Abstract

The analysis of the development determination of new well Baturaja Formation in “X” field has been done by using acoustic impedance inversion method. In this study comparing three acoustic impedance inversion method, that is model based method, bandlimited method, and maximum likelihood sparse spike method. From the comparison analysis of the three method is obtained the best method that is model based method with a correlation 0.998. Using acoustic impedance inversion and crossplot acoustic impedance log to density log and crossplot acoustic impedance log to porosity log, obtained the density and porosity distribution, respectively. From the analysis of the distribution, it can be determined a new well development area. The area has acoustic impedance, density, and porosity of 19,000-22,000 (ft/s)*(g/cc), 2.2-2.3 g/cc, 20% -22%, and this area is in Southeast of the study area.
