idealnya kita ambil yang velocity shale saja.
tetapi bagaimana bisa dilakukan filter, jika
lapisannya belum di bor.
maka diambil 'aman'nya saja , sambil dievaluasi saat ngebor.

Mungkin hubungan yang dibuat terlampau simple ya, velocity turun=pp naik.
Karena penyebab naik turunnya velocity kebanyakan berhubungan dengan
litologi dan fluida pengisi, kadang2 berhubungan overpressure. Saya pribadi
sih nggak terlampau nyaman memprediksi pressure dengan menggunakan velocity
logs.

kebalik Mas Iwan,
velocity turun, pp naik.
apakah benar2 overpressure atau bukan,
utk velocity look ahead, tidak bisa di check.
kecuali dg di drill. kecuali well known area.
tapi kalau udah well known ngapain juga di look ahead.
cara yang paling 'murah' dan gampang , di flow check saja.
kalau gain ya ditambah mw, kalau nggak yaa continue drilling.
secara sistematis tiap 30m-50m flow check.

Kalau velocitynya turun apakah berarti PPnya turun?? karena kalau benar
begitu, berarti low velocity akibat gas dan overpressure bisa dianggap
sebagai low PP ya???

Mas Iwan,
Dilihat saja velocity trendnya.
Seperti melihat sonic trend. Cuma, apakah bisa dihitung PPP-nya dengan
eaton/metoda lain, saya belum mencoba.

Maaf, bagaimana cara melihat pressure trend dr VSp look ahead???

Kejadiannya sudah agak lama 1 1/2 th yg lalu.
Waktu itu kita run VSP look ahead.
Dan mendapatkan dua reverse trend.
Reverse trend yang pertama tidak ada apa-apa. Cuma ada carbonate streak.
Reverse trend yang kedua, seharusnya dibawah TD plan, tetapi akhirnya
kita dapat 'kick' duluan. Kalau dihitung perkiraan 50m-an.
Saya tidak sempat mendapat kesempatan mengevaluasi. Why dst..
Maklum saya cuma wellsite geologist.
Waktu itu kita gunakan Schlumberger. Mereka juga yang
melakukan look ahead.
Mudah2an saya bisa cari2 filenya, dan ngoprek2 siapa tahu ada yang
mengevaluasi, kenapa gagal, dst.

Kalau kontras-nya terdeteksi, bukan yang salah interpretasi (prognosis)
nya?
Kalau boleh tahu, seberapa besar meleset-nya dalam satuan jarak? Berapa
jauh
prediksi-ny dari drillbit location?
