Abstract

As time goes by, FFS well production has decreased. This then became the background for implementing matrix-type acidification stimulation measures in the relevant fields. The acid used in FFS wells is 15% HCl and 6% HF. Significantly, this acidification process has 3 stages that need to be applied, namely, preflush, mainflush, and postflush. After this stimulation, it is estimated that there will be an increase of 26.5% with an oil price of 50 USD per bbl. After evaluation, it seems clear that there has been an increase in the production rate considering that the two compounds have reacted on a scale as seen in the increase in Q price in the FFS tang well, from 147 BOPD to 200 BOPD. From an economic perspective, we can also see efficiency in the use of equipment because it minimizes many aspects that need to be changed, in other words the production rate increases only with basic capital for certain chemicals. From the evaluation carried out, economic indicators can also be seen which make this research much more economical compared to previous research, where the FFS Well has a gross profit (Gross Revenue) of 8316000 USD. Meanwhile, the net profit obtained reached 3992000 USD. The NPV value with a discount of 11.87% is 477.58 USD, with an IRR of 33,79693377% and a POT of approximately 4.48 years. Keywords: Production rate, FFS well, scale, matrix, acidizing.

Abstract

Oil and gas are important resources that every country must fulfill and Indonesia, despite being a producer, has not been able to meet domestic demand. In field operations, wells do not always produce optimally, so an evaluation and optimization of pump performance is needed to produce optimal production rates. Research on the evaluation of the Sucker Rod Pump at Well M has been carried out by Untoro, E & Saleky, H (2023), obtained the results of the flow rate (Qmax) of 945.403 Bfpd, the current Q of 236.63 Bfpd, pump displacement (v) of 792.091091 Bfpd, and pump volumetric efficiency of 29.87497%. Thus, from the evaluation results, this research will optimize the Sucker Rod Pump, with the aim of obtaining Sucker Rod Pump optimization results to obtain the optimal production rate. Optimization was carried out by changing the pump SPM from 6 SPM to 8 SPM and the pump stroke length from 150 in to 145 in, so that the production rate increased from the previous 236.63 Bfpd to 355,3 Bfpd, and the pump volumetric efficiency increased to 34,77%.

Abstract

Storage tanks, also commonly referred to as storage tanks, are one of the units or pieces of equipment used to store fuel. One industry that uses this equipment is the Namlea PLTD located in Buru Regency. The type used is a Fixed Cone Roof Tank to accommodate fuel that will be supplied to the power plant engine (Diesel Engine). The service life of the tank is ± 5 years, but based on field observations, it appears that there is corrosion on the surface of the tank, which is quite fast. Concerning that, the purpose of this study is to calculate the corrosion rate and corrosion hazard during the general period of use. The method used in data collection is field observation by measuring plate thickness using an Ultrasonic Thickness Gauge. Furthermore, the measurement results were analyzed using the API 563 standard to calculate the corrosion rate. The results showed that the corrosion rate on the tank blanket (shell) at the first level was 0.9 mm/year, the second level was 0.6 mm/year, the third level was 0.88 mm/year, the fourth level was 0.9 mm/year, and the fifth level was 0.85 mm/year. Then the remaining life for shell parts at the first level is 6 years, the second level is 7.6 years, the third level is 7.8 years, the fourth level is 7.9 years, and the fifth level is 9 years. The results of data processing indicate that the 300 KL diesel tank remains feasible for operation in Namlea PLTD, Buru Regency. Keywords: Fixed Cone Roof Tank, standard, thickness, corrosion rate

Abstract

In oil and gas industry activities, the oil and gas processing process will produce waste, one of which is oil solid waste, which is waste that comes from the production and processing process of petroleum in the oil field because it is one of the supports for the Cepu refinery which has several old wells that are still actively producing to this day, thus the use of waste oil is very necessary. With the amount of TPH obtained from waste oil, which is 48.10%, there is potential to be extracted. The method used is a simple heating method to separate hydrocarbons from waste solids. After the extraction test was carried out and associated with the results of the oil composition test, the saturated composition was obtained 48.84%, aromatic 23.59%, resin 25.91% and asphaltene 1.66% where this composition has an influence on the results of the hydrocarbon extraction test from waste oil. With simple heating using an oven, the results obtained are not significant as the extracted oil hardens again. After heating, the light fraction of saturated oil is released while the heavy fraction, resin and aromatics, as well as impurities, affect the hardening of the sample at room temperature.

Abstract

Workover and well service activities are routine activities to repair and maintain production wells, such as replacing oil pump equipment and changing well hole reservoir parameters such as drilling and cracking activities This is done to repair and maintain wells so that they can always produce according to the specified potential However, during the work, the production of each well that requires repair must be temporarily stopped until the well is repaired. The length of time a well is not producing depends on the length of the repair of the well. Therefore, drilling performance must be evaluated to avoid delays in well production in the long term. Based on the results of this study, the PDSI# 35.1/IDECO H-35-M rig has a performance level of 88% for 15 days; the performance presentation of the rig is good. In addition, from the results of the NPT using a Pareto diagram, there are several main problems that cause rig performance, namely, waiting for a bright day, waiting for equipment repair time, inspection/safety checklist, and waiting for licensing time.Keywords: Rig Operational Performance.

Abstract

The effect of additives such as seashells (containing CaCO₃) and nani wood charcoal on the mechanical properties of steel during the carburizing process is significant. The addition of CaCO₃ acts as a catalyst, accelerating carbon diffusion into the steel's microstructure, thereby increasing surface hardness and flexural strength. The results showed that increasing the percentage of CaCO₃ up to a certain point can increase the hardness and strength of the steel, with the highest hardness value achieved at a variation of 50% CaCO₃ and 50% nani wood charcoal, at approximately 21.93 HRC. Hardness testing showed that the variation of additives directly affected the final hardness, with the highest value being achieved at the optimal combination of CaCO₃ and nani wood charcoal. In addition to hardness, other mechanical properties, such as bending strength, also showed an increasing trend with increasing CaCO₃ proportions up to the optimal point, namely at a variation of 70% CaCO₃ and 30% nani wood charcoal, which resulted in a bending stress of 32.64 MPa and a bending strength of 3336.14 MPa. Therefore, the adjustment of the proportion of additives is a key factor in optimizing the mechanical properties of steel through the carburizing process enriched with these natural materials. Keywords: seashells, nani wood charcoal, catalyst, a bending strength

Abstract

This study aims to analyze the effect of varying paint and thinner mixtures and the number of coats applied on the adhesion and hardness of car paint. The research method used was experimental, varying the paint:thinner ratio (100:110, 100:120, 100:130, and 100:140) and the number of coats applied (2 and 3). Adhesion testing was performed using a Cross-Cut Adhesion Tester, while hardness testing was performed using a Shore D Durometer. The results showed that a paint:thinner ratio of 100:130 provided optimal results for both tested parameters. In the adhesion test, the 100:130 ratio achieved level 5B (best) with no paint peeling, while in the hardness test, it reached the highest value of 88.77 HD. Excessive addition of thinner (ratio 100:140) resulted in a decrease in quality, with adhesion decreasing to level 3B and hardness dropping to 83.3 HD. Variations in the number of coats showed that using two coats provided more consistent results than three coats, especially in terms of adhesion. This study concluded that an optimal balance between paint and thinner is crucial for achieving good paint quality, with a 100:130 ratio providing the best results for automotive body painting applications.

Abstract

Automatic motorcycles are a type of motorcycle equipped with an automatic transmission system that does not require a manual gear lever for shifting. The gear ratio changes automatically according to the engine speed, allowing the rider to control acceleration solely by adjusting the throttle. The use of an automatic transmission, or Continuous Variable Transmission (CVT), in this system relies on a standard V-belt, as it significantly affects engine performance. However, some motorcycle owners use non-standard belts because they are cheaper, which often leads to faster wear. This study was conducted to determine the wear rate experienced by both standard and non-standard belts after a certain period of use under specific operating conditions. The method used to evaluate belt wear rated an experimental approach, in which the motorcycle was operated at an average speed of 40 km/h over a distance of 24 km for three hours per day, over a period of three months (12 weeks). Each week consisted of 5 days of testing, with the first 6 weeks allocated for the standard belt and the following 6 weeks for the non-standard belt. After the testing period, the belts were removed and their wear was measured. The measurements were compared to the initial data to determine the amount of wear that had occurred. The results showed that the standard belt, after 6 weeks of use (90 hours), experienced wear of: 0.10 mm in diameter, 0.72 mm in upper width, and 0.25 mm in lower width. Meanwhile, the non-standard belt exhibited wear of 0.31 mm in diameter, 0.92 mm in upper width, and 0.78 mm in lower width. Based on these findings, using a standard belt is preferable, as it does not wear as quickly as a non-standard belt. Keywords: automatic motorcycle, V-belt, wear rated.
