Abstract
PT.Virginia Indonesia Company (PT. VICO) is one of the oil and gas company which production of coal bed methane. The company is located in East Kalimantan province with the basin are processes namely Kutai Basin. Calculation of methane gas in place of coal bed can be done by several methods such as : material balance, volumetric and desorption test. Each method has its advantage and disadvantages. The method that used by PT. VICO to calculate gas in place at the moment is only the method of material balance. By using that method for calculating gas in place considered less accurate. Therefore we need other method of calculation of gas in comparison and evaluation of whether the value obtained relatively the same. One method of calculation, named volumetric method. This research will analyze the determination of the methane gas in place of coal using a volumetric method at Mutiara field PT VICO, East Kalimantan. The result of this study can be used as a reference company for comparison calculation which method already exists.
