| Abstract | : | Usage of Castagna’s relation by mean the P-wave log directly in estimation of the S-wave log gives a large error to the original S-wave log so that the result is not reliable for further analysis. This paper offers new method for S-wave log estimation based Castagna’s relation which is combined with fluid replacement modeling method based on Biot-Gassman substitution and the use of petro physical data as input. The S-wave log result of the offered estimation method has a small error to the original S-wave log so that more reliable and accurate for further analysis.The offered method could be used for S-wave log estimation in various lithology such as sand, limestone, dolomite and shale.The S-wave log result of the offered estimation method has successfully used for cross plot analysis of Vp/Vs ratio as function of acoustic impedance and Gamma Ray for delineation of sandstone bearing hydrocarbon from two different field. . |
