Hydrocarbon Characterization in Jatibarang Volcanic Fracture Reservoirs
Research of hydrocarbon reservoir rock of fracture volcanic in the world still rare because of the limited invention of hydrocarbon at that reservoir. Geophysical well log until now where made for the sake of interpretation of carbonate and sandstone reservoir in consequences if it is used or utilized for interpretation fracture volcanic rocks will give very unique response .
This research aim to develop a method for the hydrocarbon characterization in volcanic fracture reservoir with area research of Jatibarang Field ,West Jawa ,Indonesia which covering the prediction of the volcanic , which determining the value of property of the porosity, exponent of saturation ( n), exponent of cementation ( m) , formation factor ( F) and tortuosity ( a) use log data , which is validation with core data, and production data. Besides that This research also conducted a determination of hydrocarbon zone with qualitative and also quantitative method with the calculation methods of new saturation which represented of saturation equation modification of Archie which is usually used in carbonate and sandstone.
In this research also made the correlations of corrective saturation which yielded to nature of rock physical like Poison Ratio, Sigma, Shear Modulus, Lame Constanta, Bulk Modulus, Young Modulus and Acoustic Impedance which is entirely alighted from Compression Wave Velocity (P) and Shear Wave ( S), based on the nature of physical of litology and fluid which is record at log response and also quickly creep measurement both wave in each rock type of reservoir in laboratory .
