Abstract

The church  music has long history. It began  when they, the believers,  mentioned themselves as the “Christian”. The existence of church  music more  developed till middle age  or  dark  age  period.  The church music  was  dominantly  covering  to  others  music  genre.  At the  Renaisance  Period  the  church  reformation movement occured and it was pioneered  by Martin Luther. Western music changed at the time. Luther changed the tradition  of Catholic  church that used Latin lirics to folk language.  At the present day we are familiar with charismatic  music tradition  which is developed from American music tradition.  It has a charracteristic which is used as the band instrument in praise  and worship by christian  believers. But sometimes, the believers also use arpeggio  or broken-chord  as the main character on Classical  Period  in part the way of Western music history. Pass through the reasearch, the reasearcher look into the idioms are used in praise and worship in STT Kristus Alfa Omega  Semarang.  The researcher found that  the using  of idiom in Classical  Period  have enriched  the nuance of music aesthetic in praise and worship

Abstract

Natural CO₂ reservoirs represent important analogues for Carbon Capture and Storage (CCS) and Carbon Capture, Utilization, and Storage (CCUS), as they provide direct evidence of long-term CO₂ retention and trapping mechanisms. This study assesses porosity in a natural carbonate CO₂ reservoir using an integrated density–resistivity log approach. Conventional porosity logs, such as density, neutron, and sonic, often overestimate porosity in carbonate systems due to their limited sensitivity to pore connectivity. To overcome this limitation, density log-derived total porosity was integrated with resistivity-derived effective porosity, allowing for the differentiation between connected and isolated pore systems. Fluid density estimations, including supercritical CO₂ and brine, were computed and validated against standard references to ensure accuracy. The results show that density-only porosity overestimates values by up to 10% in dolomitic intervals, whereas the integrated method provides estimates that are more consistent with core measurements. Isolated porosity, averaging 2% in the upper dolomite and 1.5% in the lower dolomite, was identified as a non-contributing pore volume for injectivity, although it remains relevant for storage capacity. These findings underscore the importance of integrated log interpretation for precise reservoir characterization and offer new insights into evaluating natural CO₂ reservoirs for long-term geological storage.
