The exploitation of natural gas deposits also requires the transport extracted fluids through pipelines to their treatment facilities. Usually contain, in addition methane, ethane, liquid fractions propane, butane, hexane and sometimes salt water associated with deposit. Given that delivery for consumption must be carried out without oil liquids, flow rates extraction wells are taken two-phase ...

Due to the high energy density, large potential reserves and only release CO 2 water after combustion, natural gas hydrate (NGH) is considered as most likely new clean source replace traditional fossil (crude oil, gas, etc. ). However, unlike exploitation of energy, essence induce production methane by artificially decompose simultaneously collect generated methane. Because uncontrollable decom...

Because some oilfields in China belong to the thin bottom water reservoir model, actual drilling process is technically difficult. In order ensure maximum operation of target layer and basic development effect oilfield, technicians should introduce advanced steering tools study new geosteering technology fundamentally exploitation quality oil reservoirs.After exploring introduction geological g...

With the still huge dependence on crude oil, it is crucial to develop enhanced oil recovery techniques improve reservoir production and lifespan. Carbonate reservoirs constitute over half world's reserves, but they are challenging in terms of due their complex pore network, oil-wet or mixed-wet rocks, harsh conditions temperature salinity. This work offers a significant contribution exploitatio...

introduction ownership is an important element for sustainability development in natural resource management. rangelands vegetations are important factor for produce in traditional herding therefore recognition of different utilization methods and management of this vegetation resource production for animal grazing and rangelands condition is very important. so this research carried out in 2009...
