Abstract

Indonesia’s total energy supply increased nearly 60% from 2000 to 2021. However, the total energy sector emissions have grown faster than energy demand, more than doubling over the last two decades. In 2021, energy sector emissions were around 600 million tonnes of carbon dioxide (Mt CO₂) – making Indonesia the world’s ninth-largest emitter. Indonesia faces a big challenge with the target to reach net zero emissions by 2060. Carbon capture and storage (CCS) is considered as a potential solution. However, CO₂ injection wells face well integrity issues that may lead to leakage. One of the most common problems in CO₂ injection wells is corrosion. Corrosion may cause damage on the downhole equipment which leads to degradation of the well integrity. Therefore, a thorough material selection should be considered. This study examines critical factors in designing CO₂ injector wells for a CCS campaign in Field "X", a major offshore gas condensate field with a planned injection rate of 160.2 MMSCFD. This study aims to determine suitable casing schemes, tubular material selection, and corrosion analysis for CO₂ injector wells, while evaluating leakage potential based on well barrier concepts. The drilling of “X” field CO₂ injection wells is planned to be executed with an estimated five casing sections consists of 30” conductor casing, 20” surface casing, 13-3/8” intermediate casing, 9-5/8” intermediate liner and 7” production liner. Based on the analysis using ECE (Electronic Corrosion Engineer) software, ISO 15156-3 standard, and the Nippon steel chart, the most suitable tubular materials for the CO₂ injector well is Duplex Stainless Steel SM22Cr or SM25CR.

Abstract

Carbon capture and storage (CCS) is widely recognized as a significant technology in mitigating carbon dioxide (CO2) emissions from major industrial facilities, such as power plants and refineries. CCS involves the capture of concentrated CO2 streams from point sources, followed by subsequent safe and secure storage in appropriate geological reservoirs. We developed spatial database system using Geographic Information System (GIS) tools to facilitate source-sink matching between CO2 emitter and CO2 storage to foster the implementation of CCS/CCUS technologies in Indonesia. In this study, we proposed workflow approach to determine the location of CO2 sinks/storage candidates given limited data available. Additionally, this method spatially characterizes and represents probable clusters where opportunities for CCS/CCUS implementation are present. We consider the existing pipeline route and Right of Ways (ROW) to minimize the potential cost related to transportation of CO2 using pipeline. The priority of available storage is classified based on the storage capacity, distance, and other technical criteria to determine the optimal location of potential CO2 injection. We applied the workflow to Coal Fired Power Plant in West Java as the CO2 source, and we obtained 6 depleted fields that are connected to the existing ROW with CO2 storage capacity of 42.03 MMT.

Abstract

The decreased oil production due to scaling in production equipment results in costs. In oil wells, ions such as calcium, barium, carbonate, sulfate, magnesium, sodium, and chloride are commonly present in formation water. Excessive solubility of ions can trigger precipitation or what is often called scale. This study focuses on creating synthetic brine with a composition resembling field formation water as an alternative solution for rapid laboratory-scale measurement of the scale index. In this study focus on carbonate and bicarbonate scale. The stages of the research involves synthetic brine preparation, physical and chemical testing of the brine, comparison with formation water, and calculation of the Stability Index (SI) using Stiff & Davis method. The results indicate that synthetic brine can be prepared based on laboratory analysis of field samples by estimating the materials and masses present in formation water, thus allowing replication using natural or chemical materials in the laboratory while considering parameters such as pressure, temperature, and pH during the manufacturing process. The pH significantly impacts the risk of scale formation, where a slightly basic pH, around pH 8, supports higher concentrations of carbonate ions (CO32-) and bicarbonate ions (HCO3-), thereby increasing the risk of scale formation.

Abstract

The provenance sediments have been analyzed to reveal tectonic development during the Semilir Formation deposition in the Southern Mountain of Yogyakarta area, using essential samples from field observation, petrography analysis, and the point counting method. Outcrop and sampling at two observation points revealed distinct lithological features, including sandstone and siltstone with mudclast structures and slump structures interbedded with siderite. Petrographic analysis using the point-counting method determined the mineral composition of four samples: 1A, 1B, 2A, and 2B. Samples 1A and 1B were categorized as Lithic Wacke, 2A Feldspathic Wacke, and 2B Lithic Wacke. Provenance analysis, crucial for understanding the sedimentary history and reconstructing the geological events preceding sediment deposition, identified that the sandstones in the Ngoro-oro region predominantly fall into the magmatic arc category. Hence, based on our analysis, the tectonic development during Semilir Fm deposition is linked with the convergence event of the first subduction on southern Java, which had huge volcanic influences and slope morphology common in volcanic areas. The findings of this study contribute to a deeper understanding of the tectonosedimentary processes and geological history of the Ngoro-oro region. The integrated approach of petrographic and provenance analyses provides a comprehensive view of the sedimentary rocks formation and evolution, enriching the geological knowledge of the area.

Abstract

The texture of sedimentary rocks is a fundamental aspect of sedimentation, reflecting the physical properties of particles and their relationships. Understanding rock texture is essential for interpreting depositional mechanisms and environments. Grain maturity represents a key property within sedimentary textures. The Early Miocene Semilir Formation is characterized by turbidite deposits with tuffaceous lithologies; however, the transport mechanism remains unclear. This study aimed to analyze the sedimentation process of the Semilir Formation by observing grain maturity. Granulometric analysis was conducted on three rock samples from the Ngoro-oro area, Gunungkidul Regency, Yogyakarta. The samples were ground, separated into size fractions, and statistically evaluated to determine quartiles, median diameter, sorting coefficient, skewness, and kurtosis. The results showed that the Semilir Formation consisted of immature grain sedimentary rocks, indicating that the sediments were deposited under moderate to high energy conditions. These findings suggest that the deposits were derived from a nearby source and were strongly influenced by volcanic slopes and underwater volcanic activity.Keywords: Grain maturity; Granulometric analysis; Sedimentary process; Semilir Formation
