Average Absolute Percentage Error (AAPE) and coefficient of determination (R 2 ), Structural similarity index (SSIM), and Peak Signal to Noise Ratio (PSNR) are used as error metrics to evaluate the performance...

... Abstract Evaluation of petrophysical properties such as porosity, permeability, and irreducible water saturation is crucial for reservoir characterization to determine the hydrocarbon initially in place and further optimize hydrocarbon production. However, estimation of these parameters...

... Summary Unstable supply of renewable energy arises with the inevitable seasonal dependency, which contradicts with periodic energy demand. As hydrogen shows high energy density and mobility, yet low solubility and residual saturation, underground hydrogen storage (UHS) becomes a promising...

... Abstract This paper explains the importance for implementation of early water flood in near saturation pressure oil reservoirs particularly for the case having solution gas as dominant drive mechanism. The depletion in case of solution-gas drive (having no or minor support) with low to moderate...

... Abstract Primary drainage capillary pressure data are essential input for static modelling of hydrocarbon reservoirs, estimate both oil and gas volumes in place and model saturation distribution. The behavior of the primary drainage curve is controlled by the pore throat size distribution...

.... The measurement was conducted using one oleic and one aqueous phase, applying different fractional flow steps, mimicking the range of varying water saturation in the reservoir during the depletion process. The used microchip has a synthetic pore-structure design with circular grain shapes. The measurements...

... Abstract For decades, it has been affirmed that pulsed neutron (PN) spectral Carbon/Oxygen (C/O) logging is the industry's most robust salinity-independent means for reservoir saturation monitoring (RSM); yet C/O logging still comes with considerable uncertainty that has to be identified...

... Abstract NMR assisted capillary pressure and water saturation measurements have proven to be significantly faster than traditional porous plate and centrifuge methods. The NMR directly measures water saturation along the length of the core and associated capillary pressure generated at a given...

... Abstract Most of the oil remain trapped in the reservoir after both primary and secondary recovery stages. Enhanced oil recovery (EOR) techniques are usually implemented in the tertiary stage to recover the trapped oil. Accordingly, the inaccurate determination of residual oil saturation after...

... and hydrocarbon saturation. The method of log-to-log comparison is popular for its simplicity and speed of use in real-time but is not enough for certain scenarios. For example, the real-time log response can be very different from modelled log response in the presence of gas or very light oil, irrespective...

... Abstract Monitoring fluid saturation and reservoir surveillance are essential techniques for effective reservoir management. As reservoirs age and water sweep advances, it becomes more difficult to find infill well placements. Reservoir scale saturation surveillance technologies offer a novel...
