Sumur “TLD-01” Lapangan Jatibarang merupakan sumur baru yang akan
diproduksikan dengan metode artificial lift berupa Electric Submersible Pump.
Electric Submersible Pump dipilih berdasarkan screening criteria yang paling
sesuai dengan data Ekploitasi pada Juni 2020. Laju alir minimum yang diharapkan
sebesar 495 Bopd dengan tekanan alir dasar sumur sebesar 4000 psi, water cut yang
tergolong medium to high yaitu sebesar 65%, dan GLR sebesar 102463 Scf/Stb. Hal
tersebut dapat menyebabkan menyebabkan masalah gas lock, sehingga diperlukan
perencanaan design ESP yang sesuai dengan kondisi sumur tersebut.
Perencanaan design ESP diawali dengan menghitung IPR dengan metode
IPR Vogel dengan Qmax sebesar 613 Bfpd. Laju alir target Sumur “TLD-01” pada
70% dari Qmax-nya sebesar 430 Bfpd. Tahapan dalam perencanaan ESP meliputi
pengumpulan data, pembuatan kurva IPR, penentuan laju alir pompa, penentuan
kedalaman pompa, perhitungan Pump Intake Pressure, perhitungan Total Dynamic
Head, pemilihan pompa dan jumlah stages, serta pemilihan peralatan pendukung
ESP di permukaan.
Hasil pemilihan pompa yang sesuai dengan rate optimum dengan
sensitivitas jumlah stages untuk Sumur “TLD-01” adalah D460N/60Hz/43 stages.
Pompa diletakkan pada kedalaman 7800 ft diatas perforasi, dengan menggunakan
Rotary Gas Separator REDA 400/400 VGSA D20-60, 400/400 dengan efisiensi
sebesar 80% menghasilkan kadar gas bebas 2% dan nilai turpin 0.004<1 yang
menunjukkan tidak ada gangguan pada pompa. Pemilihan peralatan pendukung
ESP untuk mendukung kinerja pompa di antaranya: Tipe motor yang digunakan
adalah 400 Series ES Carbon Steel Motor. Spesifikasi untuk Sumur “TLD-01”
adalah 50 HP / 509 V / 62 A. Kabel dipilih dengan jenis RedaBlack*ESP Power
Flat Cable No. 4 Conductor tipe ETBEF-300 AWG#4 Conductor 4/Solid dengan
OD 1,5 inch. Transformator dipilih dengan tipe Three Phase Dual Wound, OISC
Type, 75 kVA -7200/12470Y Primary dan VSD dipilih dengan tipe SpeedStar 2000
Plus VSDs-NEMA 3R, 6 Pulse, 122°F [50°C] Ambient Temperature Rated @480V
output 100 A.

ABSTRACT
PLANNING OF DESIGN ELECTRIC SUBMERSIBLE PUMP IN
TLD-01 WELL WITH HIGH GLR IN PERTAMINA EP ASSET 3
JATIBARANG FIELD

The "TLD-01" well in the Jatibarang Field is a new well that will be
produced using the artificial lift method in the form of an Electric Submersible
Pump. The Electric Submersible Pump was selected based on screening criteria
that best fit the Exploitation data for June 2020. The flow rate required minimum is
495 Bopd with a well bottom flow pressure of 4000 psi, the water cut is classified
as medium to high, which is 65%, and the GLR is 102463 Scf/Stb . This can cause
gas lock problems, so it is necessary to plan an ESP design that is in accordance
with the conditions of the well.
ESP design planning begins with calculating the IPR using the IPR Vogel
method with a Qmax of 613 Bfpd. The target flow rate of Well “TLD-01” at 70%
of its Qmax is 430 Bfpd. The stages in ESP planning include data collection, making
IPR curves, determining pump flow rates, determining pump depth, calculating
Pump Intake Pressure, calculating Total Dynamic Head, selecting pumps and the
number of stages, and selecting ESP supporting equipment on the surface.
The results of selecting the pump according to the optimum rate with the
sensitivity of the number of stages for the "TLD-01" well is D460N/60Hz/43 stages.
The pump is placed at a depth of 7800 ft above the perforation, using a Rotary Gas
Separator REDA 400/400 VGSA D20-60, 400/400 with an efficiency of 80%
producing a free gas content of 2% and a turpine value of 0.004<1 which indicates
no interference with the pump . The selection of ESP supporting equipment to
support pump performance includes: The type of motor used is the 400 Series ES
Carbon Steel Motor. The specifications for the Well “TLD-01” are 50 HP / 509 V
/ 62 A. The cable is selected with the type of RedaBlack*ESP Power Flat Cable No.
4 Conductor type ETBEF-300 AWG#4 Conductor 4/Solid with 1.5 inch OD. The
transformer was selected with the type of Three Phase Dual Wound, OISC Type, 75
kVA -7200/12470Y Primary and the VSD was selected with the type SpeedStar 2000
Plus VSDs-NEMA 3R, 6 Pulse, 122°F [50°C] Ambient Temperature Rated @480V
output 100 A
