Additionally, with inverted standoff images, open and closed natural fractures were identified and utilized in the fracture modeling of the field. All the forementioned identified features have been incorporated into the facies...

... facies and rock-types, distributions of petrophysical variables, etc.), data analysis before modelling favors an understanding of reservoir heterogeneity at the scale of the field, to the detriment of a more regional understanding. Reservoir modeling techniques, which to date are essentially...

... confirmed by low instantaneous frequency and low amplitude in the Spectral Decomposition study. Core data analysis in Fatehgarh formation suggested presence of considerably more reservoir facies in the system compared to what is visible in wireline log. Drill cuttings data from wells across the field also...

... properties. We implemented mean-squared error and L1 norm as the loss functions during the training process. The L1 norm is the mean absolute values of the predicted hydrocarbon saturation, which can help promotes sparsity. The network learns on synthetic dataset. We use facies-based geostatistical...

... Abstract This study had been performed to map the lateral and vertical heterogeneity of carbonate reservoir, using the newly acquired Ocean Bottom Node (OBN) data. Joint PP-PS pre-stack inversion has been performed to delineate the facies distribution and associated properties such as porosity...

..., with regular interval capturing all facies. Removing outliers and harmonizing core geological-petrophysical measurements and logs is a key. The rock-typing workflow generates Static Rock Types (SRT) in core domain by integrating Petrophysical Groups (PG) with Candidate Rock Type (CRT), then propagating to 1D...

.... The former ones were very useful in understanding the sedimentary basin evolution while the other set of maps were useful in understanding the sedimentary processes which controlled the facies distribution and hence reservoir potential identification. In parallel to the correlation and the thickness mapping...

... facies (mainly micrite and stylolite) in the Lower Reservoir. The study highlighted that the field was exposed to a paleo-temperature peak higher than the current reservoir temperature that transformed both types of tar into pyrobitumen, a solid carbon form with no potential for exploitation. Predicting...

These stages should be understood step-by-step following geological evolution of a reservoir. However, geologists who describe cores and interpret depositional...

... regionally seals Shuaiba Formation and underlies Natih Formation; both are prominent carbonate reservoir in northern Oman. The NULMU often presents hydrocarbon shows in the subsurface but has never been targeted as a reservoir or studied in detail. This study focused on understanding the lithology, facies...

... geomechanically stable under the current in-situ stress condition. The study concluded that the predominant root-cause of severe lost circulations in the carbonate reservoir was cave-related rocks (cave facies) and excessive overbalance applied to reservoir pressure. The cave facies were supposed to be formed...

... developed in grainy facies with intergranular macro pores from shoals and moderate-energy lagoon settings. During later diagenesis, non-selective dissolution, dolomitization and late-stage cementation in these facies resulted in tortuous pore throat and low-connected secondary micro-meso pores. In low...

Submarine channels were cut into the shelf edge along the compressional thrusting front (in the present near offshore of RAK), and basinal fans can be observed in the present-day offshore 3D seismic. The calciturbidite facies has been identified in several wells with clear hydrocarbon shows and successful...

Newly acquired 3D seismic data, existing well data and regional information have been utilized for seismic interpretation and litho-facies analysis to characterize Shuaiba Sequence 5. These interpretations were then linked...
