Below is a procedure for estimating expulsion efficiency.
Below is a procedure for estimating expulsion efficiency.
# Estimate the original kerogen content of the rock using TOC values measured from source rock samples.
# Model the original [[Petroleum generation|hydrocarbon generation]] potential of the source rock using the estimated original kerogen content.
# Measure the volume of hydrocarbons expelled during pyrolosis (S2).
# Estimate the actual expelled hydrocarbon volume by subtracting the S2 value from the original hydrocarbon generation potential of the source rock.
# Calculate efficiency by dividing the expected volume of expelled hydrocarbons from the actual volume of hydrocarbons generated.
