Advances in reservoir characterization and modeling have given the industry improved ability to build detailed geological models of petroleum reservoirs. These models are characterized by complex shapes and structures with discontinuous material properties that span many orders of magnitude. Models that represent fractures explicitly as volumetric objects pose a particular challenge to standard...

Fifty years ago Warren and Root have introduced the shape factor. This fundamental parameter for modeling of naturally fractured reservoirs has been discussed stormily ever since. Different definitions for shape factor have been suggested which all of them are heuristically based. Recently, Heinemann and Mittermeir mathematically derived - based on the dual-continuum theorem assuming pseudo-ste...

Analysis of fluid flow in naturally fractured reservoirs (NFRs), as a highly heterogeneous and complex system, requires detailed study the fracture-matrix interactions. The main process movement between fracture matrix is spontaneous imbibition (SI), which can occur co/countercurrent states. In addition, most carbonate rocks are non-water-wet, lead to low oil recovery. Wettability greatly affec...

Naturally fractured gas reservoirs have contributed significantly to global reserves and production. The classical gas-well decline analysis relies largely on Arps’ empirical models, or modern production associating with pseudo-variables. explicit original in place determination methodology is extended from homogeneous reservoir naturally under constant variable bottom-hole pressure conditions ...

Naturally fractured reservoirs are indescribable systems to characterize and difficult produce forecast. For the development of such reservoirs, role naturally forming fractures in different stages needs be recognized, especially for pressure maintenance enhanced oil recovery stages. Recent field carbonate aimed at fracture characterization, modeling, network impact networks on were reviewed. C...

Gas injection into a naturally fractured oil reservoir keeps the pressure and increments initial recovery from reservoir. The main aim of this work was to develop numerical model calculate mass transfer (molecular diffusion convection) between gas injected in fracture residual fluid (gas oil) matrix block. dual continuum is applied describe flow behaviour porous media. Finally, validated by com...
