... evaporitic Member of Mrabtine formation. Detailed core study provided better knowledge of its heterogeneous lithology and petrophysical properties, in order to identify the different rock types and evaluate the reservoir potential. In Jeffara Basin, the gross reservoir thickness can reach more than 300 m...

... of this thin oil rim is very challenging due to: 1) complexity of the fluid system (volatile oil, retrograde condensate gas cap gas), 2) complexity of the geology of the field (compartmentalization, fracturing, and rapid lithological variation), 3) high heterogeneity in reservoir properties (permeability...

... heterogeneity and to discuss the parameters that control the vertical and lateral distribution of these facies (sedimentology, diagenesis...). The Lower Silurian "Hot Shales" are highly heterogeneous and exhibit strong vertical and lateral facies variations, which might explain the complex distribution of TOC...

... and interpretation of the mineralogical, lithological and geochemical data indicate significant vertical and lateral heterogeneities, probably induced by local facies changes, which possibly lead to strong variances in the shale gas potential. The properties of the Silurian hot shale samples were compared...

... Abstract Much has been written about carbonate reservoir complexities, heterogeneity, and data integration at different scales. However, there are not many published examples that show a comparison of producibility modeling predictions and actual field results that include data from core...

... Abstract One main challenge in reservoir modeling is the computational costs of flow simulation. Although computer power has significantly increased in the past few decades, effective upscaling to reduce computation time in heterogeneous reservoirs still remains a challenge. This research...

... communication between the injection and production wells as well as an understanding of formation heterogeneity can be of great help to overcome these problems. While techniques such as seismic, mapping geological deposition and reservoir simulation provide valuable information about the feasibility...

... heterogeneity and intercept natural fractures when present in the reservoir. Although the two techniques have significantly improved production from marginal areas, several limitations and problems still have to be addressed. Challenges include weaker-than-expected productivities, rapid production decline...
