| Summary: | Log and core analysis are 2 main sources to characterize the reservoir. Logging provide
information in wider interval compare to the core but it has limitation due to log
measurement and interpretation. Core samples provide more accurate result for certain
depths and it need to upscale to analyze the saturation result in wider interval.
Well logging and data obtained from core analysis are usually combined together to
determine initial saturations of the fluids in the reservoir. Measurements of capillary
pressure is considered one of the main data of the core analysis. Capillary pressure
measurement indicates the volumetric behavior of fluids of the reservoir in static
condition in the reservoir rock. In the case of prior knowledge of the level of free water
and with the availability of capillary pressure data, one can restore initial water saturation
in the reservoir. Saturation-height functions (denoted by, SHF) used in this study to
integrate the result of saturation from core and log.
Saturation-height function has got a huge effect on reserves in place calculations. SHF
can predict reservoir fluid saturation at a chosen height from the level of free water and
it’s widely utilized by both petrophysicist and reservoir engineers. |
