RINGKASAN
Mayoritas sumur minyak di Lapangan Tanjung merupakan sumur tua
dengan reservoir yang bercirikan tekanan dan temperatur rendah, serta produksi air
tinggi. Karakteristik minyak bumi di Lapangan Tanjung mempunyai kandungan
lilin yang relatif tinggi yaitu sebesar 26,6% berdasarkan hasil uji Pressure Volume
Temperature (PVT Test). Kondisi ini menyebabkan beberapa sumur di Lapangan
Tanjung mengalami kendala dengan terbentuknya endapan lilin dan kerak secara
bersamaan di dalam peralatan lubang sumur. Terjadinya lilin dan kerak secara
bersamaan dapat berdampak signifikan terhadap laju produksi.
Metode yang dipergunakan untuk menghilangkan permasalahan endapan
lilin dan kerak secara bersamaan disebut Wax Scale Removal (WSR). Wax Scale
Removal (WSR) dapat secara efektif mengatasi masalah endapan lilin dan kerak
yang terjadi secara bersamaan pada peralatan produksi. Metode wax scale removal
(WSR) mempergunakan pelarut (xylene-musole) untuk melarutkan endapan lilin
dan asam untuk melarutkan kerak diinjeksikan bersama-sama menggunakan teknik
huff and puff.
Desain Wax Scale Removal (WSR) yang diaplikasikan pada sumur “LTW-
118” telah terbukti effektif untuk memperbaiki produktifitas sumur. Pada penelitian
ini diamati perbandingan lama soaking time yaitu antara soaking time 1 jam dan
soaking time 12 jam berdasarkan hasil uji laboratorium kestabilan emulsi xylene-
musole. Penambahan soaking time pada pekerjaan Wax Scale Removal (WSR) ini
dapat meningkatkan productivity index sumur dari 2,01 menjadi 3,37.
Kata kunci: wax and scale removal, huff and puff, soaking time.

ABSTRACT
The majority of oil wells in the Tanjung Field are old wells with reservoir
characterized by low pressure and temperature, as well as high water production.
The characteristic of oil in the Tanjung Field has a relatively high wax content of
26,6% based on PVT (Pressure Volume Temperature) Test. This condition has led
to several wells in the Tanjung Field experiencing issues with the simultaneous
formation of wax and scale deposits within the wellbore equipment. The
simultaneous occurrence of wax and scale can significantly impact the production
rate.
The method used to eliminate the problem of wax deposits and scale
simultaneously is called Wax Scale Removal (WSR). Wax Scale Removal (WSR)
can effectively solve the problem of wax and scale deposits that occur
simultaneously on production equipment. The Wax Scale Removal (WSR) method
utilizes solvents (xylene-musole) to dissolve wax deposits and acids to dissolve scale
injected together using the huff and puff technique.
The Wax Scale Removal (WSR) design applied to the “LTW-118” well has
proven to be effective in improving well productivity. In this study, a comparison of
soaking time was observed between soaking time of 1 hour and soaking time of 12
hours based on stability test of solvents samples. The addition of soaking time to
the Wax Scale Removal (WSR) job can increase the well productivity index from
2,01 to 3,37.
Keywords: wax and scale removal, huff and puff, soaking time.
