... term to describe different shapes of capillary pressure curves that cannot be modelled by equation 1 or equation 2 . Equation 3 was introduced to fit experimental p c data for complex and heterogeneous rock types that are characterized by dual porosity (e.g., bi-modal pore size distributions...

... Abstract A tight oil reservoir is characterized by developed natural fractures, strong heterogeneity, and anisotropy. During long-term production, the geomechanical parameters change accordingly, which results in the difference in hydraulic complex fracture propagation between the infill well...

... and determine vertical permeability (Kv) and permeability anisotropy (Kv/Kh). Abstract Carbonates are infamous for their complex intrinsic heterogeneity, exaggerated due to stratification and layered geology. Characterization and correlation of this heterogeneity with recovery mechanisms becomes critical...

The case in hand illustrates the advantage of data integration between Logging While Drilling (LWD) including Nuclear Magnetic Resonance (NMR), High-resolution image...

...-well tracer tests have numerous applications in determining the volumetric sweep, levels of heterogeneity, and delineation of flow barriers such as the faults in subsurface in reservoirs. Tracer tests are also performed in the laboratory to determine core samples’ heterogeneity. Simulation of physical...

Starting (base-case) scenario, investigating whether pressure clusters could be used to differentiate between the wells within...

... of the thief zone are particularly important for the waterflooding in carbonate reservoir ( Wei et al., 2017 ). In general, carbonate reservoir has strong heterogeneity, and the thief zone influence the development of a field ( Ghedan et al., 2010 ; Liu et al., 2018 ). The word "thief zone" refers...

... characterized by high heterogeneity. First, the MRGC has been carried out in order to obtain an alternative log-facies classification with an inherent textural meaning. Next, the WT-based algorithm provided a robust quantification of the secondary porosity contribution to total porosity, in terms of connected...

... based on compositional thermal simulations coupled to a fully laboratory calibrated SARA-based chemical model. Composition of the pre-steam, post-steam and produced oil are compared to understand the effect of the aquathermolysis reactions. The impact of heterogeneities on H 2 S production both in-situ...

... process but it generated severely uneven distributions of temperature, pressure, and saturation around wells due to the high reservoir heterogeneity. An improved steam circulation start-up methods instead of cycle steam stimulation is needed to overcome the problems. We developed an optimization method...

... the core length ( Wellington and Vinegar, 1987 ). This technique has recently been applied on cores in shales for accurate evaluation of sweet spot locations ( Walls and Armbruster, 2012 and Almarzooq et al., 2014 ), and in carbonates for mineralogical variations, heterogeneity and sample selection ( Al...

... sandstone reservoirs all aroud China. To sustain the production, a more detailed and integrated heterogeneity characterization is in demand for later reservoir development adjustment to mitigate the deterioration. Different from conventional reservoir development, reservoir stimulation is necessarily...

... Abstract The Burgan Sand reservoir is the largest and most prolific reservoir in the Greater Burgan field in Kuwait. As development of this reservoir proceeds, greater attention is being paid to the more heterogeneous upper part of the reservoir, the Upper Burgan Sands, which contain...

The 3D Geocellular grid obtained from 3D seismic cubes was applied to dynamic model, and by making the size of the cells smaller, the heterogeneity was identified...

... effect of low uncertainties linked to the difficulties quantifying this ratio (local heterogeneities, core sampling, etc.) can lead to abandonment of the horizontal well project. To minimize the risks, an appropriate solution is to drill almost horizontally, but not parallel to the stratigraphy or system...
