apa yg dikemukakan oleh rekan noel dan agus priyono, tampaknya sangat ideal, dan tentunya tidak jauh berbeda dengan prakterk di industri migas.
namun dari yg saya ketahui, katanya praktek pemboran utk eksplorasi batubara di indonesia, pada umumnya adalah penggunaan gamma-ray dan density saja (mungkin plus sp). mungkin hal ini dikonfirmasikan? alasannya sederhana: utk memastikan bahwa ada batubara di dalam lubang sumur pemboran tsb, dan yg pasti harganya lebih murah. kalo mau melakukan pengukuran yg lain, neutron, resistivity, apalagi sonik, mahal bro.... salam, syaiful 2011/1/16 Rovicky Dwi Putrohari <[email protected]>: > Terimaksih infonya. > Apakah juga ada petrophysical analysis ?
