the experimental study and modeling of gravity drainage during water alternative gas injection, wag process, in carbonate rock for one of the iranian off-shore reservoir at lab-scale were carried out. the mechanism of gravity drainage during the wag process, and its contribution to the oil recovery in the fractured carbonate reservoirs were also studied. in the wag process alternatively gas is ...

A typical Iranian carbonate matrix block surrounded by an open fracture was modeled in order to understand the fracture-matrix interaction and realize how to model the interaction best. The modeling was carried out by using a fine-scaled Eclipse model in the single porosity mode (the fractures were explicitly modeled). The model was extended to a stack of 6 matrix blocks to understand block-to-...

qareh qeshlaq marble quarry as one of the valuable resources of ornamental stones in west azarbaijan province formed through thermal carbonate springs while its mineral deposit thickness is limited in comparison with surface extension. in the present research, geological and blocky modeling of the marble deposit was carried out in order to develop a production planning for this quarry, identify...

a typical iranians carbonate matrix block surrounded by an open fracture was modelled in order to understand the fracture-matrix interaction and how to model the interaction best. this was modelled by using a fine-scaled eclipse model in the single porosity mode . the model was extended to a stack of 6 matrix blocks to understand block-to-block interaction under gas injection scenarios. results...

in this paper, a very efficient method, called single matrix block analyzer (smba), has been developed to determine relative permeability and capillary pressure curves from spontaneous imbibition (si) data. smba mimics realistically the si tests by appropriate boundary conditions modeling. in the proposed method, a cuboid with an identical core plug height is considered. the equal dimensions of...

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...

Two types of rod-coil block copolymers including poly(3-hexylthiophene)-block-poly(ethylene glycol) (P3HT-b-PEG) and PEG-block-polyaniline (PANI) were synthesized using Grignard metathesis polymerization, Suzuki coupling, and interfacial polymerization. Afterward, two types of single crystals were grown by self-seeding methodology to investigate the coily and rod blocks in grafted brushes and o...
