Surface-modified biopolymer as an environment-friendly shale inhibitor and swelling control agent

The efficiency of the oil well drilling process primarily depends on the shale inhibition features of the water-based mud (WBM). The current study describes the effect of surface-modified biopolymer swelling control and rheological properties of clay. The cellulose is a biopolymer with a huge surface area, eminent toughness, a prominent number of functional groups, and relatively non-toxic nature. The surface structure of cellulose gives the...
