We discuss the recently developed bosonic dynamical mean-field theory (B-DMFT) framework, which maps a bosonic lattice model onto the selfconsistent solution of a bosonic impurity model with coupling to a reservoir of normal and condensed bosons. The effective impurity action is derived in several ways: (i) as an approximation to the kinetic energy functional of the lattice problem, (ii) using ...

The phase state prediction methods of condensate gas are relatively mature, but the effect changes on gas–liquid mixture flow behavior and liquid-carrying capacity has not been researched in detail. This study applied PIPESIM software to predict fluid properties under different development stages a reservoir Shengli Oilfield determined diagram physical well stream basis optimized equation (EOS)...

Fluid velocity has the potential to cause severe erosion damage to oil & gas production infrastructure. In order to avoid or alleviate damage due to erosion, the American Petroleum Institute Recommended Practice (API RP) 14E recommends a threshold fluid velocity for production tubing and pipelines. However, field and laboratory data have proven that the applied empirical constants, known as C-f...

We investigate the effect of losses on an interacting quantum gas. show that, for gases in dimension higher than one, assuming together a vanishing correlation time reservoir where dissipation occurs, and contact interactions leads to divergence energy increase rate. This is combined interactions, which impart arbitrary large momenta atoms, infinite width associated its time. how regularized wh...

Production of gases from gas-condensate reservoirs are known to bear certain challenges largely due to the formation of retrograde condensates that hinder gas flow. The drop out of this liquid creates flow regions that are characterized by the liquid saturation as it affects the mobility of the two phase flow, thereby preventing the effective modeling of well productivity. In this study, a pred...

We propose a quantum tweezer for extracting a desired number of neutral atoms from a reservoir. A trapped Bose-Einstein condensate is used as the reservoir, taking advantage of its coherent nature, which can guarantee a constant outcome. The tweezer is an attractive quantum dot, which may be generated by red-detuned laser light. By moving at certain speeds, the dot can extract a desired number ...

Building upon the foundation of the prior investigations, a three-fold classification of tight gas reservoirs is proposed in this paper which is based primarily on dynamic relationship between gas charging history and reservoir tightening process, coupled with tectonic evolution, source-reservoir relationship, migration and charging pattern. The three categories of tight gas are: (1) “pre-exist...

Cyclic solvent injection, known as huff-n-puff, is one of the promising techniques for enhancing oil recovery from shale reservoirs. This study investigates huff-n-puff performance in ultratight reservoirs by conducting large-scale numerical simulations a wide range reservoir fluid types (retrograde condensate, volatile oil, and black oil) different injection gases (CO2, C2H6, C3H8).
