Abstract
Telah dilakukan pengukuran well logging dengan metode akuisisi data Log Inside Casing. Akuisisi data dilakukan pada 34 sumur bor di Formasi Balikpapan, daerah Separi, Kabupaten Kutai Kartanegara, Provinsi Kalimantan Timur. Penelitian ini bertujuan untuk mengetahui perbedaan nilai densitas hasil pengukuran metode akuisisi data Log Inside Casing dan Log Outside Casing serta untuk mengetahui hubungan densitas batubara hasil pengukuran Log Inside Casing dengan kualitas batubara. Dilakukanlah pengolahan data dimulai dengan melakukan interpretasi terhadap grafik well logging untuk memisahkan litologi batuan formasi dibantu dengan data inti bor dan model geologi daerah penelitian. Selanjutnya dilakukan perhitungan untuk mengetahui densitas batubara daerah penelitian, kemudian dilakuakn uji beda untuk mengetahui perbedaan nilai densitas batubara data Log Inside Casing dan Log Outside Casing. Serta dilakukan Cross Plot, uji beda serta uji korelasi untuk mengetahui hubungan nilai densitas batubara terhadap kualitas batubara. Hasil yang diperoleh adalah perbedaan nilai densitas Log Inside Casing dengan rata – rata 1,7 gr/cc dan Log Outside Casing dengan rata – rata 1,39 gr/cc. Terdapat perbedaan pula antara nilai densitas Log Inside Casing sebesar 1,75 gr/cc dan Relative Density sebesar 1,34 gr/cc. Berdasarkan hasil Cross Plot antara densitas batubara Log Inside Casing dengan kualitas batubara menunjukan ada hubungan yang kuat antar variabel - variabelnya. Pada densitas dengan total moisture menunjukan adanya hubungan korelasi negatif dengan R2 = 0,674. Pada densitas dengan volatile matter menunjukan adanya hubungan korelasi negatif dengan R2=0,6416. Hubungan antara densitas dengan calori value menunjukan hubungan korelasi positif dengan R2= 0,5946. Densitas dengan ash contain memiliki hubungan korelasi negatif dengan nilai R2= 0,532. Kata Kunci : Well logging, Log Inside Casing, Log Outside Casing, densitas batubara, kualitas batubara, Cross Plot. Well logging measurements have been carried out with the method of data acquisition Log Inside Casing. Data acquisition carried out on 34 bore hole in Balikpapan Formation, Separi Region, Kutai Kartanegara Regency, East Borneo Provice. This research aims to know the differences between the density of the measuring result methods of data acquisition Log Inside Casing and Log Outside Casing as well as to know the connection of coal density measurement result Log Inside Casing with coal quality. Data processing was undertaken starting with the interpretation of well logging graphics to separate of rock lithologi formation assisted with the core data and geology model of the research area. Then do the calculation to determine coal density of research area, then a different test done to find out different between the coal density of Log Inside Casing and Log Outside Casing. As well as done a Cross Plot, different test and correlation test to know the connection between coal density and coal quality. The results obtained are differences in the density Log Inside Casing with average of 1,7 gr/cc and Log Outside Casing with average of 1.39 gr/ cc. There are also differences between the density of Log Inside Casing is 1,75 gr/cc and Relative Density is 1,34 gr/cc. Based on the results of Cross Plot between coal density of Log Inside Casing with coal quality showed a strong correlation in variables. Between total moisture and density showed a negative correlation with R2 = 0.674. Between volatile matter and density showed a negative correlation with R2 = 0.6416. The connection between the density and calori value showed positive correlation with R2 = 0.5946. Between density and ash ontain have negatif correlation with R2 = 0.532. Keyword: Well logging, Log Inside Casing, Log Outside Casing, coal density, coal quality, Cross Plot.
