This approach provides a precise understanding of reservoir quality, enables quantification of hydrocarbon in place, and optimizes oil...

... treatment explicitly developed for the fractured carbonate reservoir in the Gulf of Suez basin in the Eastern Desert of Egypt. The challenge was to treat the lower-permeability matrix while achieving a well-defined acid distribution between the flow zones of the natural fractures and the unfractured matrix...

... Abstract Borehole images play a crucial role in understanding the depositional environment and diagenetic processes that govern fluid flow in Brazil's presalt carbonate reservoirs. Acoustic and resistivity image logs offer superior resolution compared to the other types of measurements normally...

... the needs of correctly predicting reservoir petrophysical properties in the 3D space requires that the geological processes driving the current organization of these properties have been correctly identified and characterized prior to the modeling phase. In the case of carbonate reservoirs, whether marine...

... Abstract The main goal of this work was to estimate carbonate porosity from sonic log S-wave slowness measurement, practically insensitive to fluid effect. Methodology is empirical and had already been successfully tested in sandstones ( Silva and Beneduzi (2018 )). Oolitic carbonate reservoir...

The results showed how optimizing WAG operations can significantly improve the economics and the scale management of oil production from carbonate reservoirs. The optimal WAG design greatly increased...

... influence on pores development for carbonate reservoirs. Reservoir physical properties decrease sharply after thermal baking, generally by 4 to 8 times. The study also confirms that related hydrothermal fluids pervasively develop and have multi-types of influences on limestones, mainly due to silicification...

... Abstract Wettability is an important property in reservoir characterization. For the heterogeneous carbonate reservoirs in the Brazilian Pre-Salt, parameters that represent wettability are needed to obtain improved reservoir models. In this work, we applied contact angle measurements to analyze...

... Abstract The low salinity water injection (LSWI) is one of the most studied techniques applied to enhanced oil recovery (EOR) from carbonates reservoirs. Wettability alteration and dissolution reaction are mechanisms that support the understanding of this technique. However, the dissolution...

... Abstract Carbonate reservoirs in the Middle East are characterized by strong heterogeneity, fairly subtle barriers and baffles, which result in low water flood swept volume and poor displacement efficiency. Therefore, optimum well pattern deployment is critical for high-efficiency development...

... Abstract In the past decades, water injection development with horizontal wells is seeing more implementations and achieves considerable benefits for carbonate reservoirs in the Middle East. However, significant problems such as early water breakthrough (WBT) and uneven displacement pose great...
