“…Cocurrent spontaneous imbibition (COCSI) occurs when only a portion of the permeable surfaces is in contact with wetting phase and the remaining permeable surfaces are covered by nonwetting phase. The main factors controlling the type of process are the degree of fracturing (Qasem et al, 2008), strength of gravitational forces (Schechter et al, 1994), relative position of matrix blocks respect to the source of wetting phase (i.e., injection wells or aquifer) (Standnes, 2004), and injection rate of wetting phase into the fracture network (Pooladi-Darvish and Firoozabadi, 2000b).…”

“…This implies that in the experimental setup, the matrix surfaces covered by wetting and nonwetting phases do not change during the process. There are other cases in which the recovery performance of a matrix block or a stack of matrix blocks under advancing wetting phase level in the fracture system has been studied (Parsons and Chaney, 1966;Pooladi-Darvish and Firoozabadi, 2000b;Karimaie et al, 2006;Karimaie and Torsaeter, 2007;Qasem et al, 2008;Andersen et al, 2014).…”

Abstract:A large amount of liquid is pumped into the shale gas reservoir during hydraulic fracturing, and the fluid flowback ratio is usually low. However, field experience showed that the liquids did not cause severe damage to shale gas reservoir. It is urgent to clarify the water block unlocking mechanism of a shale gas reservoir. This work is to discuss the water block unlocking mechanism in shale gas reservoir. Based on the characteristic study of shale gas formation, the fracturing fluid absorption mechanism, absorption ability and impact on shale gas formation damage are systematically studied. Study shows that ultra-low water saturation, abundant micro-to nano-tubulars and a huge contact area are the control factors for strong fluid absorption ability of gas-shale. The strong water absorption capacity of the shale gas formation matrix is a key factor in removing water block. Organic matter also has an important influence on absorption ability and gas production. A conceptual evaluation criterion for water block unlocking is proposed based on core absorption capacity, original water saturation and fracture density. The shut-in after hydraulic fracturing is beneficial to gas production and can reduce water production for certain shale gas reservoir.

“…The network of fractures can be a continuous flow path throughout the reservoir (Saidi, 1983). Moreover, fractures with different geometries and scales may be present in the network (Wu et al, 2004;Gasem et al, 2008). Various models in the literature show the means of estimating the petrophysical properties of NFRs.…”

Résumé -Inondation chimique dans les réservoirs naturellement fracturés : aspects fondamentaux et pratiques de plein champ -Des méthodes appropriées devraient être utilisées pour augmenter la récupération d'huile des réservoirs naturellement fracturés (RNFs). Un des candidats pour augmenter cette récupération d'huile de ces réservoirs est l'injection d'eau contenant des agents chimiques. Cet article met en lumière les résultats techniques et les défis de cette technique. La classification, les caractéristiques de production, les mécanismes de rétablissement du RNFs et les résultats significatifs de l'injection d'eau contenant des agents chimiques dans ces réservoirs sont passés en revue et analysés. Ce papier vise à être un outil de référence utile aux ingénieurs intéressés par l'injection d'eau contenant des agents chimiques dans les RNFs. Abstract -Chemical Flooding in Naturally Fractured
