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...

avo analysis is a technique which is widely used in industry and is applied on seismic prestack data. results from changes in seismic wave reflection amplitude versus offset can be used in extracting elastic properties and hence lithology and reservoirs pore fluid identification. before performing avo analysis studies, processing steps should be ensured that changes in reflection amplitude are ...

since the pressure of hydrocarbon reservoirs drops due to production, in order to keep the production rate constant or increase enhanced recovery, few methods are used. one of which is gas injection to the reservoir. on the other hand, due to reduction in oil production potential of aghajari oil field, gas injection is highly required to pressurize and enhance oil recovery. there is a possibili...

The purpose of mathematical reservoir simulation models in petroleum applications is to try to optimize the recovery of hydrocarbon from permeable underground reservoirs. To accomplish this, one must be able to predict the performance of the reservoir under various production schemes. There are two essential issues, modeling and software architecture design, while developing a comprehensive oil...

Hydrocarbon production from unconventional resources and the use of reservoir stimulation techniques, such as hydraulic fracturing, has grown explosively over the last decade. However, concerns have arisen that reservoir stimulation creates significant environmental threats through the creation of permeable pathways connecting the stimulated reservoir with shallower freshwater aquifers, thus re...

The methanogenic biodegradation of crude oil is an important process occurring in petroleum reservoirs and other oil-containing environments such as contaminated aquifers. In this process, syntrophic bacteria degrade hydrocarbon substrates to products such as acetate, and/or H2 and CO2 that are then used by methanogens to produce methane in a thermodynamically dependent manner. We enriched a me...

This study developed a novel C-sharp (C#) programming language for the estimation of bubble point pressure (BPP) various hydrocarbon mixtures at equilibrium state. The methodology was based on vapor–liquid calculation using Peng Robinson equation state implementation, thermodynamic and Newton-Raphson’s method successive substitution unknown variables. equal fugacity constraint can be satisfied ...
