VSP behind casing itu apakah maksudnya running VSP in a cased hole? Jika demikian, selama kita meletakkan downhole reciever di posisi " good cement bond log" data VSP nya akan excellent, lebih bagus dari pada Open hole. Saya lebih suka running vsp di cased hole karena lebih cepat, tidak ada resiko stuck, perfect coupling dan data seismicnya excellent. Tapi jangan running di double casing, gak bisa first break picking dan biasanya datanya tidak bisa digunakan( kata pak Leo Anis tak ada media penjalaran ).
Mudah-mudah bisa melengkapi.

Oleh karena itu sinyal akan tertangkap dengan bagus (hampir sama jika OH) kalau semennya bagus, artinya casing-semen-formasi jadi satu kesatuan dan tdk. ada gap antara casing dan semen dan/atau semen dan formasi. Bisa diperjelas apa yang dimaksud dengan pernyataan "hasilnya setelah dikalibrasi"? Dikalibrasi dgn. apa? kenapa harus dikalibrasi?
