..., a conceptual heterogeneity pattern is used to control the spatial distribution of core and log data. Traditionally, seismic acoustic impedance or depositional facies map are the conceptual heterogeneity patterns used. Sometimes, facies map may be derived from limited wells, and seismic data is expensive...

... and gas volumes in place and model saturation distribution. The behavior of the primary drainage curve is controlled by the pore throat size distribution, where a much wider pore throat size distribution is observed for heterogenous reservoirs. The objective of this paper is to determine capillary...

... 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...

... 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 pertaining to Lower Cretaceous reservoir ‘A’ with over 4 decades...

(1999) conducted an experimental study to examine the effect of longitudinal heterogeneity on the tracer profile...

... 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...

.... 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 and at surface can also be observed and explained, especially the variations in vertical permeability. Then simple...

... 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...

... Abstract The evaluation of carbonate reservoirs is a complex task because of the inherent heterogeneities that occur at all length scales. Rock properties may be defined differently at different scales and this introduces a challenge in capturing heterogeneity in a single rock volume...

... 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...

..., and by making the size of the cells smaller, the heterogeneity was identified as the most important factor in modeling and monitoring the gas movement from the injected wells towards the production wells. Based on the new upscaling, two dynamic models were constructed. The original model had 267,000 grid cells...

... (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 of deposition. A wide range of trajectories is available, from the more...

... Abstract Carbonate reservoirs have complex pore structures and serious heterogeneity, which increase the difficulty to achieve efficient oilfield development. Conventional core plugs cannot accurately depict the heterogeneity characteristics that may beyond the scale of plugs. Thus, whole core...
