Modification of ΔlogR method and Nonlinear Regression Application for Total Organic Carbon Content Estimation from Well Logs

ΔlogR method is one of the most widely utilized techniques for estimation Total Organic Carbon (TOC) content form well logs. The traditional reveals assumption linear relationship between logarithmic resistivity and porosity log. In this study, modified by means integral calculus to acquire actual trend Furthermore, unlike method, maturity additionally represented with logarithm organic maturation temperature. Nonlinear regression applied optimize unclear organized parameters required computation TOC content. final forms equations are observed be appropriate nonlinear application. estimations improved versions in case methods unsatisfactory due related expressed above. With introduced methodology unconventional reservoirs source rocks can more accurately calculated.
