Abstract During polymer flooding into the reservoir using shear-thinning non-Newtonian fluids, an interface exists between in situ Newtonian crude oil and injected solution. This paper examines application of well test analysis techniques to develop analytical solution non-Newtonian/Newtonian fluids with different flow index composite reservoirs for estimating boundary conditions such reservoir...

Imaging and characterizing fractured shale reservoirs constitute significant challenges. We introduce a workflow and illustrate the application of instantaneous spectral analysis with the aid of a case study on fractured shale reservoirs. With the well log modeling, frequency dependent energy and phase are improved by removing the wavelet overprint. Extracted frequency dependent energy and phas...

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...

in this work, studies of underground gas storage (ugs) were performed on a partially depleted, naturally fractured gas reservoir through compositional simulation. reservoir dynamic model was calibrated by history matching of about 20 years of researvoir production. effects of fracture parameters, i.e. fracture shape factor, fracture permeability and porosity were studied. results showed that di...

Abstract Capillary dominated flow or imbibition—whether spontaneous forced—is an important physical phenomena in understanding the behavior of naturally fractured water-driven reservoirs (NFR’s). When water flows through fractures, it imbibes into matrix and pushes oil out pores due to difference capillary pressure. In this paper, we focus on modeling quantifying recovered from NFR’s imbibition...
