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

In designing and producing a salt spray chamber test apparatus for the required parameters to be standardized for the test method, the tool is designed and manufactured according to ASTM B117-09 standards, in addition to the standards mentioned, the design of this corrosion test apparatus also refers by studying ISO standards and JIS in the manufacture of such tools. By making this tool is expected to be able to test a specimen of a steel material. In addition to testing, heat transfer calculations and analysis in the chamber area are needed to determine the heat lost and the required power heater. From the result of spray salt collecting test obtained 1.5 ml salt solution in collecting cup with wide of within 1 hour done in two positions, so for equalization of salt fog is in accordance with standard ASTM B117 collecting salt spray 1-2 ml / hr. The next parameter is that the temperature of the chamber must be maintained at 35°±2℃ from the temperature test results in accordance with ASTM B117 standard. From the test result of plate material JIS G 3141 SPCC (Steel Plate Cold Rolled Coiled) dimension 76 x 127 x 0.7 mm for 48 hours with test method. Neutral salt spray result from corrosion rate calculation got corrosion rate equal to 27.4665 mpy.

Creating a magnet with powder metallurgy technology, the materials to be processed must be available in powder form with a relatively very fine size, in micrometers (μm). In the magnetism of materials, grinding the material to obtain a very fine powder size is intended to obtain a magnetic material powder having a single domain. One tool commonly used to reduce the size of the powder to reach the size of a micrometer (μm) is a ball milling machine. This tool works by using hard balls in a drum. The balls are clashing each other with ground powder until the powder size becomes very small. Ball milling is using a strong material SS400, so it is expected to last long. While the special drum uses a base material of metal that is non-magnetic based Austenitic Manganese Steel. Ball uses a Ni-Hard ball. The AC motor measured with a stroboscope while carrying the load is 744 rpm. The process of smoothing that occurs inside the tube when the machine is run is the occurrence of collisions between Ni-Hard balls with the best grind sand is 83.3 grams with the number of Ni-Hard ball 101 fruit with a diameter of 10 mm and 75 pieces with a diameter of 11 mm, with using a 1:5 ratio. The process of shooting using Keyence optical microscope VHX 5000 with 200x bundle. Significant size changes occur with grinding with 10 mm diameter Ni-Hard ball from 15 minutes to 45 minutes. Then by using a Ni-Hard ball diameter of 11 mm also changed although not too significant.

The impact test is a test to measure the material's durabilityagainst shock loads. The impact test simulates the operating conditions of that materialoften found where the load does not always occur slowly but rathercame suddenly. The impact test instrument to be designed in this studyis a Drop Weight Tester (DWT) tool. This impact test apparatus utilizes massobjects and gravitational forces. Design of Drop Weight Tester (DWT) tool, designthe design refers to the ASTM D-5420-04 standard. In this study the designthe impact test apparatus analyzed the strength of the connection as well as the construction deflection forensure design results can be made. On testing Drop Weight Tester, objectsthe test is given a shock load with certain criteria such as altitude, load, dimensionpunch component striker as well as specimen thickness. At the same time it is doneobservation and data collection of the energy absorbed during the test.Specimen used is SPCC and Zincalume material with thicknessdifferent.

Polymer injection is one of the methods of increasing oil recovery or Enhanced Oil Recovery (EOR) after the water injection method is performed, to reduce residual oil saturation. The polymer reduces the water mobility ratio so that the sweeping efficiency will increase to encourage bypassed and unswept residual oil saturation. For polymer injection applications, partially hydrolyzed polyacrylamide (PHPA) or commercially known as HPAM is the most widely used type. At the current low oil prices, design optimization of polymer injections in certain reservoirs is important. The purpose of this research is to analyze the effect of permeability and polymer concentration on residual oil saturation by core flooding method in the effort of optimization of polymer injection. The optimal concentration in this study is 1,500 ppm which has the lowest residual oil saturation value. The increase in concentration from 500 ppm to 1.500 ppm, residual oil saturation decreased in four variations of Berea sandstone permeabilities. However, when the polymer concentration is added to 2.500 ppm, the residual oil saturation value increases. This can be caused by pore clogging. Whereas with permeability, residual oil saturation is directly proportional. The greater the permeability the greater the value of residual oil saturation. Core Y7 Berea has the highest permeability and saturation of residual oil. The results of this study are expected to be useful in the development of polymer injections on EOR activity.Keywords. polymer injection, concentration, permeability, PHPA, residual oil saturation

A system can be subjected to excessive vibration if the force acting on it approaches the natural frequency of the system. The way to do it, especially for single operating frequency, is adding the dynamic vibration absorber. Generally, the dynamic vibration absorber is a mass-spring-damper addition to the main system. This study researches the effects comparison of Without Dynamic Vibration Absorber and Series Double Dynamic Vibration Absorber on the main system response. Electric motor with unbalanced masses is used as the exciter and placed on the two beams. The main mass is supported by these beams. This system has the specified dynamic equations. The main system response absorber TDVA addition gives 0.008291meter displacement rms at 1, 002 frequency-ratio. The one with DDVA system response absorber with Ma1=1/20 and Ma2 =1/20, Ma1=2/30 and Ma2 =1/30, and Ma1=1/40 and Ma2 =1/40 gives 0.001484 meter, 0.002691 meter, and 0.001343 meter. The system with SDVA gives better response than DDVA. The first absorber mass ability to reduce main mass response is disturbed by the second absorber mass existence.
