A frequent challenge encountered in the exploitation of mature gas fields located Getic Depression is sand production. Causes production are mainly related to degree rock consolidation, lithology, increasing water and rates. The effects multiple such us low productivity wells, accumulation into surface equipment, erosion downhole plugging perforation zone casing damage. current paper will addre...

There are multitudinous, multispecies, nonlinearity, multiphase and so on complex system time and space scales characteristics in steel plate production process, whose defects are divided into dominant defects and hidden defects. Real-time dynamic steel plate defects information can not be effectively and quickly converted, it is difficult to find the relationship among defects facts, defects r...

The influence of heat processing conditions on the experimental steel resistance to carbon dioxide corrosion for Fe-V-Si alloying system in a model CO2-containing operating environment, is viewed. Findings alloy structural, mechanical and characteristics, giving that it had new constitution, can be great importance development grades production oilfield casing tubular goods, resistant environment

ABSTRACT The cultivation of button mushroom has reached a high technological level in developed countries and is associated with productivity indices. This involves not only compost production crop management but also the casing layer. Peat been established as one most appropriate materials for due to its excellent properties. However, good-quality peat available all countries, renewable, which...

This study was conducted to evaluate small-scale hot-water postpackaging pasteurization (PPP) as a postlethality (post-cooking) treatment for Listeria monocytogenes on ready-to-eat beef snack sticks and natural-casing wieners. Using a commercially available plastic packaging film specifically designed for PPP applications and 2.8 liters of boiling water (100 degrees C) in a sauce pan on a hot p...

small diameter timbers have many used in wood and paper industries such as veneer and plywood, furniture industry, wood working and their particle for papermaking and particleboard. diameter of small diameter poplar is between 15 to 35 cm and poplar trees are planted in excess of 23 provinces of iran. small diameter poplar are visual graded to lumber of sawmill. since, small diameter poplars ar...

The article discusses the problems associated with metrological support of equipment for geophysical research, issues ensuring uniformity well measurements, creation Russian standards calibrating when determining porosity coefficients and oil, gas, water saturation, parameters defects during cementing technical condition casing strings water-oil-gas flow. creating full-fledged methods measuring...
