Abstract After single-gas (SG) injection operations in tight oil reservoirs, a significant amount of is still unrecovered. To increase productivity, several sequencing gas techniques have been utilized. Given the scarcity research on multiple-gas alternating schemes, this study propose an optimized triple-alternating-gas (TAG) for improved recovery. The performance TAG process was demonstrated ...

Triple arrays are considered in which 10 symbols each appear 3 times in a 5 × 6 arrangement of symbols. These triple arrays fall into seven isomorphism classes. The orders of the automorphism groups of the arrays in these classes are 60, 12, 12, 6, 4, 3 and 3, respectively. © 2005 Elsevier B.V. All rights reserved.

This research paper describes key information technology (IT) project management activities in terms of project scope, time, and cost management, namely the triple constraint. The authors contend that the ability to properly manage and execute these activities are the quintessential components that oftentimes drives whether projects succeed or fail. The literature shows that IT projects have a ...

this study focused on triple-negative breast cancer (tnbc) that is characterized by the lack of expression of estrogen receptor (er), progesterone receptor (pr), and human epidermal growth factor receptor 2 (her-2). the primary goal of this study was to describe the relation between triple-negative receptor status and survival. this is the first study about triple-negative breast cancer in our ...

on the onset of triple-diffusive convection in a horizontal layer of nanofluid heated from below and salted from above and below is studied both analytically and numerically. the effects of thermophoresis and brownian diffusion parameters are also introduced through buongiorno model in the governing equations. by using linear stability analysis based on perturbation theory and applying normal m...

peripherally inserted venous ports fracture with embolization in patients who received chemotherapy is a serious and rare complication,and few cases have been reported in children. we report a successful endovascular technique using a snare for retrieving broken peripherally inserted venous ports in a child for chemotherapy. catheter fragments may cause complications such as cardiac perforation...

In a triple-hole system comprising primary hole and two sister holes, when the holes are positioned slightly downstream of main under steady flow conditions, their jets generate an anti-counter-rotating vortex pair. Vortex interactions between increase effectiveness adiabatic film cooling. this study, series large-eddy simulations were conducted to understand how pulsations in affect cooling tr...

A phenomenology of isotropic magnetohydrodynamic (MHD) turbulence subject to both rotation and applied magnetic field is presented. It is assumed that the triple correlation decay time is the shortest between the eddy turn-over time and the ones associated to the rotating frequency and the Alfvén wave period. For Pm=1 it leads to four kinds of piecewise spectra, depending on four parameters: in...
