Abstract

The well KWG-PXX in the Cepu Field is an oil well that uses the artificial lift production method namely Sucker Rod Pump (SRP). It has sand problems during production. Sand control with a sand pump (bailer) is a passive approach that can be applied with small sand production and well maintenance is economically feasible. The sand bailing out method with a sand pump is a process of removing the sand contained in the well, well formation, and casing. This pump is a barrel connected to tubing and inserted into the wellbore using tubing or wireline. Based on calculations, it was found that the sand pump capacity required to clean the wellbore from sand to open perforations was 7641.12 cm3 or 7.64 L. After the well service was carried out, there was an increase in the Productivity Index (PI), from 0.49 bpd/psi to 0.65 bpd/psi. The production rate increased from 389.41 bfpd to 504,824 bfpd. So technically, overcoming the sand problem with a sand pump can be said to be successful because the well can be produced again.
