Laboratory measurements of the effects of steam injection on the electrical conductivity of sands can aid in the interpretation of electrical surveys used to monitor subsurface steam-injection projects. The effect of variations in injected steam quality was measured in the experiments presented here. The injection of low-quality steam, boiled from a 0.01 mol/L NaCl solution, into clean sand sat...

 Understanding the flow behaviour in a gas well is crucial for future production strategies, obtaining bottomhole conditions from wellhead production data, analyzing production data and estimating reservoir properties. In this work, the pressure profile and flow regime are studied on four wells of a multi-well, multi-layer gas-condensate reservoir, producing at high rate. The wells are deviate...

a proper understanding of reservoir fluid phase behavior is the first crucial step in the development and production of an oil/gas field. this paper addresses the challenges and errors associated with the fluid sampling that may arise before, during and after the sampling operation. for this aim, dst and pvt data of exploration and production wells of a supergiant offshore gas condensate reserv...

The effect of clay content on the electrical response of steamflooded geologic material is studied using a combination of laboratory experiments and numerical simulations. The presence of clay can increase the conductivity of a steam zone by providing a surface conduction path that is enhanced strongly by temperature increases. Clay also increases the residual water saturation in a steam zone, ...

iran's proved natural gas reserves are the world's second largest reserves. mainly, because of different climate changes and different reservoirs characterizations, studying the behavior of producing outcome fluids and their transportation, is of major interest. one of the main problems occur in the gas reservoirs is related to the hydrate formation while producing from a well, either in produc...

Most electric power is produced by steam turbines. This is because the steam cycle is well suited to the conversion of heat to work and steam turbines can be built in a wide range of capacities up to about 1500 MW. Steam turbines are basically very simple having fixed blades to accelerate the steam and moving blades to absorb the resulting kinetic energy. The moving blades are mounted on a rota...

Abstract Steam explosion (STEX) of woody biomass is an efficient pretreatment method in the production water-resistant wood pellets. The STEX process also generates aqueous condensate stream containing dissolved organic compounds, with furfural as most abundant and valuable component. An industrial-scale recovery for other by-products therefore being developed built. One challenge has turned ou...

The commonly used seed spice Cumin (Cuminum cyminum Linn.) contains 3-4% volatile oil and about 15% fixed oil. Conventional grinding of cumin is associated with problems of temperature rise, caking, clogging of sieves and deterioration of quality due to loss of volatiles. Shortcomings of the conventional size reduction were obviated by flaking and the effect of flaking on the yield and quality ...
