Scientific and technological progress over the last century has led to an enormous increase in consumption of minerals, including energy resources. Most exploited oil gas fields are already considerably depleted, so it is necessary search for new hydrocarbon resources, particularly at great depths. Deep drilling plays a special role solving this problem. The article considers world Russian expe...

background: rafsanjan -noogh- anar's plain (54°, 52′- 56°, 34′ longitudinally & 29°, 51′- 31°, 31′ latitudinally) is one of the iran's plains located in sub- basin of daranjir desert. anar's plain is located at the lowest part of rafsanjan -noogh- anar's plain. according to the geological and field studies of the area, the presence of west and east mounts and deposits re­sulting from evaporatio...

Unconventional well technology is often used as one of the most important means to reduce costs and increase efficiency in oil fields. There are many methods for unconventional type optimization, but there relatively few studies on whether suitable reservoir. In this paper, a method matching wells reservoirs established. our method, we first simplify reservoir choose initial types based experie...

Nowadays, it is vital to pay attention more seriously to the urban environmental risks because of its effects on citizens' lives. One of these problems is groundwater pollution which threatens much valuable water resources. Drinking water in Qom City is provided from different resources, such as watersheds and water wells which are located within the city. Although there is a shortage of water ...

Abstract Prediction of the performance oil wells under Cyclic Steam Stimulation (CSS) is challenging in complex and heterogeneous reservoirs, especially with limited data. Analytical numerical simulation models do not usually give accurate predictions such conditions. In this work, a semi-analytical model was developed to determine consistent mathematical relationships between injected steam so...

We propose to perform measurements of the ratio R = σ L /σ T of longitudinal to transverse cross sections in pion electroproduction. Our emphasis will be on measurements in the so-called semi-inclusive deep inelastic scattering region, with extensions into the exclusive region. Whereas inclusive scattering can not distinguish between the quark flavor, there is great promise in flavor decomposit...
