ANALISIS SEBARAN POROSITAS RESERVOAR BATUPASIR DENGAN MENGGUNAKAN METODE SEISMIK INVERSI IMPEDANSI AKUSTIK PADA LAPANGAN “TIYACI” FORMASI TALANG AKAR, CEKUNGAN SUMATERA SELATAN
Daftar Isi:
- The analysis of the development determination of new well Talang Akar Formation in “Tiyaci” field has been done by using acoustic impedance inversion seismic method. In this study comparing three inversion seismic methods, that is model based method, bandlimited method, and maximum likelihood sparse spike method. From the comparison analysis of the three methods, the best inversion is a model based inversion method with a correlation of 0.999. Using acoustic impedance inversion seismic and crossplot between P-impedance log to density log and P-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 21,000-23,000 (ft/s)*(g/cc), 2.32-2.35 g/cc, 20-23%, and this area is in Southeast of the study area.
