Abstract

Smart waterflooding has proven successfully improving oil recovery in numbers of laboratory and field scale applications. The phenomena behind the positive outcome is concluded to be wettability alteration. The smart water composition changes the wettability of the rock surface into partially water-wet, thus promoting a spontaneous imbibition of the aqueous phase and displacing the oil. However, there are some mechanisms causing the wettability alteration that have been proposed by researchers. The present study examines the oil recovery from spontaneous imbibition tests by modifying certain ion composition of the smart water. Prepared core samples with initial water and oil saturation were immersed in spontaneous imbibition cells filled with smart water and the oil recovered was monitored for some period of time. The predesigned smart water compositions consist of different ions concentration, i.e., Na+, Ca2+, and Mg2+, while maintaining identical total dissolved solid (TDS). The experimental results found that the ion composition of smart water affects the oil recovery regardless of the TDS, and low Ca2+ and Mg2+ concentrations shows the highest recovery factor.

Abstract

Aspek Keselamatan dan kesehatan kerja (K3) wajib untuk dipahami oleh setiap pekerja dan pemilik usaha. Namun demikian masih banyak pekerja maupun pemilik usaha yang belum memahami aspek K3, padahal apabila diterapkan dengan benar dapat membantu meningkatkan kesejahteraan dan produktivitas kerja baik bagi pekerja itu sendiri maupun pemilik usaha. Sosialisasi ini dimaksudkan untuk memberikan pemahaman mengenai aspek-aspek K3 di lingkungan CV Rumah Kampung. Pemahaman ini diperlukan untuk memastikan bahwa setiap pekerja terlindungi dan terjamin keselamatannya di tempat kerja dan setiap sumber produksi perusahaan dapat digunakan secara aman dan efisien. Sosialisasi ini diikuti oleh pemilik, manajemen dan seluruh karyawan Perusahaan Rumah Kampung. Dari diskusi yang dilakukan selama sosialisasi, terungkap bahwa Perusahaan Rumah Kampung sudah menerapkan sebagian aspek K3 meskipun belum seluruhnya, sesuai yang diharapkan oleh pemerintah seperti yang tercantum dalam UU No. 1 Tahun 1970, tentang keselamatan kerja. Sosialisasi ini telah membuka wawasan pemilik usaha Rumah Kampung dan para pekerja mengenai pentingnya penerapan aspek-aspek K3 yang benar, sehingga setiap pekerja dapat terlindungi keselamatan dan kesehatannya, serta aset-aset perusahaan juga terlindungi. Tentu saja adanya kesadaran setiap pekerja untuk melindungi setiap aset perusahaan sangat diperlukan untuk keberlangsungan hidup perusahaan dan untuk menjamin keberlangsungan hajat hidup pekerjanya.

Abstract

Jika kelayakan Kontrak Kerjasama hulu minyak dan gas bumi diukur oleh kontraktor berdasarkan indikator keekonomian, maka apakah yang menjadi indikator kelayakan bagi pemerintah kita? Tulisan ini memaparkan studi berdasarkan data literatur mengenai penerimaan minimal bagi negara dari Kontrak Bagi Hasil Produksi hulu minyak dan gas bumi. Berdasarkan ketentuan kontrak bagi hasil, dapat dihitung minimal penerimaan negara. Selain itu, data-data realisasi produksi tahunan dari kontrak bagi hasil dapat memberikan angka statistik penerimaan negara setiap tahunnya.     Kata Kunci : kerjasamahulu minyak dan gas bumi, kontrak bagi hasil, penerimaan negara.   Abstract The feasibility of upstream oil and gas Cooperation Contracts is measured by contractors based on economic indicators. What then is the feasibility indicator for our government? This paper describes a study based on literature data regarding minimum revenue for the state from upstream oil and gas Cooperation Contracts. Based on the terms of the production sharing contract, a minimum state revenue can be calculated. In addition, data on the realization of annual production from production sharing contracts can provide statistics on state revenue each year. Keywords: upstream oil and gas, production sharing contract, minimum state revenue.

Abstract

Indonesia memerlukan usaha eksplorasi yang banyak untuk meningkatkan cadangan dan produksi nasional. Banyaknya eksplorasi memerlukan investasi yang besar. Investasi yang besar memerlukan usaha untuk menarik minat investor. Salah satu usaha menarik minat idnvestor adalah dengan memberikan data klasifikasi resiko geologi dari cekungan hidrokarbon. Tulisan ini memaparkan cara sederhana dalam mengelompokkan tingkat resiko geologi dari beberapa cekungan. Faktor pengelompokan didasarkan kuantitatif pada petroleum system: batuan induk, reservoir, tutupan, jebakan, migrasi, patahan, dan perlipatan. Sebagai sampel, telah dipilih beberapa cekungan yang bisa mewakili cekungan yang dikenal sebagai frontier, semi mature and mature. Berdasarkan kuantitative keberdadaan petroleum system tersebut, maka cekungan dikelompokkan menjadi beresiko sangat tinggi sampai beresioko sangat rendah. Kata kunci : petroleum system, analisis kuantitatif, faktor resiko geologi, cekungan Abstract Indonesia requires a lot of exploration effort to increase national reserves and production. Lots of exploration requires a large investment. Large investments require effort to attract investors. One of the efforts to attract investors' interest is to provide geological risk classification data from hydrocarbon basins. This paper describes a simple way of classifying the geological risk levels of several basins. The grouping factors are based on the quatitative of petroleum system: source rock, reservoir, seal, trap, migration, fault, and fold. As a sample, several basins have been selected which can represent basins known as frontier, semi mature and mature. Based on the quantitative existence of the petroleum system, the basins are grouped into very high risk to very low risk. Keywords: petroleum system, quantitative analysis, geological risk factors, basins.

Abstract

In month of August, year 2021, there was an alteration in the production-sharing contract for this field. The contract previously used was Production Sharing Contract (PSC) Cost Recovery, which changed to PSC Gross Split. This contract comparison aims to synergetically evaluate the comparison of the two economic models and also to determine a more efficient and appropriate scheme to be applied to field A, as well as to analyze the parameters that can affect the economic indicators of field A. The results of the economic analysis that has been carried out show that the PSC Gross Split scheme is better than the PSC Cost Recovery scheme. For PSC Cost Recovery, the Net Present Value (NPV) obtained for 30 wells is equal to 13,848,000 US$, the average Interest Rate of Return (IRR) is 118%, the average Pay Out Time (POT) is 1.43 years, the Contractor Take is 20,740,000 US$, and the Government Take is 176,587,000 US$. Whereas for PSC Gross Split, the NPV obtained for 30 wells was US$ 37,906,000, the average IRR was 245%, the average POT was 1.30 years, the Contractor Take was US$ 52,544,000, and the Government Take was 136,402,000 US$. The sensitivity analysis that has been carried out shows that the parameters of the amount of oil production and the price of oil have a significant effect on both schemes.
