...Pore geometry and connectivity In exploiting hydrocarbon reservoirs, characterising subsurface dynamic dependencies is key. It is indeed the degree of heterogeneity within these to determine the uncertainty in identifying volumes and importantly in planning effective recovery. Existing...

... of a horizontal well or at different wells. The analytical model is first verified using a fully-coupled hydraulic fracture, reservoir, and wellbore simulator, and flowing pressure responses in the presence of different reservoir heterogeneities are then illustrated. Practical application of the proposed method...

... Abstract Carbonates exhibits diverse flow characteristics at pore scale. Petrographic study reveals micro-level heterogeneities. Thin sections are key to assess reservoir quality although these are images and interpretations in text format. Thin section microscopic analysis is descriptive...

... Abstract Oilfield A is a low relief structure consisting of multiple stacked reservoirs. Three reservoir intervals show different trends of reservoir property distribution. Lateral reservoir property degradation in Oilfield A is correlated to increased vertical heterogeneity. Understanding...

... an accurate porosity distribution. Currently, there are different methods for quantifying secondary and primary porosities by integrating different measurements and logs. Borehole image can solve the carbonate heterogeneity challenge when it comes to quantifying accurately the complex pore system distribution...

Despite its importance, many interpretative lithofacies association schemes fail to capture, in a clear, systematic and flexible way, the key environmental features affecting the depositional fabrics’ distribution and their associated reservoir quality. This is especially true in carbonate...

..., by dolomite cements. An emphasis has also been put on recognising the residual hydrocarbon, the abundance of which varies considerably at field scale. To better constrain the vertical and lateral distribution of the reservoir heterogeneities, nineteen layers of interest depicting the main reservoir quality...

... to enhance the number of outputs from the petrophysical workflow by providing recommendations on the optimal vertical layer size by stratigraphic interval for capturing all relevant heterogeneities associated with complex carbonate reservoirs. We assume that the deflections of the petrophysical logs...

... as any of the heterogeneity in the borehole image, however this method is applicable to any type of heterogeneities in an image. The CNN module is trained iteratively using a binary mask as a ground truth for each image, with 0 representing background and 1 pixels belonging to the class, using a loss...

... Abstract Carbonate reservoirs are highly heterogeneous and poor in interwell connectivity. Therefore, it is difficult to predict the thin oil layers and water layers inside the carbonate reservoir with thickness less than 10 ft by seismic data. Based on the petrophysical analysis with core...

... Abstract In a giant offshore UAE carbonate oil field, challenges related to advanced maturity, presence of a huge gas-cap and reservoir heterogeneities have impacted production performance. More than 30% of oil producers are closed due to gas front advance and this percentage is increasing...
