Sumur AKS-27 merupakan sumur minyak dengan tipe komplesi dual
monobore dimana sumur tersebut sudah tidak berproduksi karena tekanan
reservoirnya tidak mampu lagi mengalirkan minyak ke permukaan secara alami.
Hasil dari BHP survey menunjukan fluid level di kedalaman 1985 ft dan seluruh
wellbore diisi dengan kolom minyak.
Agar sumur AKS-27 dapat mengalir kembali dilakukan perencanaan desain
coil tubing gas lift, meliputi mengetahui posisi fluid level, penentuan titik injeksi,
dan jumlah gas injeksi, sehingga didapatkan kembali laju produksi optimal sumur.
Dari analisa dan perhitungan yang dilakukan, didapatkan letak titik injeksi
pada kedalaman 3930 ft, gradient tekanan Pko 31 psi/1000ft dan jumlah gas injeksi
sebesar 193709.44 scf. Kemudian dibuat performa sumur setelah dilakukan
pemasangan coil tubing gas lift dan didapatkan kurva IPR dan VLP berpotongan.
Hal ini dapat disimpulkan bahwa sumur AKS-27 berhasil berproduksi kembali.

AKS - 27 wells are oil wells with completion type dual monobore where
the well has not productive because reservoir pressure can no longer drain the oil
to the surface naturally. The results of the survey showed BHP fluid level at a
depth of 1985 ft and the entire wellbore is filled with the oil column.
AKS-27 so that the well can flow back by planning the design of coil tubing
gas lift, covering determine the position of fluid level, determining the location
of the injection point, and the number of gas injection, so we get back optimal
production rate wells.
From analysis and calculations are done, get the location of the injection
point at a depth of 3930 ft, PKO pressure gradient at 31 psi / 1000ft and the
amount of 193709.44 scf of gas injection. Then made the performance of the
wells after the installation of coil tubing gas lift and IPR and VLP obtained curves
intersect. It can be concluded that the wells AKS-27 managed to produce back.
