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

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.
