Abstract

Accurate estimation of rock property is essential and needed for efficient reservoir characterization. Insufficient permeability measurement makes predictions a difficult problem. Till date, it has been a difficult task to measure permeability using wire line logs sometimes it becomes capital intensive to employ other methods. In this paper, a correlation was developed which enables fast and easy determination of permeability for Niger Delta reservoir. Data were obtained from over 250 reservoirs and analyzed. About 247 data points was used for the development of the correlation. A general non-linear multiple variable regression analysis was performed on the data using DATAFIT 9.0. The statistical parameter returned shows a good match of the developed correlation and the field data. An R2 value of 0.99 and an absolute average total percentage error of 0.009106 were obtained. A permeability cross plot was made to check the reliability of the model. Comparison with other available correlations where also made to check how closely they match the actual field data. The correlation will predict best within the range of porosity and saturation values used
