Masalah Liquid loading terjadi pada reservoir, dibawah laju alir kritis gas
liquid tersebut akan terendapkan dan menyumbat lubang perforasi serta
peralatan produksi seperti tubing dan peralatan lainnya. Alasan pemilihan
capillary string sebagai sistem artificial lift sangat efisiensi karena biaya
pemasangan cukup murah, mengurangi biaya produksi, dan proses instalasi
yang cepat.
Bedasarkan data data yang diperoleh maka pada sumur CVD lapangan
BLP-1 dilakukan pemasangan capillary string berukuran 4-1/2 x 3/8 inch pada
target depth 3152 mBRT berdasarkan data survei liquid level terpadat.
Pada sumur CVD disetting laju injeksi surfactan sebesar 153 liter per hari
untuk dengan produksi awal gas mencapai 2.869 MMscfd

Liquid loading problems occur in the reservoir, below the critical flow
rate the liquid gas will be deposited and clog the perforation holes and
production equipment such as tubing and other equipment. The reason for
choosing capillary string as an artificial lift system is very efficient because the
installation cost is quite cheap, reduces productioncosts, and the installation
process is fast.
Based on the data obtained, the CVD well in the BLP-1 field was installed
with a capillary string measuring 4-1/2 x 3/8 inch at a target depth of 3152
mBRT based on the densest liquid level survey data.
In the CVD well, the surfactant injection rate is set at 153 liters per day
foran initial gas production of 2,869 MMscfd
