Abstract Injection of imbibition fluids or CO2 during hydraulic fracturing is an effective stimulation method for tight oil reservoirs. Selecting appropriate agents significant to optimize the integrated scheme and production in In this study, a series lab experiments, including spontaneous imbibition, dynamic huff puff, were carried out using real cores, water absorption apparatus, core floodi...

The integrated injection-production string is the core tool used in thermal recovery wells for heavy oil, mechanical behavior of which complex due to coupling effect downhole temperature and pressure load induced by steam huff puff operations. In this paper, an analysis model that calculates field during operations has been established based on basic principles energy conservation heat transfer...
