To better understand the horizontal well transient productivity in bottom-water reservoir with finite water bodies, model for water-body multiple was developed using Green’s function and potential superposition method. Laplace transforms, Fourier of point source, Duhamel principle were used to obtain well, real space obtained by Stehfest numerical inversion The typical pressure response curve d...

The sensitivity of North Atlantic Deep Water formation to variations in mean surface temperature is explored with a meridional-vertical plane ocean model coupled to an energy balance atmosphere. It is found that North Atlantic Deep Water formation is favored by a warm climate, while cold climates are more likely to produce Southern Ocean deep water or deep-decoupling oscillations (when the Sout...

Deep-sea floating platforms are one of the most important large structures for ocean energy exploitation. A new energy-absorbing device named S-shaped Tuned Liquid Column Damper (TLCD) has been invented for the suppression of the horizontal motion and vertical in-plane rotation of a deep-sea floating platform. A conventional tuned liquid column damper has a U-shaped water tunnel to absorb the e...

During the deepwater drilling, complicated gas-liquid-solid multiphase flow will occur if formation gas enters and migrates in wellbore. Through understanding of wellbore behaviors is great importance for blowout prevention well control. Considering dynamic mass heat transfer process caused by alternating ambient temperature field, a model multicomponent fluid deduced developed, including conti...

The theory of electromagnetic induction by motional sources in the ocean is examined from a first principles point of view. The electromagnetic field is expanded mathematically in poloidal and toroidal magnetic modes based on the Helmholtz decomposition. After deriving a set of Green functions for the modes in an unbounded ocean of constant depth and conductivity underlain by an arbitrary one-d...

abstract level of groundwater is decreased which is mainly because, withdrawal of groundwater is increased, because of lack of right management. economics of rural based farming and farming is dependent of water so decreasing of groundwater effects social welfare. in this study decrease of welfare measure by reason of reduction of groundwater level considered. this study investigated the impact...
