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.

Geothermal energy from the Earth's magma is manufactured in the form of hot steam. On the process of transmission of steam in the Pipe Line, there are various problems such as condensation in the steam. Condensation can cause problems such as pressure drop. The formation of condensate gives a negative impact on production activities both in the pipeline or power plant, thus condensate formed in pipelines should be disposed of via the blow down or steam trap. Due to a large number of steam pipelines in the DW area then to do an analysis of pipelines in order to prioritize the disposal of condensate in the pipe more prone formed condensate. DW Area special analysis was not done against condensation and the number of condensates that are formed so as to indicate the occurrence of condensation done with regular analysis pressure drop in the pipeline. The results of the analysis of the pipeline must first and more frequently carried out disposal of condensate on the RL 014 based on pressure drop highest is line DW 14 a and DW 67, next line DW 18 and 17, and the last is the line 11 and 14 b DW. The condition of the steam trap is also noteworthy if the steam trap leak then it can lower the temperature in the pipe. The drop in temperature in the pipeline will accelerate the condensation, the results of the analysis there is a steam trap leaked is 401.00.17.ST19 and 401.00.05.ST14 . Steam trap leaked that needs to be done to combat the most. The production of steam RL 014 per day was able to donate a 52.52% or about 73.5 MW of the total needs of PLTP (geothermal power plant) 140 MW per day.

In oil, gas, and geothermal drilling activities, the casing cementing process is always carried out in order to fulfill its function properly and safely. Therefore, everything that supports these activities must be carefully thought out. Before the actual cementing process is applied in the oil, gas, and geothermal field, laboratory-scale simulation must first be carried out by conducting experiments and testing several formulations of cement, water mixture, and additives to be used. The author chooses thixotropic additives, besides functioning as an accelerator, thixotropic can also strengthen the cement itself. With a number of experiments, an optimal cement slurry composition formulation will be obtained, in the sense that by using as few additives as possible, the requirements of the physical characteristics will meet the required standards for conditions (temperature and pressure) of the formation in the well to be cemented. All cementing activities are expected to run well, smoothly, and on time.

In drilling operations it is intended to be able to conduct drilling quickly without causing damage to the drilling equipment and be able to produce good quality wells. Failure on the drilling pipe or bottom hole assembly (BHA) ranks results from loading that exceeds the maximum strength limit of the material. In this study, the calculation of the load on the downhole motor, where in the depth of the drill 512 meters failure occurs in the form of broken downhole motor. Based on the analysis conducted, at a depth of 494 meters the value of the hookload has increased quite high at 131.8 klb, while the maximum allowable hookload value is 121 klb, this indicates an overpull of 10.8 klb and based on the calculation of the drag value, a drag is obtained 38.8 klb while the maximum drag value is 28 klb, the difference between the actual drag value and the maximum allowable drag value is 10.8 klb, so it can be concluded that the failure that occurs in BHA # 10 is due to a drag that exceeds the maximum limit of 10.8 klb.

Cement analysis needs to be done on wells that have decreased production and there is additional water production. The longer the well is produced, the water will approach and even reach the perforation zone which results in the water being produced. Several steps must be proposed in knowing and handling water production in wells, in addition to collecting data from wells and reservoirs in full, analysis of problems related to mechanics such as cementing analysis needs to be done to determine the possibility of leakage, microannulus or channeling. The method used is quantitative, by comparing the amount of water production in two wells and its relation to the hydraulic seal formed in the cement. The analysis was carried out on two wells, namely F-3 and F-4. F-3 wells produce large amounts of water, namely 1168 BWPD. This is possible considering the position of this well adjacent to the water zone. And based on the analysis carried out, the hydraulic seal on the F-3 well has not yet been formed making it possible for direct contact between the productive zone and the water zone. Water production in F-4 wells is 35 BWPD. The low water production in these wells can also be assumed due to the formation of hydraulic seals in cementing. Looking at the data above, it can be concluded that without the formation of hydraulic seals on the F-3 wells, secondary cementing needs to be done to close the cementing which is not good so that there is no leakage anymore and there is no communication between the productive zone and the water zone.

Drilling is a costly activity with high risk. Time is a key variable to minimize costs and risks and increase the overall efficiency of drilling activities. An important factor related to the drilling time is the rate of penetration (ROP). The rate of penetration varies widely and is influenced by many factors. In this research, the correlation is derived using Artificial Neural Network (ANN) Model to predict the penetration rate by considering 11 parameters including formation conditions, drilling bit, drilling fluid, and drilling operations to validate the penetration rate data that are obtained from the surrounding wells. Determination of the neural network structure is carried out to obtain the best ANN model. This model produces an equation that can predict the penetration rate of the 'T' field with an error percentage of ± 20%. The existing model is used to optimize the next well drilling activity. Data processing using the ANN method which is relatively fast and precise shows that the application of this method is interesting to discuss and develop.

Evaluation of the drainage area of a well is an effort to obtain success in planning field development. The size of the drain area not only affects the production rate but will also affect the distribution of pressure and saturation as well as the physical properties of the fluid and reservoir rock. Determination of optimum well spacing is important in field development management. This paper presents observations on the effect of the drain area on the production rate, pressure drop, and recovery factor. Simulation of the well model with a cylindrical drain area is used for various sizes of drainage areas. Based on the analysis in this study, it is concluded that the size of the discharge area affects the production rate, recovery factor, and pressure drop. The decrease in pressure affects the release of dissolved gas as indicated by changes in the gas-oil ratio (GOR) curve and the peak of the GOR.
