This paper presents a method for calculating hydrocarbon density from logs. Empirical relations between bulk volume hydrocarbon and the volume of hydrocarbon seen by the density and neutron logs are derived. An approximate relation is developed for excavation effect on the neutron log. Approximating polynomials for the relationship between hydrocarbon density and the log response of the hydrocarbon seen by the density and neutron logs are derived. A calculator program is presented which computes hydrocarbon density, porosity, and water saturation using these relations. If the hydrocarbon is a mixture of oil and gas, a means of estimating oil and gas saturations is provided by the program. Finally, an example is given to illustrate the use of the program.
