Mas Kartiko,
beberapa hal pernah terjadi adanya keyseat, tau toolnya nggak mau turun
walaupun dalam casing. Saya pernah ngalami bbrp kali, terutama waktu mau
run Sidewall core, ternyata toolnya nggak mau masuk walaupun masih di dalam
casing. Akhirnya pakai TLC.
Selain itu kalau pakai pipa bisa menghindari off-depth, karena pipa nggak
ada efek yo-yo, dan lagi biasanya pipa punya pipe-tally yg akurat dibanding
kabel (walaupun kabel ada kalibrasi diameter kabel). Sehingga kejadian
salah tembak (nembak interval yg salah) bisa dihindari.
rgds,

TCP = Tubing conveyed Perforation
Karena dengan pipa ya tidak takut dengan key seat, dog leg, sudut, dsb
yang sering jadi problem untuk perforation gun yang diantar dgn kabel
(wireline).
Tambahan ukuran bisa lebih besar ? karena diantar dengan besi, cuma ya
runningnya lebih lambat dibanding kabel.

gak tahu kepanjangannya) dan WCG (Wireline Casing Gun).
Itu lho untuk perforasi casing sebelum DST.
Thanks ya.
