Abstract

There are three levels in producing oil or natural gas: primary recovery where oil flows into the wellbore by itself; secondary recovery where oil flows with the help of water or gas injection; and tertiary recovery, commonly called Enhance Oil Recovery (EOR). Total recovery from one oil field is about 50% -60% of OOIP. With primary and secondary recovery 30% -40% can be obtained from OOIP, it is expected that the remaining 20% -30% can be taken with EOR. This study investigated EOR by injection of various surfactant concentrations at temperatures of 30°C and 80°C using brine with salinity of 10,000 ppm by imbibition. The aim of this research is to know the effect of surfactant concentration and salinity of the formation water on oil acquisition in relation to sandstone permeability, and to find out what level of concentration to the average permeability rate with temperature close to reservoir average temperature (80°C), can be obtained a minimal Sor so that RF (Recovery Factor) to be maximal. The methodology used is to measure: the physical properties of rocks and fluids (the solution used), the interface voltage and selected the best solution (the smallest interface voltage), and soaking the rock with Amot test glass. From this study, it can be concluded that the addition of concentration will decrease the density, but the addition of temperature will decrease the density and viscosity; the addition of the surfactant and temperature concentration will decrease the interface voltage until the CMC point is reached; good permeability and porosity may not produce good results when clay contamination is present

Abstract

Completion fluid is a fluid used in conducting operational completion, where the fluid used must be based on consideration of the formation characteristics for a particular well. Fluid selection is very important if the formation damage will be minimized. good complexion fluids can reduce solid content, absence of clay, solulable acid, dissolve in water and are used for operations such as perforation, cleaning wells and well control. The nitrate salts used are CaNO3 and NaNO3 salts. Agarfluida complexes can function properly, so the fluid must always be controlled for its physical properties, which consist of fluid specific gravity, fluid rhology, filter rate, swell meter and pH. The use of compound fluid is adjusted to the conditions of the formation that is being perforated such as formation rock formation conditions, and fluid content contained in the formation. This study will examine the use of fluid complexes from heavy salts of nitrates as hole cleaning and their effect on the additives used. It was concluded that the use of saline-complex fluid heavy with NaNO3 nitrate and its combination with the use of CaCO 3 had the effectiveness to carry out hole cleaning activities with the results of Plastic Viscosity 23 cp, 24 lbs / 100 ft Yield Point, 4.2 ml / 30 'Filtrate, pH 7, 41, and Swellmeter 6%.

Abstract

The distribution system is one of the most important elements to be able to distribute electrical energy from power plants to consumers. Tanjung Balai Karimun, Kepulauan Riau is an island near the island of Batam. PT Karimun Power Plant has built a plant with a total capacity of 7.5 MW consisting of 5 machines with a capacity of 1.5 MW each. This research is aimed at the appropriate distribution system to be applied there. Medium voltage air duct is one of the existing systems, and is suitable to be applied in Zone II Tanjung Balai Karimun Riau Islands. The cross section size used in the calculated conduit is 100 mm² in the upstream and 16 mm² in the downstream. These conveyors are supported by a pole with a height of 12 m and with a distance between the poles as wide as 100 m. in this system there is also a transformer with a capacity of 160-4000 kVA. This system was tested using ETAP software and produced data that the available generator was not enough to carry the burden in Zone II Tanjung Balai Karimun. Due to inadequate power generation, the long-term solution is to increase the number of plants while the short-term solution is to reduce the burden to be carried.Keywords.
