Aplikasi tekanan pori salah satunya adalah untuk penentuan zona bawah
permukaan. Zona bawah permukaan umumnya terdapat zona abnormal dan zona
normal. Zona abnormal disebut juga overpressure. Penentuan overpressure
penting dilakukan dalam bidang drilling hzard seprti penentuan berat lumpur serta
pemasangan casing. Penentuan overpressure dilakukan untuk mengantisipasi
erjadinya drilling hazard akibat loss atau kick. Data yang digunakan untuk
stimasi tekanan pori diantaranya data drilling dan data logging. Estimasi tekanan
pori dengan metode Eaton memanfaatkna data logging diantaranya data log GR
dan sonik. Estimasi tekanan pori akan valid apabila dikoreksi dengan data
pengeboran seperti data pengukuran tekanan langsung

abstract
One of application of pore pressure is for determining subsurface zone. The
subsurface zone generally has an abnormal zone and a normal zone. The abnormal
zone is also called overpressure. Determination of overpressure is important in the
field of drilling hazard such as determining the weight of the mud and the
installation of the casing. Determination of overpressure is to anticipate of driling
hazard accidents due to loss or kick. Data used to estimate pore pressures include
drilling data and logging data. Pore pressure estimation by Eaton method takes
advantage of logging data such as GR and sonic log data. Pore pressure estimation
will be valid when corrected with drilling data such as direct pressure
measurement data
