Lapangan tua cekungan Sumatera Selatan mempunyai tatanan reservoir secara geologi yang cukup rumit dan terjadinya penurunan produksi minyak. Peluang pencarian lapangan eksplorasi dan pengembangan sumur yang semakin sulit merupakan masalah lain yang dihadapi saat ini. Oleh karena itu diperlukan usahan-usaha untuk mempertahankan dan meningkatkan laju produksi dari lapangan minyak yang telah ada dengan cara penambahan sumur–sumur pengembangan. Cadangan Hidrokarbon pada lapisan tiga (L-3) lapangan “HAFUZA” masih besar dan belum tereksploitasi secara maksimal. Untuk mengoptimalkan produksi Hidrokarbon pada lapisan tiga (L-3) diperlukan kajian yang mendalam mengenai geologi, geofisik dan reservoir. Metodologi yang digunakan pada penelitian ini adalah dengan melakukan pengolahan data real lapangan “HAFUZA”. Hal pertama yang dilakukan adalah persiapan data. Persiapan data yaitu data geofisik (seismik, struktur interpretasi), data geologi (log, korelasi sumur, petrofisik), data reservoir dan parameter pendukung lainnya. Kemudian dilakukan pengolahan data-data tersebut yang menghasilkan interpretasi lithofasies (model lithofacies) dan analisa petrofisik. Hasil analisa lithofasies dan petrofisik ini diharapkan dapat digunakan sebagai arah pengembangan sumur lapangan “HAFUZA” sehingga eksploitasi cadangan hidrokarbon pada lapisan tiga (L-3) dapat meningkat.The old field in the South Sumatra basin has a geologically complex reservoir structure and a decline in oil production. Opportunities to search for exploration fields and development of increasingly difficult wells are another problem currently faced. Therefore efforts are needed to maintain and increase the rate of production of existing oil fields by adding development wells. Hydrocarbon reserves in layer 3 (L-3) of the "HAFUZA" field are still large and have not been fully exploited. To optimize the production of hydrocarbons in the third layer (L-3), an in-depth study of geology, geophysics and reservoirs is needed. The methodology used in this research is to do real field data processing "HAFUZA". The first thing to do is prepare the data. Data preparation is geophysical data (seismic, interpretation structure), geological data (log, well correlation, petrophysical), reservoir data and other supporting parameters. Then the data is processed to produce lithofacies interpretation (lithofacies model) and petrophysical analysis. The results of lithofacies and petrophysical analysis are expected to be used as the direction of the development of the "HAFUZA" field well so that exploitation of hydrocarbon reserves in the third layer (L-3) can be increased.

Permasalahan korosi dapat mengakibatkan bertambahnya potensi pencemaran oleh minyak bumi terhadap lingkungan akibat adanya kegiatan eksplorasi dan eksploitasi. Perawatan peralatan yang tidak tepat, salah satunya gagal memantau kelelahan logam dan korosi, dapat menyebabkan kecelakaan fatal pada industri migas. Penelitian ini bertujuan untuk mengetahui laju korosi pada baja karbon rendah yang disambung dengan pengelasan dan telah diberikan perlakuan panas pasca pengelasan. Untuk mengetahui laju korosi pada hasil las baja karbon rendah dilakukan pengujian menggunakan media air laut. Metode penelitian dimana spesimen baja karbon rendah yang sudah dilas dengan las listrik, kemudian dilakukan pemanas atau heat treatment dengan dipanasi lagi sampai temperatur 300 oC. Spesimen dilakukan penimbangan dengan ketelitian 0,01 gram dan pengukuran dimensi dengan ketelitian 0,001 mm, kemudian dimasukkan dalam air laut yang sudah diletakkan dalam wadah berupa gelas plastik tanpa penutup. Spesimen direndam untuk 100 jam, 200 jam, 300 jam dan 400 jam. Hasil pengujian berat dan penurunan berat spesimen, diperoleh berat rata-rata tertinggi spesimen yaitu pada rendaman 100 jam, didapat berat rata-rata sebesar 9,641 gr dengan selisih berat 0,016 gr. Sedangkan berat rata-rata terendah spesimen yaitu pada rendaman 400 jam, didapat penurunan berat rata-rata sebesar 9,575 gr dengan selisih berat 0,020 gr. Hasil pengujian dimensi dan luas permukaan terendam, diperoleh hasil dimensi rata-rata tertinggi pada rendaman selama 100 jam sebesar 2.031,312 mm2 dan dimensi rata-rata terendah diperolah pada rendaman 400 jam yaitu sebesar 2.009,594 mm2 . Berdasarkan data penurunan berat spesimen dan penurunan dimensi, diperoleh hasil perhitungan laju korosi/corrosion rate (CR) sebesar 0,088 mpy untuk lama perendaman 100 jam. Untuk perendaman selama 200 jam dengan menggunakan data yang sama, diperoleh laju korosi/corrosion rate (CR) sebesar 0,106 mpy. Sedangkan untuk perendaman selama 300 jam dan 400 jam, diperoleh laju korosi/corrosion rate sebesar 0,114 mpy. Berdasarkan grafik laju korosi terhadap waktu perendaman menunjukkan semakin lama waktu rendaman, semakin tinggi laju korosinya.

The world oil and gas market has experienced uncertainty since 2014 until now. Fluctuating supply and demand, geopolitical tensions, and shifts in energy policies cause this. In addition, at the beginning of 2020, there was a prolonged pandemic, which made oil and gas conditions even more erratic. This uncertainty significantly impacts the Indonesian state, especially the Indonesian government and oil and gas companies operating in Indonesia. Various methods have been taken to mitigate the impact of this uncertainty, both by the government and oil and gas companies. Therefore, this study aims to conduct a literature review regarding the strategies undertaken by the Indonesian government and oil and gas companies in Indonesia to address the uncertainty in world oil prices since 2018. This research was conducted using the literature method. A review of scientific articles that have been published from 2018 to 2022. The selected articles follow the research objectives and comply with the inclusion and exclusion criteria set at the outset. Results of the literature process the review obtained as many as 67 articles that discussed various strategies carried out by the government and oil and gas companies. The discussion results show three strategies carried out by oil and gas companies in Indonesia: cutting costs, implementing digitalization, and diversifying into renewable energy projects. Meanwhile, the strategy undertaken by the Indonesian government includes providing fiscal incentives, investing in infrastructure that supports the oil and gas sector, deregulating the oil and gas sector, and encouraging the use of renewable energy as an alternative energy source. These various strategies aim to increase efficiency, reduce costs, diversify energy sources, and increase competitiveness in Indonesia's oil and gas sector to deal with the uncertainty of world oil prices.

The Betung Field is one of the oil and gas fields located in the Jambi Sub-Basin, South Sumatra Basin with the target of the Air Benakat Formation sandstone reservoir. The cut off value is determined based on the character of the reservoir to eliminate non-contributing rock volumes. Economically, the cut-off value of oil production can be calculated by oil prices and budgeted total costs. There are 4 layers (L-2, L-3, L-4 and L-5), where Layer 5 (L-5) is the research focus in the cut-off determination method. The methodology in this cut-off study used qualitative and quantitative analysis in three (3) wells out of ten (10) wells L-5 in the Betung Field. The primary data used are well logs, production data and economic data. The well log data is processed to obtain the petrophysical value of the wells. The petrophysical results will be analyzed and the cut-off will be determined for each well and layer in L-5. Production and economic data are processed to obtain cut-off clay content (Vclay) which aims to strengthen the cut-off results from petrophysical yields. Based on the results of calculations and analysis, layer five (1-5), the Betung Field has a cut-off clay content (Vclay) < 34.2%; porosity > 15.8%, water saturation < 83.3%.

Cumulative fluid production during 2009 - 2021 in the Betung Field, which is the research location and is located in the Jambi sub-basin-South Sumatra Basin (Barber et al., 2005), amounted to 277,923.52 MBbl. The relationship between porosity and permeability can be said in general that if the porosity is greater, the permeability will be greater, but in reality it will be found that certain layers will have large porosity but small permeability, such as in layers containing clay or shale. Mineralogical composition plays an important role, especially with regard to clays, involving several compositions including illite, smectite, kaolinite and chlorite. The presence of quartz and feldspar increases permeability, while clay minerals and calcite tend to have the opposite effect (Jose M. Carcione et al., 2019). The analysis carried out included XRD analysis to determine the mineral composition of the reservoir sandstone of the Airbenakat formation, rock quality analysis (porosity and permeability), well log analysis and then the overall analysis results were linked to production data. Based on XRD analysis, petrophysical analysis of wells 209 and 217 in the Betung field, Airbenakat formation, Jambi sub-basin, South Sumatra basin, the results of XRD and petrophysical analysis show the presence of clay content consisting of Kaolinite, Illite, Smectite and Chlorite which has an influence on reservoir quality, especially permeability, where the greater the clay content, the more obstructed fluid flow is.
