... structure & geological conditions, deeper reservoir burial and worse reservoir characteristics, fast decline, low recovery and high cost these all make it very hard to develop these kinds of reservoirs. In this paper, we firstly introduced the geology and reservoir characteristics of unconventional...

... After collecting and analyzing the operational, failures and DIFA data, the corrosion mechanism in the field was identified to be due to the existence of CO 2 (sweet corrosion). With the rise in water cut percentages throughout the reservoir life which led to water wetting in the tubing...

... formation, and it causes the formation only presents in both western and eastern flank of the field. Furthermore, the upper part of carbonate formation was also eroded in some part of the oil field. The current development scenario is to produce the oil from three main oil-bearing reservoirs, Reservoir...

... dolomites, further increasing the complexity of the reservoir. Furthermore, after deposition, carbonate rocks undergo diagenesis, which further complicates the characteristics of the reservoir. Decomposing these heterogeneities and complex geological elements to construct accurate rock types is crucial...

...Introduction: Fluid movement in Fractured Carbonates Abstract The understanding of reservoir fluid pathways and their dynamic behaviour through time is essential for a successful development of a fractured carbonate reservoir. This work aims to propose an adaptable data analysis workflow...

... Specifically, the low clay content contributes to reduced gamma ray counts, posing difficulties in layer identification. Moreover, the hydrocarbon-bearing pay zones exhibit a high-resistivity response, complicating the identification of sweet spots within the reservoir. The original pore system...

... Hydraulic fracturing technology increasingly being used to enhance the efficiency of oil and gas exploration and extraction. In hydraulic fracturing, proppants are widely used to fill the fractures and increase reservoir permeability ( Denney, 2008 ), thereby improving the efficiency of oil...

..., this points were used to back calculate reservoir pressures at that time, however the absolute values of this points increased from 2000 to 2600 psi in 9 years, may be due to increase in reservoir pressure or phase segregation in wellbore during S.I. period.

... Abstract Carbonate reservoirs have different approaches to acid stimulation techniques. In order to achieve the most effective results, it varies by utilizing different diverters, acid systems, and pumping types. Even after improving the coiled tubing placement and numerical model predictions...

... Abstract Excess water production is becoming a major problem in mature oil fields as the oil reservoir is subject to long water flooding process. As the oil field matures, producing more oil out of maturing reservoirs entails more water production. It is essential to have a robust water...
