... ABSTRACT Carbonate rocks are responsible for a considerable amount of hydrocarbon reservoirs worldwide. In Brazil, a huge part of petroleum reserves is associated with carbonatic facies formed during Aptian and Albian times, specially on offshore basins of east coast. These sedimentary...

... with lower AI values and medium to high porosities. The tight carbonates stand out for their high values of AI and considerable decrease in porosity due to the influence of diagenetic processes of cementation and compaction. Muddy facies are associated with the lowest AI values, while porosity remains...

In this context, understanding pore-scale hydraulic efficiency of carbonate rock facies turns out to be one of the main tasks to accurately predict hydrocarbon...

... breccia-bearing tuff. The minerals and lithology varied a lot from well to well. Volcanic lithofacies include volcanic explosive facies and volcano-sedimentary facies. Good reservoirs are mainly distributed in breccia-bearing tuff, tuff, and volcanic breccia of explosive facies, with high albite content...

... ABSTRACT In this paper, we study one of the largest producing gas fields in SE Asia that supplies about 50% of the domestic gas demand. A petrophysical framework is constructed to estimate gas filled pore volume in the thin bedded facies (TBF). Subsequent perforations in the TBF and production...

... North Oman. This has been strengthened by a realization of the role of facies to trap hydrocarbons. When low Hydrocarbon Saturations are observed, it is important to understand if a structure was not charged at all, or if low Hydrocarbon Saturation is an artifact of poor facies encountered. In the worst...

These augment the information of the available measured logs and allow the definition of a physics-based interpretation model able to properly characterize both the reservoir and caprock layers. In addition, the most reactive facies to carbon dioxide are recognized...

... insights into the different processes that have occurred: from the moment of the deposition until the image acquisition. Each field, reservoir, well, and interval has a unique textural assemblage, consequence of its own depositional facies, diagenetic processes, geomechanics and wellbore conditions or well...

... Abstract An integrated technical study was conducted for a field development project in West-Hungary. This study offers a better solution for estimating petrophysical properties and fracture facies vertically along the well and laterally for 3D static and dynamic models of naturally fractured...

.... Conventional evaluation of the encountered heterogeneous mix of alluvial fans, plains, and aeolian dune facies is difficult, even more in horizontal drains where standard logs are often featureless across problematic conglomerates. Real-time dips picked on high-definition images helped with geosteering as well...

... Abstract Identifying depositional facies and diagenetic modifications from BHI logs in sections without core is challenging due to heterogeneities in fabric of the carbonaceous rock, which are below the resolution of the BHI logs in these complex reservoirs. This is mainly due to different...
