Search and Discovery Article # ()** Posted Janu This study shows that geomechanics-based methods efficiently capture the occurrence of natural fracture systems and reveal the production-controlling factors of the tight gas reservoir. It demonstrates that geomechanics is a powerful tool to support successful exploration of the tight gas reservoir in tectonically stressed environments.

The Production Logging Tool (PLT) is commonly used to allocate the production to the individual layers. In order to generate heterogeneity, the spherical variogram type is used.

We set up the correlation length of and ft in the x and y direction, respectively. The nugget effect is used to generate discontinuity between data in reservoir. Larger nugget value causes more discontinuity and more heterogeneity. Compared to conventional reservoirs, the pore structure of shale presents strong heterogeneity and anisotropy.

Pore heterogeneity determines the heterogeneity of gas occurrence and pore anisotropy determines the optimal direction of flow. As a result, a quantitative characterization for shale heterogeneity is urgently-needed for more accurate assessment of gas reservoir capacity and a quantitative characterization for shale anisotropy is of great significance for the optimization of gas Cited by: 9.

One IOR method is infill drilling, which improves hydrocarbon recovery from virgin zones of the reservoir. Determining the appropriate location for the infill wells is very challenging and greatly depends on different factors such as the reservoir by: 1.

Heterogeneity is often first seen in a review of the histograms of the porosity and permeability data and these should always be part of an initial reservoir analysis. Porosity data tends to form a symmetrical or normal distribution. Permeability on the other hand is often positively skewed, bimodal and usually highly variable (Fig.
