FJS-22 merupakan sumur deviasi di Lapangan Handil karena semua reservoir gas di
sumur ini telah diproduksi, maka sumur ini diusulkan menjadi kandidat Gas Lift Macaroni.
Pada sumur ini di lakukan plug and squeeze cementing untuk mengisolasi reservoir pada
interval 2116,5-2118 M.
Pertama-tama di lakukan yaitu snubbing preparation yang dimana melakukan
daftar periksa prosedur perawatan preventif pra-kerja untuk semua peralatan, memastikan
tersedia air dan bahan kimia yang cukup sebelum memulai pekerjaan. Material slurry pada
penyemenan ini terdiri dari semen, air dan additive. Hasil dari perhitungan adalah
mengetahui berapa jumlah volume semen yang akan di gunakan untuk penyemenan,
jumlah total air yang digunakan serta additive apa saja yang akan digunakan dalam
penyemenan tersebut. Penyemenan ini menggunakan rig snubbing HWU dan melakukan
pengujian di dapatkan komposisi dari slurry composition. Ada tiga stage penyemenan yang
akan dilakukan dengan snubbing. Pada stage pertama, snubbing akan memompa 16,2 Bbls
semen pada tubing pada interval 2780-3110 M + 22,49 Bbls volume displacement air. Pada
stage kedua, snubbing akan memompa volume gel 15,2 Bbls + 20,17 Bbl volume
displacement air. Snubbing akan memompa 5,9 Bbls semen pada tubing pada interval
2350-2470 M + 18,3 Bbls volume displacement air. Pada stage tiga, snubbing akan
memompa 4.4 Bbls weighted gel + 17.24 Bbls displacement air dan melakukan tes
injektivitas.
Berdasarkan hasil injektivitas, snubbing memompa 6,3 bbls volume semen pada
tubing pada interval 2160-2260 M termasuk 1,4 Bbls volume semen dengan squeeze ke
dalam reservoir interval 2116,5-2118 M

FJS-22 is a deviation well in Handil Field because all gas reservoirs in this well
have been produced, so this well is proposed to be a candidate for Macaroni Gas Lift. In
this well is plug and squeeze cementing to isolate the reservoir at intervals of 2116.5-2118
M.
First of all, snubbing preparation is done in advance, which is to check the prework preventive maintenance procedures for all equipment, then make sure there is
enough water and chemicals before starting the work. The slurry material in this
cementing consists of cement, water and additives. The result of this calculation is to know
how much cement volume will be used for plug and squeeze, the amount of cement that
will be used in each session, the total amount of water used and what additives will be
used in the cementing. This cementing uses HWU Snubbing Rig and previously conducted
lab tests first where after testing obtained composition from slurry composition. There are
three stages of snubbing to be done with Snubbing. In the first stage, snubbing will pump
16.2 Bbls of cement on the tubing at intervals of 2780-3110 M + 22.49 Bbls of water
displacement volume. In the second stage, snubbing will pump gel volume 15.2 Bbls +
20.17 Bbl water displacement volume. Snubbing will pump 5.9 Bbls of cement on the
tubing at intervals of 2350-2470 M + 18.3 Bbls of water displacement volume. In stage
three, snubbing will pump 4.4 Bbls weighted gel + 17.24 Bbls displacement of water and
perform an injectivity test.
Based on the results of injectivity, snubbing will pump 6.3 bbls of cement volume in
tubing at intervals of 2160-2260 M including 1.4 Bbls of cement volume by squeezing into
reservoir intervals of 2116.5-2118 M
