Miftah, Pada dasarnya, skala log yang digunakan dalam Neutron-Density log adalah 2.71 Density = 0 Porosity (HI). Jadi skala log bisa menggunakan skala limestone atau skala sandstones asal mengunakan "compatible scale" dengan neutron Porosity. Matrix log dalam prosesing bisa menggunakan matrix limestone atau matrix sandstones tergantung referensi perusahaan.

Saya akan melakukan pengukuran wireline logging di sand dominated sequence. Bacaan density dan neutron log di sumur-sumur sebelumnya selalu nampak cross over baik itu di water, oil maupun gas zone. Menurut beberapa refferensi yang baru saya baca hal ini bisa diakibatkan karena proses perekaman porosity log nya menggunakan limestone scale. Kalau saya putuskan untuk menggunakan sandstone scale pada saat perekaman logging, apakah bisa menjadi solusi? Atau malah bisa menimbulkan masalah lain, mengingat kalau tidak salah para kontraktor wireline logging selalu mengkalibrasi porosity tool-nya dengan batugamping.
