Abstract Understanding the fracture patterns of hydrocarbon reservoirs is vital in Zagros area southwest Iran as they are strongly affected by collision Arabian and Iranian plates. It essential to evaluate both primary secondary (fracture) porosity permeability understand fluid dynamics reservoirs. In this study, we adopted an integrated workflow assess influence various sets on heterogeneous c...

gravity drainage is one of the important recovery mechanisms in fractured carbonate and conventional reservoirs. it occurs due to density difference between the gas in fracture and the oil in matrix as well as in conventional tilted reservoirs. oil phase will form films which are produced under gravity forces (film flow). many gas injection experiments have been done on laboratory scales with d...

Block heights and capillary continuity between matrix blocks play paramount role in the sensitivity analysis and therefore the history matching of cumulative oil production and production rate of carbonated fractured reservoirs. In this study, the influence of these parameters upon cumulative production and recovery factor of an Iranian fractured reservoir were studied by the usage of a sim...

Received: January 14, 2017 Revised: April 13, 2017 Accepted: May 15, 2017 Abstract: Introduction: To address reservoir quality assessment in highly complex and heterogeneous carbonate reservoirs, a methodology utilizing fuzzy logic is developed and presented in this paper. Based on carbonate reservoir characteristics, three parameters reflecting the macroscopic and microscopic of storage abunda...

Fractured-vuggy reservoirs are a new target in carbonate oil and gas exploration development. Because of well-developed reservoir bodies, including fractures caverns, bottom water invasion can be observed oilfield development, with low utilization efficiency crude the reservoir. Accordingly, this study focused on intersection region S99 unit Tahe fractured-vuggy reservoirs. Based seismic data, ...

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...

the vapor extraction (vapex) process, a solvent-based enhanced oil recovery process has been found promising for some heavy oil reservoirs. in this work, the vapex process is studied using a compositional simulator on a number of single-block and multiple block fractured systems. pvt data of one of an iranian heavy oil reservoir are used to tune the equation of state. effects of fracture spacin...
