Abstract

The recent eruption of Kesongo mud volcano (MV) that occurred in 28August 2020 in Blora, Central Java was a common natural phenomenon.MV eruption occurred periodically depending on the recharge fluid systemthat interconnected to a geothermal system and hydrocarbon reservoir.During the eruption, methane and CO2 gas were emitted to theatmosphere together with rocks, muds and fluids flowing from the fractureand fault system of MV. The extruded materials could be harmful andbeneficial for the affected ecosystem. Aims: This study aimed to addressthe potential impact of the extruded mud volcano materials to theenvironment. Methodology and Results: An attempt was carried out byinvestigating gas and fluid content of every mud volcano morphology in theselected 11 areas of Kradenan, Central Java and Sidoarjo, East Java. The pristine fluids and gas of MV were sampled for chemical and toxiccompound observation. Gas composition and type was observed using gaschromatography. The result shows that methane gas content ranges from0.06 to 67.6 mol%., while the CO2 content ranges from 0.21 to 79.9 mol%.Methane gas exhibits thermogenic gas that associated with hydrocarbongeneration. Conclusion, significance and impact study: The chemicalcompound of fluids indicates high Boron (B) content above 0.5 ppm whichhas harmful effect for crops and human health, but some compounds ofCa, Na, K, Mg present as essential elements for soil nutrient. According tothe methane flux and chemical compound emitted by mud volcano, thisstudy contributes to a management practice to restore and conserve the global ecosystem.

Abstract

The term "electrofacies" was introduced in 1980 by Serra and Abbott, it had been developed promptly since 2009. The development was triggered predominantly by wireline logging technology and artificial intelligence technology. The electrofacies categorization was intended to facilitate the study of reservoir characterization. However, it is difficult to formulate deterministically, due to the uniqueness of the depositional environment and geological processes that involve many physical properties. At least, there are 369 articles which were obtained from Scopus sources in the period of 1980 - 2021. In this bibliometric analysis, we regrouped the articles into four groups, i.e. “pattern recognition” “facies analysis”, “objectives” and “quality”. This grouping was attained on the methods of co-occurences, co-authorship, citation analysis and bibliographic coupling using VOSviewer software. The distance and coupling between themes will determine the level of quality and quantity of discussion between them. The quality of the objective resides in the certainty value of the lithology controlled by transportation or diagenetic events. For example, sand and shale which are siliciclastic lithology will have a higher degree of certainty than carbonate rocks. Therefore, the wide gap occurred during the application of artificial intelligence, especially for complex facies and uncertain geological conditions. The application of artificial intelligence is not solely functional without involving geological analysis. The implication is some researchs are still needed from this point of view, so the electrofacies role cannot be independent without developing models of the diagenetic process.
