The Cretaceous Mishrif reservoir is the main conventional pay zone of the Rub Al Khali Basin in the Middle East. However, previous study on the tight carbonate rock of Shilaif Fm. i.e., the directly underlying Formation of the Mishrif, was mainly focused on the source rock property. Currently, there are only limited studies of the tight reservoir property and exploration potential for the Shilaif Fm. In this paper, the tight carbonate rock of the Shilaif Fm. in Abu Dhabi is examined. Analysis of the sedimentary face and a comprehensive evaluation of the “three properties” of the tight Shilaif Fm. are carried out based on the core, logging, and seismic data. The facies association model and HC accumulation assemblage model are firstly established for both the Shilaif and Mishrif Fm. in the study area. The study results suggest that the slope shoal subfaces and intertidal subfaces are widespread in the Shilaif Fm. under the setting of platform slope faces, with the slope shoal subfaces providing a favorable zone for reservoir development faces. The results of the “three types of properties” evaluation show that the Shilaif Fm. is composed of gray wackestone and micritic limestone, with good hydrocarbon source rock and medium engineering quality, and somewhat poor reservoir quality. The Shilaif Fm. has low porosity and extremely low permeability which is a typical unconventional tight carbonate reservoir. According to the established sedimentary face model and the reservoir-forming assemblage in this study, in conjunction with the current exploration and development of the main Mishrif Fm. pay zone, a comprehensive evaluation was conducted to delineate the favorable zones in the study area with “both conventional and unconventional explorations”. The method and achievements acquired from this paper will provide a unique insight and effective technical support for quickly determining potential directions and screening targets for unconventional reservoirs in the similar regions.
