Abstract

Well “X” merupakan salah satu sumur produksi panas bumi yang memproduksikan fluida dua fasa yaitu uap dan brine. Brine inilah yang biasanya membawa zat-zat yang dapat membentuk scale seperti Silica, Calcite dan Sulphide. Scale pada sumur produksi dapat mengurangi produksi secara signifikan karena mampu menghambat aliran fluida di dalam sumur. Hal itulah yang terjadi pada Well “X”. Parameter terpenting dalam pembentukan scale adalah Scale Saturation Index (SSI). Bila SSI > 1, maka fluida dalam kondisi supersaturated dan pengendapan silica dimungkinkan terbentuk. Pembentukan scale akan meningkat seiring dengan penurunan temperatur dan kenaikan pH akibat flashing. Sehingga laju pembentukan scale dan lama waktu pembentukan scale dapat dihitung secara matematis. Data yang diperlukan dalam analisa ini adalah data hasil produksi Well “X” (Output Curve) dan data sampel scale Well “X”. Untuk menghitung SSI dilakukan perbandingan antara konsentrasi silica dalam larutan dengan kelarutan amorphous silica pada kondisi yang sama. Sedang kan untuk menghitung laju pembentukan scale dan lama waktu pembentukan scale adalah densitas silica, kelarutan quartz pada temperatur reservoir, larutan amorf pada temperatur flashing dan salinitas. Dari hasil analisa yang dilakukan didapatkan bahwa endapan silika tidak akan terbentuk pada WHP yang telah digunakan. Apabila dilakukan analisa Trial and Error diantara didapatkan bahwa nilai SSI ? 1 berada pada tekanan 2.3 bar a atau 18.08 psia. fgSedangkan untuk analisa laju dan lama waktu pembentukan scale, pada tekanan WHP 7.81 bar a atau 114.64 psig merupakan yang paling baik karena laju pembentukan scale yang tidak terlalu besar yaitu sekitar 1.56 inch/ tahun dan waktu pembentukan scale sebesar 25% adalah yang lebih lama yaitu 1.12321 tahun.

Abstract

Overhead tool inspection is an important process in the oil and gas well drilling and maintenance industry. In harsh and hazardous environments, it is important to regularly monitor the physical condition and functionality of overhead tools. The use of overhead tools in the oil and gas industry has the advantage of lifting and moving heavy loads easily and safely. However, the use of heavy equipment also carries the risk of dangerous work accidents. The methodology in this research involves problem identification, literature review, research design, data collection, interpretation, analysis, and findings. The discussion emphasizes the meticulous inspection required for overhead tools, exemplified through the evaluation of traveling block, hook block, crown block, elevators, and elevator links. Each inspection, guided by API standards, ensures compliance, identifies potential hazards and prevents incidents in the inspection of overhead tools, various methods are used to ensure accurate inspection results and reduce the risk of failure during operation. This inspection involves techniques such as visual inspection and Non-Destructive Test (NDT) to test each overhead tools component which is guided by API SPEC 8A, API RP 8B and also API SPEC 8C. The main objective is to ensure that every aspect of the overhead tools has been carefully inspected and produces accurate inspection results. Thus, the risk of failure when inspecting overhead tools can be significantly reduced.The results indicate that the overhead tools inspected at PT. BSM meets API SPEC 8C standards. However, crucial findings, such as defects in crown block bearings and elevator safety pin issues, underscore the need for immediate attention. The conclusion emphasizes the importance of swift action to maintain safety and prevent further damage.

Abstract

Indonesia, recognized for possessing substantial geothermal energy potential, is working towards harnessing the resource to achieve numerous objectives. Among the primary challenges encountered is the considerable expense of geothermal drilling. One of the most significant obstacles to achieving this objective is the high drilling cost, which constitutes 35-40% of the total cost of geothermal energy development. The drilling cost is mainly affected by the time needed to drill one well because the faster the time, the lower the cost. Therefore, this research analyzed drilling activities, identified the fastest and most effective methods for optimal geothermal drilling performance, and reduced costs. The research also determined the factors that contributed to the sustained status of Well X as the fastest well drilled in the past decade. The methodology comprised literature review, data collection through adequate background on well and geothermal field, and data analysis. The result showed that the fastest drilling operation of a geothermal well in Indonesia in 2012 occured in West Java (Well X) for only 9.9 days with 1736.5 meters (mMD). Meanwhile, in 2021, Well Y in Sumatra spent 21.74 days to reach a depth of 2200 mMD. The use of a single-run and clean-out Bottom Hole Assembly (BHA) throughout the entire section affected the drilling duration and significantly reduced the inner side cleaning time, respectively. The cost of Well Y drilling, achieved using the best performance of two wells, reduced drilling costs by 19.2%.

Abstract

This study aimed to develop an integrated diagnostic framework to identify pack-off–type stuck pipe during cement drill-out operations and strengthen quantitative risk assessment for workover interventions. A stuck pipe event in the XSF well (9-5/8-in. section) at 724.42 m was investigated using drilling data, drill-string mechanics, drilling fluid evaluation, and hydraulic/cutting-transport analysis. The results of the mechanical assessment showed that excessive loading and overpull were unlikely primary causes of stuck pipe problem. However, the hydraulic and transport evaluation showed inadequate cutting removal, consistent with particle settling and progressive pack-off formation. To evaluate this event, a diagnostic classification matrix combining four operational indicators was applied, showing complete agreement with an established pack-off classification method. The pipe was ultimately freed after 99 hours using controlled tension-cycling with spotting-fluid support. Based on the transport analysis, this study recommended operational controls, which included maintaining a minimum circulation rate of 340 GPM and the use of shale shakers during cement removal to reduce pack-off risk. Furthermore, the prolonged liberation time showed the substantial cost impact of stuck pipe problem, supporting the economic case for preventive implementation.

Abstract

The oil and gas industry is facing increasing pressure to reduce carbon dioxide (CO₂) emissions while maintaining operational efficiency and regulatory compliance. However, conventional cloud-based emissions monitoring systems often suffer from latency, bandwidth limitations, and reduced reliability in remote operational environments. This study aims to explore the role and implementation of edge computing as an enabling technology for real-time CO₂ emissions monitoring in oil and gas facilities. The architecture of the proposed system integrates the Internet of Things (IoT) gas sensors, local data processing units, and cloud platforms for long-term analytics and reporting. The system is designed to process the emissions data closer to the source with the aim of significantly reducing latency, improving measurement reliability, and enhancing responsiveness to abnormal emissions events. The performance was subsequently evaluated through a distributed monitoring test scenario that simulated multiple emissions monitoring points under intermittent network connectivity conditions often experienced in remote oil and gas operations. The focus was on key performance indicators including data latency, bandwidth utilization, and system availability. The results showed that the edge-enabled architecture reduced average data latency from approximately 3.8 s to 0.9 s and data transmission volume by an estimated 79% through local preprocessing while maintaining monitoring availability above 96% during network disruptions. The trend reflected the ability of edge computing to provide a scalable and robust solution for continuous CO₂ emissions monitoring, particularly in geographically distributed and harsh operational environments often associated with oil and gas operations.
