Abstract
ABSTRAK
Telah dilakukan penelitian dengan memaparkan karakteristik reservoar
menggunakan metode Forward dan Inversion Seismic Modeling dengan Analisa
AVO pada sumur Sepinggan, Cekungan Kutai, Kalimantan Timur.
Pemodelan respon AVO, diperoleh dari nilai koefisien refleksi dengan
perhitungan sudut datang 0°-40° menggunakan persamaan Shuey, nilai koefisien
refleksi diperoleh dari nilai impedansi akustik berdasarkan data log sonik (DTCO
dan DTSM) dan data log densitas (RHOB) dari sumur Sepinggan.
Pemodelan Impedansi Akustik dilakukan menggunakan perhitungan
manual metode inversi rekursif. Hasil korelasi pemodelan Forward impedansi
akustik dan pemodelan Inversion impedansi akustik menunjukan korelasi yang
baik, dengan besarnya korelasi 0,9.
Kata Kunci : Respon AVO, impedansi akustik, perhitungan manual metode inversi rekursif
ABSTRACT
It has been studied by describing the characteristics of the reservoir using
the Forward Seismic Modeling and Inversion with AVO analysis on the well
Sepinggan, Kutai Basin, East Kalimantan.
The model of the AVO response, obtained from the calculation of the
value of reflection coefficient with incidence angle 0 ° - 40 ° using Shuey’s
equation, the reflection coefficient obtained from the acoustic impedance, based
on the sonic log data (DTCO and DTSM) and density log data (RHOB) from well
Sepinggan.
Acoustic impedance modeling is done using manual calculations recursive
inversion method. The correlation results of acoustic impedance of the forward
modeling and acoustic impedance of the inversion modeling showed a good
correlation, with correlation magnitude 0.9.
Keywords: Response AVO, acoustic impedance, the manual method of inverse calculation recursivel
