for this study, asmari (oligo-miocene) and bangestan (cretaceous) reservoir oils from themarun oilfield were studied geochemically. gas chromatograms and stable isotopes of carbon and sulfur indifferent oil fractions were studied. normal alkanes nc15+ are as high as 93% with a saturate percentage up to53.9% which reveal a high maturity of asmari and bangestan reservoir paraffinic oils. carbon p...

background: iran is located in the seventh rank in terms of co2 emissions resulting from the fuel combustion in the world. gas compressor booster stations, due to the several sources of contaminants, are causing the release of large amounts of co2 and ch4, which will cause climate change therefore, estimating the emissions of the gases from oil and gas, different processing units are necessary....

Hydraulic fracturing and matrix stimulation are two major methods of the reservoir stimulation. Hydraulic fracturing, which is the newest technique and technically more complex, is very useful in low permeability reservoirs. Although it has been used widely in hydrocarbon production wells, it is a new method in Iran. In this paper, the effect of sufficient barrier layers on hydraulic fracturing...

The the Middle Cretaceous-Lower Miocene petroleum system of the Kupal oil field, located in the Dezful Embayment has been studied. The Kazhdumi and Pabdeh are main source rocks, the Sarvak, Ilam and Asmari formations are reservoir and the Gachsaran formation is the seal rock. According to geochemical analysis the Kazhdumi and Pabdeh contributed to oil production and feeding the Asmari and Bange...

Permeability is the key parameter of the reservoir and has a significant impact on petroleum fields operations and reservoir management. In most reservoirs, permeability measurements are rare and therefore permeability must be measured in the laboratory from reservoir core samples or evaluated from well test data. However, core analysis and well test data are usually only available from a few w...

A new chemical compound is developed at Petroleum University of Technology to enhance the recovery of the free imbibition process and simultaneously hinder asphaltene precipitation. The compound is tested on heavy oil samples from Marun oil field, Bangestan reservoir. The effects of the chemical compound on viscosity, hydrocarbon composition, and average molecular weight of the heavy oil are in...

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...
