hydrocarbon in water can be explained by a solution mechanism but an oil-phase migration mechanism would require a much higher concentration of oil in water. The calculation of the oil/water ratio of fluids expelled during compaction of the Western Canadian basin was made for latitudes 49 to 60/sup 0/N. A table shows the porosity loss for each rock type and the total volume of water expelled from the fine-grained sediments. This porosity decrease calculates as a water loss of about 480,000 cu km, equivalent to about 480 x 10/sup 12/ MT for this part of the Western basin. Calculations are also made for ultimate recoverable oil potential and the mass of oil that is released by a given mass of source rocks. Results indicate that the quantity of hydrocarbons released from the source beds stand at about 6 to 16 percent of that still in place. (MCW)
