Abstract
ABSTRAK Penelitian ini dilakukan di PT. Kitadin Embalut, Lapangan L 3, Kec. Tenggarong Seberang, Kabupaten Kutai Kartanegara, Provinsi Kalimantan Timur. Daerah penelitan ini masuk ke dalam Formasi Balikpapan yang merupakan formasi pembawa batubara. Penelitian menggunakan data well logging, log gamma Ray pada 6 sumur. Penelitian dilakukan dengan tujuan menganalisa defleksi kurva well Logging serta menghitung nilai volume shale untuk mengetahui karakteristik lapisan batubara dan hubungannya dengan kualitas batubata di daerah penelitian. Analisa data didukung oleh data uji laboratorium berupa kandungan abu, kalori, total moisture dan total sulfur Berdasarkan hasil penelitian diketahui bahwa ketebalan batubara didaerah penelitian bervariasi. Kehadiran parting terbukti mempengaruhi kualitas batubara sehingga pada lapisan batubara yang sama kualitas dapat berbeda. Kehadiran parting dapat dilihat langsung dari kenampakan kurva log gamma ray yang dicirikan dengan peningkatan nilai v shale secara tiba-tiba. Abu merupakan pengotor pada lapisan batubara yang dapat menurunkan kualitas batubara. Nilai koefisien determinansi menunjukkan hubungan antara v shale dan abu batubara sangat kuat dengan R2 = 0,8059 sehingga dapat dijelaskan pula bahwa v shale merupakan faktor dominan penurunan kualitas batubara. Kata kunci : log gamma ray, v shale, abu, kalori, kualitas ABSTRACT This research was done at Kitadin Embalut Company, L3 Field, Tenggarong Seberang District, Kutai Kartanegara Regency, East Kalimantan Province. It area is part of Balikpapan Formation which is the coal barrier formation. Research using well logging data, gamma ray log at 6 wells. It aims to analyze the deflection of well logging curve and calculating the volume of shale to determine the characteristic of the coal seam and its relation to quality of coal in the reseach area. Data analysis is supported by laboratory data such as ash content, calorific value, total moisture and total sulfur. Based on research results revealed that the thickness of the coal in the study area varies. The Presence of parting was proven to influence coal quality so that same seam have different quality. The present of parting can be seen directly from the appreance of gamma ray log kurve which is charactized with increased of shale volume value suddenly. Ash content is an impurity that can decrease quality value of coal seam. Coefficient of determination value shows the relationship between volume of shale and ash content of coal is very strong with R2 = 0.8059 so it can be explained that volume of shale is a dominant factor to reduce coal quality Keyword: gamma ray log, v shale, ash content, calorific value, quality
