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...

Abstract Naturally, fractured reservoirs play a considerable part in the study, production, and development of hydrocarbon fields because most Zagros Basin are naturally fractured. Production from those is usually affected by presence system connected fractures. In this Tabnak field on fold–thrust belt at zone Persian plate has been analyzed facies models, folding mechanism analysis to identify...

Résumé. — Une modèle porosité double, permeabilité double est presentée pour la simulation d’un déplacement incompressible miscible dans un mileau poreux naturellement fracturé. L’écoulement des fluides est décrit dans le système des fractures et dans chaque bloc matriciel par une équation elliptique pour la pression et une équation parabolique pour la concentration. L’échange de fluide entre l...

This paper describes the applications of the fractured continuum model to the different enhanced geothermal systems reservoir conditions. The capability of the fractured continuum model to generate fracture characteristics expected in enhanced geothermal systems reservoir environments are demonstrated for single and multiple sets of fractures. Fracture characteristics are defined by fracture st...

As the major field in petroleum reserve growth, fractured-vuggy reservoir is the key research in the future. However, in the development of fracture-cavity reservoir, collapse may occur in karst cave which greatly affects the oil well output. In order to forecast the cave collapse before drilling, this work adopts the method of span dichotomy reduction to determine the critical karst collapse o...

Offset-dependent characteristics of seismic scattering are useful in the interpretation of fractured reservoirs. Synthetic seismograms generated by a 3-D finite difference modeling are used to study elastic wave propagation and scattering in heterogeneous fraetmed reservoirs. We use two models having different background medium properties and different azimuthal AVO responses and build heteroge...

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...

When building a model of a naturally fractured reservoir, it is not sufficient to produce a highly detailed static model, it is also necessary that such a model can be flow simulated so that the production response given by the flow simulator can be compared to production history of the field. The technique that we present here takes a highly detailed static model of fractures, and identifies t...

Abstract Anisotropies exist in many sedimentary rocks, particularly naturally fractured reservoirs, causing horizontal stress anisotropies. Case studies indicate that when a rock formation contains high dip-angle fractures or factures (e.g. bedding planes), it has very distinguished stresses. In these cases, the conventional isotropic method for estimating stresses may give erroneous results. U...
