Abstract
Methods and systems may include obtaining, from a rock coring system, rock samples, determining, using a nuclear magnetic resonance system, a hydrocarbon-filled porosity for each rock sample, determining, using a pyrolysis system, a concentration of hydrocarbons within each rock sample, and determining, using regression analysis, a relationship between the concentration of hydrocarbons and the hydrocarbon-filled porosity. The methods and systems may further include obtaining, from a well logging system, well logs along a well that penetrates an in situ rock, determining a total hydrocarbon-filled porosity for the in situ rock using the well logs, and obtaining the relationship. The methods and systems may still further include determining an in situ concentration of hydrocarbons within the in situ rock using the relationship and the total hydrocarbon-filled porosity and determining a recovery factor for the in situ rock based on the in situ concentration of hydrocarbons.
