Abstract

Lapangan “Y” terletak 40 km ke arah Barat Laut dari Pulau Tarakan, Kalimantan Utara memiliki sumur gas “X” yang dalam uji produksinya dilakukan dari secara commingle. Maka harus dilakukan analisis uji sumur untuk mengetahui kemampuannya dalam memproduksikan gas tersebut (gas deliverability). Metode yang digunakan antara lain Modified Isochronal Tets (konvensional), Metode Laminer-Inertia-Turbulen (LIT) dan Metode Jones-Blount- and Glaze. Perbandingan ini dilakukan untuk mengetahui metode mana yang paling optimum dengan juga laju alir yang terbaik. Parameter yang didapatkan dari hasil uji sumur tersebut kemudian dianalisis sebagai data repesentatif untuk digunakan dalam menganalisis crossflow dari multilayer reservoar. Crossflow adalah keadaan dimana masuknya fluida dari layer satu ke layer lainnya yang diakibatkan adanya perbedaan karakteristik antar layer . Analisa crossflow diuji dengan simulasi produksi tiap layer reservoar dan membandingkan antara jumlah produksi t iap layernya dengan produksi semua layer (commingle).Dari hasil penelitian menunjukkan bahwa Metode Jones -Blount- and Glaze merupakan metode yang paling mendekati dari test point sumur gas “x” dengan nilai AOF terbaik. Kemudian dari analisis crossflow yang dilakukan secara simulasi selama 1 tahun (2019-2020), terdapat gap dari kumulatif produksi gas tiap-tiap layer dengan kumulatif produksi gas secara commingle sebesar + 0.0379 MMSCF, hal ini disebabkan karena adanya perbedaan nilai permeabilitas horizontal dan tekanan antar layer. Dari analisis sumur “X” tersebut maka dilanjutkan ke pengembangan lapangan gas “Y” dengan simulasi didapatkan RF terbesar 89.38% dari total IGIP23.53 BCF

Abstract

The impacts of high dependence on oil on the economy have encouraged many countries to start eliminating or sharply reducing their dependence on oil consumption. As an oil importer as well as oil and gas producer country, Indonesia seeks to do the same thing by eliminating fuel subsidies, shifting to gas, and developing renewable energy. The oil price affects the economic and energy policies and impacts the efforts of reducing oil dependence. Using an econometric model of Indonesia’s energy that is constructed based on its energy balance model, this paper will examine factors that influence the oil demand in Indonesia. It will estimate the country’s energy needs from 2017 to 2030 and simulate various alternative strategies to deal with oil dependencies, such as an increase in the refinery capacity, and a shift from oil to gas in the transportation sector. This paper suggests that shifting from oil to gas in the transportation sector will be able to reduce oil dependency, while the alternative of increasing refinery capacity to 3 million barrel per day will be an opportunity to support greater short-term energy security and economic returns.

Abstract

Aims: This study aimed to increase the utilization of biomass-derived from the waste of coconut and peanut shells by making them as briquettes, as an alternative to fuel. The scarcity of petroleum because of its increasingly limited existence encourages all parties to take part in the development and discovery of new alternative energies. This is expected to overcome one of the most important of the many problems facing this country. The method used in this research is to start with a literature study of materials from various sources about the benefits and manufacturing of briquettes from biomass waste as an alternative energy source to be further tested for quality.  This involves a heat test, water content test, ash content test and determination of the flying matter. Results: The test results showed that natural gas emissions were below threshold, namely 0-30 ppm CO, 0-3.6 ppm H2S, and undetectable NOx. After evaluation, the results showed that with the addition of 30% of the biomass, the ignition time was reduced and the remaining unburned briquettes or bottom ash was reduced by 68.68%. Conclusion, significance, and impact of study: The results help the community and the parties involved related to appropriate bio briquettes technology. It also eventually becomes one of the solutions to assist the government in solving problems related to alternative fuels to petroleum.
