Reservoir Characterization Analysis

The process  of  carrying  out  petrophysical analysis  produces  data  that  are very  necessary for  the identification  and  manufacture  of  reservoir  models  and  estimation  of  hydrocarbon  reserves.  The resulting data is a petrophysical analysis of logging interpretation; interpretation is done by reading and comparing logging response. In this study, the determination of porosity, permeability and water saturation will be carried out [1].  After that, log data analysis was performed using the results data from well logging in the form of recording physical parameters of the depth which aims to obtain petrophysical parameters [2]. To obtain a valid analysis result, the results of the hydrocarbon zone analysis using log data are validated with core data using RCAL (core analysis laboratory routine) [3]. Cores can also be called core samples are parts of material or substances taken from the wellbore.
Core samples are the most trusted source of information because they directly take samples on drilled well rock. This causes the wells which are carried out by core data analysis to become reference wells as quality control from the results of interpretation and petrophysical calculations for other wells to be drilled around the reference drill. Core data itself is data generated from sample core analyzed in the laboratory in the form of physical parameters of rock [3]. Interpretation is done with log data and core
data to obtain the physical parameters of the formation needed so that it can be ascertained the exact range  of  petrophysical parameters  such  as  permeability,  porosity,  water saturation,  reservoir  zone spread and the making of ELAN models from the interpretations made.
