Mud is one of the things that is very supportive in drilling operations, the design of the mud can affect the effectiveness of drilling work, the costs to be incurred, up to when the well is in production. Of course what is expected from a mud usage is low expenditure and drilling with optimal results. Drilling mud plays a very important role in a drilling operation. Drilling that can run quickly, safely and economically is greatly influenced by the conditions and sludge system used. The condition referred to here is how the properties or rheology of the mud. Whereas the mud system referred to here is a certain type of mud that must be used with regard to the state of the formation and borehole. Muddy KCl-POLYMER is a non-dispersed mud, where the hydration and dispersion process of the shale formation drilled must be maintained or maintained as much as possible. There are several ways to achieve this, the most common of which is to limit the amount of water that reacts with the shale, by covering the cutting produced by the shale with the polymer as soon as possible to prevent further reactions with water. In this study, we will analyze the use and physical properties of drilling mud using KCl-Polymer sludge which is carried out in the Trisakti University Laboratory of Petroleum Drilling and Production.

<em>In the process of drilling and servicing oil wells, KCl and NaCl used to provide hydrostatic pressure into the bowels of the earth. The brine solution was produced accidentally to the surface facility when the oil lifting process was carried out and induces the thickness of the oil-water emulsion in the separation tank. Emulsions must be broken down into oil and water phases so that they do not interact with the oil treatment process in the refinery unit. Emulsion stability was influenced by pH, salinity, temperature and concentration of asphaltene, resin and wax. The purpose of this study was to determine the effect of salinity on the oil-water demulsification process. This research was conducted by varying the salinity of 5%, 15%, 25%, and 35% in a 100 ml oil-water emulsion sample with a ratio of 1: 1 oil and water. Demulsification of the emulsion sample using the precipitation method for 120 minutes by recording the% of oil volume separate every 20 minutes, at temperatures of 30 ° C and 110 ° C. The higher the temperature given, the more stable the emulsion in crude oil. From the final result after 120 minutes of pricipitation shows that the emulsion separation process which influenced by NaCl salinity is more difficult than the effect of KCl salinity.</em>

<em>In the world of oil is very common in the production system. This production system produces oil from wells after drilling and well compressions. Over time, the production of a well may decrease due to several parameters of pressure drop and the presence of clay which makes the pipe diameter narrower. There are several methods used to increase the decrease in production including adding artificial lifts such as sucker rod pump, electric submersible pump and gas lift, reservoir stimulation and pipe cleaning if the pipe diameter is reduced due to clay. The well has been installed an artificial lift is a gas lift and this well need an optimization to increase its production. The EC-6 well optimization is planned by comparing the lift-up scenario of the gas lift by adjusting the rate of gas injection and deepening the orifice injection and also an installation of electrical submersible pump. Best percentage of optimization production from EC-6 Well, last scenario is chosen which is new installation artificial lift ESP from gas lift (existing) and gaining 18.52% form existing production</em>

Oil-water emulsion formation is common in oil fields. The emulsion is a problem which causes an increase in production costs and a decrease in oil quality. Therefore, a demulsifier formulation is needed to overcome these problems. The use of household waste, particularly disposable diapers, is a promising alternative. One of the substances contained in diapers is sodium polyacrylate super absorbent polymer, known as sodium polyacrylate. The substance takes 450 years and 500 years to decompose in the sea and on land. Sodium polyacrylate has inert and hydrophilic properties with the working principle of absorbing and trapping water which is expected to reduce the water content in oil-water emulsions which are mostly produced from old oil wells. In this experiment, diapers were used to separate the emulsion in light crude oil samples which were tested with brine with 20% and 70% salinity at 50oC. Centrifuge was used to speed up the demulsification process within 1 to 3 minutes. It can be concluded that sodium polyacrylate contained in diaper waste can reduce the water content of the emulsion. In addition, the demulsification process by sodium polyacrylae was more stable and higher in brine with a salinity of 70% compared to brine with a salinity of 20%.

<p>Volume limbah plastik yang semakin banyak, serta semakin mahal dan langkanya bahan bakar rumah tangga menjadi tantangan peneliti dalam mencari energi baru dan terbarukan sekaligus memanfaatkan barang – barang yang dianggap limbah menjadi barang yang bisa memiliki pengganti energi alternatif, sehingga dapat membantu masyarakat dalam mengoptimalkan ekonomi keluarga. Kegiatan PKM ini bertujuan untuk memberikan penyuluhan dan pelatihan kepada masyarakat agar dapat memanfaatkan limbah plastik yang tidak dimanfaatkan untuk menjadi bahan bakar alternatif yang dapat dimanfaatkan masyarakat sebagai bahan bakar di rumah tangga. Sehingga dapat membantu masyarakat dalam pengeluaran pembeliaan gas maupun minyak tanah sebagai bahan bakar dalam memasak maupun bahan bakar kendaraan.</p>
