In recent years, many trials have been made to use the Rate Transient Analysis (RTA) techniques as a method describe gas condensate reservoirs. The problem with using these is multi-phase behavior of Therefore, Pressure (PTA) commonly used in this case analyze reservoir parameters. paper, we are going compare results both PTA and RTA three wells comparison showed great match between two mention...

A Bose gas in a double-well potential, exhibiting a true Bose-Einstein condensate (BEC) amplitude and initially performing Josephson oscillations, is a prototype of an isolated, nonequilibrium many-body system. We investigate the quasiparticle (QP) creation and thermalization dynamics of this system by solving the time-dependent Keldysh-Bogoliubov equations. We find avalanchelike QP creation du...

Weiyuan gas field, located in the Sichuan basin of south China, is a large marine gas field with the oldest reservoir (the Sinian sequences) in south China. The hydrocarbon origin of the gas field has long been debated by petroleum geologists. Recently, it was recognized that a paleo-oil pool maybe the significant contributor to the gas field. Consequently, when the paleo-oil pool had been crac...

The characterization of the gas condensate reservoir is complicated due to multiphase flow fluid. change composition excellent stream further makes it complicated. Such being done measure superb performance. To overcome this complexity, rigorous mathematical modelling suggested for well test analysis. This can be used establish correlation between analysis and performance research work carried ...

Damping in a dilute Bose gas is investigated using a mean-field approximation which describes the coupled oscillations of condensate and non-condensate atoms in the collisionless regime. Explicit results for both Landau and Beliaev damping rates are given for non-uniform gases. In the case of uniform systems we obtain results for the damping of phonons both at zero and finite temperature. The i...

We investigate an optically trapped exciton-polariton condensate and observe temporal coherence beyond 1~ns duration. Due to the reduction of spatial overlap with thermal reservoir excitons, time is more than order magnitude longer that untrapped condensate. This ultralong enables high precision spectroscopy condensate, we periodic beats field correlation function due a fine energy splitting tw...

We show that in an atomic Bose gas near a Feshbach resonance a quantum phase transition occurs between a phase with only a molecular Bose-Einstein condensate and a phase with both an atomic and a molecular Bose-Einstein condensate. We show that the transition is characterized by an Ising order parameter. We also determine the phase diagram of the gas as a function of magnetic field and temperat...

At present, adaptive inflow control (AICD) water-controlled completion technology is mainly applied to reservoir water control. In view of the gas AICD research still blank, this paper carried out a suitable for mechanism new type runner and flow characteristics analysis, X oilfield bottom established port completion. The structure parameter combination was analyzed optimized by orthogonal test...
