... imbibition is the main mechanism by which fracture fluid enters the rock. Herein we study the spontaneous imbibition of brine to determine the flow mechanism and uptake capability of fracturing fluid in unconventional source rocks. We used NMR spectroscopy and imaging methods to track the spatial...

.... Cationic dodecyltrimethylammonium bromide increases fracturing fluid loss by 46% for the studied Montney sample. Using resulted in better upscaling outcomes compared to and for the studied Montney samples. Pore-scale wettability is required to upscale spontaneous imbibition data from core plug to reservoir...

... limestone cores by water imbibition at 347 K. Results of the contact-angle experiment show that the contact angle was rapidly reduced to 26° with 3pRB, in contrast to the contact angle of 123° with RB, without affecting the oil/brine IFT. Spontaneous imbibition results show that the oil recovery factor...

In addition, as most current studies focused on the spontaneous imbibition under atmospheric pressure, it is important to investigate the process with external pressures because hydraulic fracturing is a high-pressure driven operation. By performing both...

Since 2009, our research group has focused on an idea of using surfactant spontaneous imbibition to enhance the oil recovery from the Bakken Formation, and this idea has been already put in use for a field application test. Our previous work showed that with optimized surfactant formulations...
