The main objective in oil production system using gas lift technique is to obtain the optimum gas injection rate which yields the maximum oil production rate. Relationship between gas injection rate and oil production rate is described by a continuous gas lift performance curve (GLPC). Obtaining the optimum gas injection rate is important because excessive gas injection will reduce production r...

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...

biodegradation of petroleum hydrocarbons (20 g/kg dw soil) was investigated in 3 media, differing in the kind of petroleum fractions. in the laboratory experiments, during 5 months, the activities of petroleum hydrocarbon-degrading microorganisms and dehydrogenase activity of soil was determined. gas chromatographic analysis showed the biological decontaminations for gas oil, kerosene and synth...

the purpose of this study is to investigate the role of oil, natural gas and coal consumption in iran’s economic growth during the periods from 1980 to 2012. the stationary analysis is performed by using adf and phillips-perron unit root test and auto-regressive distributed lag (ardl) approach was used to test for co-integration between the variables. the findings show that the variables are co...

Reduction of energy consumption and CO2 emissions are recognized as important issues in today’s world. In addition, oil and gas companies are looking for ways to increase their capacity and maximize system uptime in order to meet the global energy demand. To realize these goals, oil and gas facilities are looking for 261 STUDY OF LARGE VSI DRIVE SYSTEM FOR OIL AND GAS INDUSTRY

Abstract This paper establishes the risk assessment index system according to characteristics of oil and gas drilling engineering cooperation project. After modularizing risk indexes of oil and gas drilling engineering cooperation project into eight clusters, risks are evaluated on the basis of multi-level fuzzy comprehensive evaluation method. The study is to construct risk assessment indexes ...

A new formulation to easy simulation and optimization of gas and oil production systems is presented in this work. The problem of interest corresponds to the typical daily gas and oil production calculation, i.e. a one-day time period planning. The simulation problem considers determination of oil and gas production for the current topology. The optimization problem is established by considerin...

The high-speed swirling flow field in the cyclone oil-gas separator will cause the breakup of oil droplets, thus reducing the separation efficiency. In this paper, the performance of an oil-gas cyclone separator was investigated through both numerical simulations and experiments with considering the breakup of oil droplets in oil-gas cyclone separators. The gas flow field was simulated using th...
