Lapangan “LAZ” merupakan salah satu lapangan minyak tua yang berada di Kota
Prabumulih, Provinsi Sumatra Selatan yang mulai berproduksi pada tahun 1947.
Seiring berjalannya waktu, produksi air pada Lapangan “LAZ” akan meningkat,
hingga pada akhir 2022 nilai water cut rata-rata lapangan mencapai 94%. Struktur
“DAL” sebagai salah satu struktur tua pada Lapangan “LAZ” yang mulai
berproduksi pada tahun 1949 dengan water cut 0% dan seiring waktu cenderung
mengalami kenaikan hinga pada tahun 2022 nilai water cut menyentuh 97%.
Pada Struktur “DAL” Lapangan “LAZ” dilakukan kegiatan optimasi produksi yaitu
perencanaan reaktivasi dimana sebagian besar sumuran memiliki tingginya nilai
water cut (high water cut) dan banyak sumur suspended/shut-in. Perencanaan
reaktivasi sumur shut-in pada Struktur “DAL” dimulai dengan melakukan
screening sumur dan lapisan dengan parameter sumur high water cut (WC>90%),
ketersediaan data lumping, kumulatif produksi yang tidak melebihi cut-off
strukturan, serta nilai recovery factor yang dianalisa berdasarkan perbandingan
kumulatif produksi dengan inplace radius sumuran dengan perhitungan recovery
factor berdasarkan data SCAL, analisa permasalahan high water cut pada sumur
dengan melakukan analisa water oil ratio dengan metode Chan’s Diagnostic Plot,
melakukan analisa menggunakan CBL (Cement Bond Log) untuk mengetahui
kondisi ikatan (bonding) semen, analisa korelasi sumur, analisa decline (DCA)
dengan metode Trial Error dan X2 Chi-square Test dan melakukan forecast untuk
memperkirakan produksi di masa yang akan datang, hingga melakukan analisa
keekonomian. Perencanaan reaktivasi pada Sumur DAL-031 sebagai sumur shut in
dengan produksi terakhir pada 21 Januari 2016 dilakukan untuk meningkatkan
perolehan minyak pada Lapangan “LAZ”.
Pada perencanaan reaktivasi Sumur DAL-031 diperoleh oil gain 47.04 bopd dengan
tipe Exponential Decline dan forecast selama 8 tahun. Dilakukan analisa
keekonomian dengan menghitung lima indikator keekonomian (NPV, IRR, POT,
PIR, DPIR) serta analisa sensitivitas, diperoleh bahwa perencanaan reaktivasi
Sumur DAL-031 layak dan ekonomis untuk dikembangkan.
Kata kunci: high water cut, sumur shut in, reaktivasi sumur, lapangan minyak tua.

ABSTRACT
PRODUCTION OPTIMIZATION WITH SHUT-IN DAL-031

The "LAZ" Field is one of the mature oil fields located in Prabumulih City, South
Sumatra Province which began production in 1947. Over time, water production in
the "LAZ" Field will increase, until the end of 2022 average field water cut value
reaches 94%. The "DAL" structure is one of the old structures in the "LAZ" Field
which started production in 1949 with a 0% water cut and over time tends to
increase until in 2022 the water cut value reaches 97%.
In the “DAL” Structure of the “LAZ” Field, production optimization activities are
carried out, namely reactivation planning where most of the wells have a high water
cut value and many suspended/shut-in wells. Planning for reactivation of shut-in
wells on the "DAL" structure begins with screening of wells and layers with well
parameters such high water cut (WC>90%), availability of lumping data,
cumulative production that does not exceed the cut-off structure, recovery factor
value that is analyzed based on comparison of cumulative production with inplace
radius wells and calculation of recovery factor based on SCAL data, analysis of
high water cut problems in wells by analyzing water oil ratio using Chan's
Diagnostic Plot method, analyzing using CBL (Cement Bond Log) to determine
cement bond conditions, well correlation analysis, decline analysis (DCA) using
the Trial Error and the X2 Chi-square Test method, perform forecasts to estimate
future production, and also economic analysis. Planning for reactivation of the
DAL-031 well as a shut-in well with the last production on January 21, 2016 was
carried out to increase oil recovery in the "LAZ" field.
The planned reactivation of the DAL-031 ell, an oil gain of 47.04 bopd was
obtained with the Exponential Decline type and forecast for 8 years. Economic
analysis was carried out by calculating five economic indicators (NPV, IRR, POT,
PIR, DPIR) as well as sensitivity analysis, it was found that the plan for reactivation
of the DAL-031 Well is feasible and economical to develop.
Keywords: high water cut, shut in well, well reactivation, mature oil field.
