Lab and Field Scale Modeling of Near Miscible CO2 Injection in Different Porous Mediums [PDF]
Journal of Petroleum Science and Technology, 2015 The main purpose of this investigation is to study the effect of near miscible CO2 injection in different porous mediums on both lab and field scales. This effect can be traced by the change of two-phase gas-oil relative permeability curves. In this work,

Failure analysis of long round thread in horizontal well casing under multi-axis loading [PDF]
E3S Web of Conferences, 2020 The casing is subjected to complicated forces underground, and the threaded joint of the casing is the weak link of the casing. becoming more and more severe, various kinds of failure accidents often occur in practical use.

Quasistates in a ring coupled to a reservoir and their relation to the Dicke effect [PDF]
, 2003 We study the energy spectrum and the persistent current in an ideal one-dimensional mesoscopic ring coupled to an external fermionic reservoir. The contact between ring and reservoir is described by a tunneling operator, which causes an indirect coupling

Conditions for superdecoherence [PDF]
, 2020 Decoherence is the main obstacle to quantum computation. The decoherence rate per qubit is typically assumed to be constant. It is known, however, that quantum registers coupling to a single reservoir can show a decoherence rate per qubit that increases ...

Analytical and numerical investigation of escape rate for a noise driven bath [PDF]
, 2001 We consider a system-reservoir model where the reservoir is modulated by an external noise. Both the internal noise of the reservoir and the external noise are stationary, Gaussian and are characterized by arbitrary decaying correlation functions.

Numerical Investigation of Hydraulic Fracture Propagation Morphology in the Conglomerate Reservoir
Geofluids, 2022 The random distribution of gravels makes the conglomerate reservoir highly heterogeneous. A stress concentration occurs at the gravel-matrix interfaces owing to the embedded gravel and affects the local mechanical response significantly, making it ...
