Abstract

The unidealized of physical and rheological mud can occured when drilling on rock layers with high salt concentrations. It is therefore necessary to add an additive to balance the effect of the salt. The aims of this study is to see the effect of salt addition on various temperature drilling mud.This research will use two types of mud with different oil-water ratio. The drilling mud will be divided into four compositions, ie LA, LB, LC, and LD. LA and LC compositions have an oil-water ratio of 80% oil and 20% fresh water. While LB and LD compositions have oil-water ratio of 75% oil and 25% fresh water. Then the study was conducted at various temperatures, ie 80 °F, 130 °F, 180 °F, 230 °F, 280 °F, and 330 °F. After observing of the physical properties and rheology of drilling mud, it was found that the effect of adding salt NaCl can improve the physical and rheological properties of mud such as density, viscosity, gel strengh, mud cake, and solid content. Conversely, the effect of adding NaCl salt may reduce the nature of electrical stability. While the increasing of the temperature can reduce the physical and rheological properties of mud and on the contrary the loss of water and mud cake will increase.

Abstract

Currently the waste generated from public consumption in Indonesia is very high. One such waste is used palm oil from households and food companies. Utilization of this waste in this research is by recycling waste oil into surfactants which will be used in the Enhanced Oil Recovery (EOR) process. The surfactant concentrations used were 1.3%, 1.5%, 2%, 2.2% and 2.5%. The research began with refining used cooking oil with banana peels for 24 hours. In order to make surfactants, the oil is mixed with KOH and distilled water. Additionaly, brine was made with a salinity of 15,000 ppm. With the interfacial tension test, a solution with an optimum surfactant concentration of 2.2% was obtained. The core flooding test was carried out using waterflooding followed by surfactant flooding at a temperature of 70 oC. From the test results obtained an incremental oil recovery factor of 8.57% and a total oil recovery factor of 47.43%.
