RINGKASAN
Pemboran sumur “FI-010” di Lapangan “TK” merupakan sumur eksplorasi,
pada saat operasi pemboran berlangsung hingga target kedalaman tidak terdapat
masalah, setelah mematikan pompa dan hendak mencabut rangkaian terjadi
problem well kick di kedalaman 6218 ft TVD / 6812 ft MD yang ditandai dengan
tetap adanya aliran walaupun pompa telah dimatikan.
Dalam melakukan evaluasi ini, langkah awal yang dilakukan adalah
pengumpulan data lapangan, meliputi data rencana pemboran dan data pelaksanaan
menggunakan grafik presure window dan masterlog. Selanjutanya menentukan
tekanan formasi, menentukan tekanan hidroststik, menentukan pressure loss untuk
menentukan tekanan hidrodinamik, menentukan volume lumpur untuk mencapai
KMW dan jumlah sack barite yang digunakan, menentukan tinggi jumlah stroke
pompa untuk membunuh kick, menentukan interval waktu pengontrolan selama
penanggulangan well kick, menentukan (ICP) Initial Circulation Pressure dan
(FCP) Final Circulation Pressure, menentukan pressure drop per stroke pada
pompa, menentukan (ECD) Equivalent Circulating Density , menentukan (BHCP)
Bottom Hole Circulating Pressure , menentukan Harga Maximum Allowable Mud
Weight (MAMW), menentukan Maximum Allowable Casing Pressure (MACP),
menentukan harga SIDP setelah sumur dimatikan. Selanjutnya dilakukan
penangggulangan well kick menggunakan metode Engineer.
Berdasarkan hasil perhitungan, tekanan formasi pada kedalaman 6218 ft
sebesar 3522 psi sudah cukup ditanggulangi dengan KMW sebesar 10.9 ppg
sehingga dibutuhkan penambahan barite sebesar 1443.355707 sack. Dari hasil
perhitungan didapatkan Initial Circulating Pressure (ICP) sebesar 633 psi dan
Final Circulating Pressure (FCP) sebesar 174 psi. Jumlah stroke pompa yang
dibutuhkan untuk mematikan kick sebesar 6958 strokes dengan waktu sirkulasi
selama 117.94 menit. Well kick berhasil ditanggulangi yang ditandai dengan tidak
adanya aliran pada saat pompa lumpur dimatikan dan harga SIDP yang
menunjukkan nilai 0 psi.

ABSTRACT
The drilling of the "FI-010" well in the "TK" Field is an exploratory well,
during the drilling operation there were no problems with the target depth, after
turning off the pump and about to remove the circuit there was a well kick problem
at a depth of 6218 ft TVD / 6812 ft MD marked flow even though the pump has been
turned off.
In carrying out this evaluation, the initial step taken was field data
collection, including drilling plan data and execution data using pressure window
charts and masterlogs. Next determine the formation pressure, determine the
hydrostatic pressure, determine the pressure loss to determine the hydrodynamic
pressure, determine the volume of mud to reach KMW and the number of sacks of
barite used, determine the height of the number of pump strokes to kill the kick,
determine the control time interval during well kick countermeasures, determine (
ICP) Initial Circulation Pressure and (FCP) Final Circulation Pressure, determine
the pressure drop per stroke on the pump, determine (ECD) Equivalent Circulating
Density, determine (BHCP) Bottom Hole Circulating Pressure, determine
Maximum Allowable Mud Weight (MAMW) Price, determine Maximum Allowable
Casing Pressure (MACP), determines the SIDP price after the well is shut down.
Then the well kick countermeasures are carried out using the Engineer's method.
Based on the calculation results, the formation pressure at a depth of 6218
ft of 3522 psi is sufficient to overcome with a KMW of 10.9 ppg so that an additional
barite of 1443.355707 sacks is needed. From the calculation results obtained Initial
Circulating Pressure (ICP) of 633 psi and Final Circulating Pressure (FCP) of 174
psi. The number of pump strokes needed to turn off the kick is 6958 strokes with a
circulation time of 117.94 minutes. The well kick has been successfully resolved
which is indicated by no flow when the mud pump is turned off and the SIDP value
shows a value of 0 psi.
