The method of preparation involves the curing of Pickering water-in-oil medium- or high-internal-phase emulsions containing monomers in the annular space between a rock formation and pipe. 2006).Īs an alternative, this paper presents a pioneering method to prepare void-free and mechanically sound permeable barriers in subterranean formations as an alternative to gravel packing. Bridging of sand particles within the gravel pack can create voids, which can result in mechanical failures or significantly reduce the effectiveness of gravel packs to restrain fines from flowing along with the hydrocarbons produced ( Suman 1974 Tiffin et al. However, gravel packs can be problematic. Unconsolidated fines are highly challenging, as they are expensive to dispose of and can cause erosion of surface equipment, casing failure, clogging of production pipes, and production loss ( Penberthy and Shaughnessy 1992 Sparlin and Hagen 1985). Gravel packing is a well-known technique for sand control, whereby unconsolidated fines produced from the soft formation are filtered away from the production fluids (Penberthy and Shaughnessy 1992 Saucier 1974 Powell et al. Gravel packs, most commonly occurring as sand slurries, are conventionally employed as a permeable solid layer in the annulus between a production screen and walls of the wellbore in weakly consolidated subterranean formations ( Powell et al.
