The alternative solutions of bagasse to improve Indonesian oil production in low salinity

Abstract

Indonesia is one of the largest sugarcane producing countries in the world. At present, the use of bagasse is only as compost, electricity generation, etc. In the oil industry, bagasse can use as a base material in making surfactants that function as fluid reservoir oil injection to improve oil recovery factors, so it is good to develop a type of plant-based local surfactant with a lot of raw materials in Indonesia. The purpose of this study was to see that bagasse can increase the oil recovery factor at low salinity. The methods used is a laboratory study using a concentration of 1%; 1.5%; 2%; 2.5% and 3% NaLS and salinity of 4000 ppm, 5000 ppm, and 15000 ppm NaCl. The Surfactant first conducted a compatibility test then core flooding was carried out to obtain the recovery factor value. The results obtained were surfactants with variations of 1.5% 4000 ppm; 1.0% 15000 ppm; and 1.5% 15000 ppm which passes the compatibility test with the recovery factor value sequentially is 3.24%; 3.62%; and 5.34%. It shows that NaLS surfactant can increase the oil recovery factor at low salinity by 5.34% by optimizing 1.5% NaLS 15000 ppm concentration.

Middle Phase Behavior of SLS Surfactant Bagasse at Intermediate Crude Oil

“…One of the compatibility tests that will be used is the phase behavior test. Phase Behavior is carried out to determine whether SLS surfactant forms a middle phase emulsion when used in a crude oil [2][3][4][5]. In order to be used optimally, surfactants require the right conditions and concentrations.…”
