Partially aminated acrylic acid grafted activated carbon
as inexpensive shale hydration inhibitor
In this work, we report the preparation of a novel
partially aminated and inexpensive water-soluble acrylic
acid
graftedhttps://ww
w.wyactivatedcarbon.comactivated carbon represented
as C-g-AA-NH2 for efficient inhibition of shale
hydration. The as-prepared C-AA-NH2 was subjected to
Fourier transform infrared spectroscopy (FTIR), Nuclear
magnetic resonance (NMR), and thermal gravimetric
analysis (TGA). This was followed by an evaluation of the
capability of the material to inhibit shale through
various tests including anti-swelling, shale recovery,
and immersion tests. Our results indicated that 2% of C-
g-AA-NH2 drastically reduced water invasion into shale by
combining plugging property of the core-centered carbon
nanoparticles with the inhibition ability of the
partially aminated acrylic acid component by adsorption
on the clay surface through hydrogen bonding.

this manner, the plugging of the pore throat of the
interlayer spacing of the shale formation could easily be
achieved. This approach could significantly control fluid
loss, reduce permeability and filtrate volume of drilling
mud by forming a thin film on the formation surface due
to the nano-nature of the carbon component of the
polymer.
