RINGKASAN
EVALUASI POMPA SUCKER ROD TERPASANG
SUMUR ”FZ-01” LAPANGAN ”ABR”
PT PERTAMINA EP CEPU

(Program Studi Sarjana Teknik Perminyakan)
Sumur kajian FZ-01 terletak di Lapangan ”ABR” yang termasuk wilayah
kerja PT Pertamina EP Cepu Regional 4 Zona 11 Field Cepu. Sumur FZ-01
berproduksi dengan artificial lift jenis sucker rod pump dengan tipe C-114D-143-
64 dan grade rod API C. Pompa dipasang pada kedalaman 2615.39 ft, dengan
kecepatan pompa 6 SPM, panjang langkah 54 in, dengan water cut 72.83% Sumur
FZ-01 berproduksi dengan QL sebesar 70.04 Blpd dan QO sebesar 19.03 Bopd.
Efisiensi volumetris pompa SRP yang terpasang pada Sumur FZ-01 sebesar 69.45
%. Evaluasi sucker rod pump pada Sumur FZ-01 dilakukan karena nilai efisiensi
volumetris pompa terpasang kurang dari 70%.
Metode dalam penyusunan skripsi ini adalah melakukan evaluasi sucker rod
pump terpasang berdasarkan data dynamometer card, beban-beban pada pompa,
dan efisiensi volumetris pompa. Tahapan dalam pengerjaan skripsi ini adalah
pengumpulan data, menganalisa produktivitas formasi, dan melakukan evaluasi
pompa terpasang. Evaluasi pompa terpasang dilakukan menggunakan data
dynagraph, data well profile, data pompa terpasang, dan data produksi.
Analisa secara kualitatif dynamoneter card Sumur FZ-01 mengindikasikan
adanya problem kebocoran pada standing valve. Evaluasi pompa sucker rod
dilakukan dengan mengubah stroke length (S) sesuai dengan pumping unit
terpasang dan kecepatan pompa (N) terhadap laju produksi. Berdasarkan hasil
evaluasi, dapat dilakukan penggantian stroke length pada 64 in dengan kecepatan
pompa 5 spm, sehingga didapatkan QL sebesar 73.8 Blpd dengan QO sebesar 20.05
Bopd dan efisiensi pompa sebesar 72.5 %.
Kata kunci: Evaluasi, sucker rod pump, stroke length

ABSTRACT
EVALUATION OF SUCKER ROD PUMP ATTACHED
WELL “FZ-01” FIELD “ABR”
PT PERTAMINA EP CEPU

The FZ-01 study well is located in the "ABR" Field which is part of the
working area of PT Pertamina EP Cepu Regional 4 Zone 11 Cepu. The FZ-01 well
produces with an artificial lift type sucker rod pump with type C-114D-143-64 and
grade rod API C. The pump is installed at a depth of 2615.39 ft, with a pump speed
of 6 SPM, a stroke length of 54 in, with a water cut of 72.83% of the FZ-01 well
which produces 70.04 Blpd of QL and 19.03 Bopd of QO. The volumetric efficiency
of the SRP pump which was installed in the FZ-01 well is 69.45%. The optimization
of the sucker rod pump in the FZ-01 well was carried out because the volumetric
efficiency value of the pump installed was less than 70%.
The method used in this research is evaluating the installed sucker rod
pump based on data from the dynamometer card, the loads on the pump, and the
volumetric efficiency of the pump. The stages used in this thesis are collecting data,
analyzing formation productivity, and evaluating installed pumps. The evaluation
stage of installed pumps used dynagraph data, well profile data, installed pump
data, and production data.
Based on the qualitative analysis of the well FZ-01 dynamometer card, it
indicates there is a standing valve leak problem. The evaluation of the sucker rod
pump was obtained by changing the stroke length (S) according to the installed
pumping unit and pump speed (N) to the production rate. Based on the evaluation
results, the replacement of the stroke length at 64 in with a pump speed of 5 spm
produces 73.8 Blpd of QL with 20.05 Bopd of QO and 72.5% of pump efficiency.
