The Efficacy and Superiority of the Expert Systems in Reservoir Engineering Decision Making Processes

open access: yesApplied Sciences, 2021
In the process of making a critical decision in reservoir engineering, most of the time we find ourselves in a quandary. Like in any other scientific or technical field, when we find ourselves having to make a critical decision at a juncture, we cannot ...

The analysis of long-term borehole heat exchanger system exploitation

open access: yesComputer Assisted Methods in Engineering and Science, 2017
The key issue in designing borehole heat exchangers (BHE) is the long-term performance of the ground source heat pump (GSHP) systems. The performance directly reflects economic profitability and depends on a large number of parameters including rock ...

Reservoir-engineering shortcuts to adiabaticity

open access: yesPhysical Review Research, 2022
We propose a protocol that achieves fast adiabatic transfer between two orthogonal states of a qubit by coupling with an ancilla. The qubit undergoes Landau-Zener dynamics, whereas the coupling realizes a time-dependent Hamiltonian, which is diagonal in ...

Dynamical decoupling efficiency versus quantum non-Markovianity

open access: yesNew Journal of Physics, 2015
We investigate the relationship between non-Markovianity and the effectiveness of a dynamical decoupling (DD) protocol for qubits undergoing pure dephasing. We consider an exact model in which dephasing arises due to a bosonic environment with a spectral

Localization and further extraction of residual recoverable oil reserves in low-permeability sandstone reservoirs with chaotic oblique layering in a late-stage field: a case study of the Achimov sequence

open access: yesИзвестия высших учебных заведений: Нефть и газ
Achimov sequence is characterized by high heterogeneity and low reservoir properties. Development of Achimov sequence occurs using horizontal wells with multistage hydraulic fracturing.

Application method of determining polymer injection timing with relative permeability curves

open access: yesYouqicang pingjia yu kaifa, 2020
The early polymer injection technology can further improve the polymer flooding effect, and the method to judge the time of polymer transfer by laboratory experiment and numerical simulation is relatively complex and limited in application.
