Pak Trisakti, Mungkin overlap di Vp itu yang menjadi masalah. Persamaan EI memiliki komponen pangkat ~ tan(theta) pada Vp yang nilainya makin besar kalau theta (sudut) makin besar. Jadi kalau ada overlap di Vp, mungkin ada impaknya di EI pada sudut besar.
Bisa juga kombinasi Vp, Vs, dan density memang memungkinkan overlap EI pada sudut besar.

Keduanya terpisah sangat baik di domain Vs dan sedikit overlap di Vp.

LL -----Original Message----- From: Trisakti Kurniawan [mailto:sakti_...@yahoo.com] Sent: Monday, March 15, 2010 1:12 PM To: HAGI-net; IAGI-net Subject: [iagi-net-l] Perilaku EI Bapak2 dan Ibu2, Saat melakukan analisa crossplot antara sand dengan shale pada domain SI (shear impedance), kedua litologi tersebut bisa terpisah..begitu juga pada domain AI-nya. Namun saat saya coba bermain dengan sudut (EI)..semakin jauh saya "mainkan"..di far offset bahkan ultra far kenapa keduanya semakin overlap? Apa arti fisis dari hal ini ya? Mohon pencerahannya. Terima kasih.
