Abstract:
Reaction products produced by reacting a maleated tall oil fatty acid and/or a maleated soy oil fatty acid with an ethylene amine material are used as clay inhibitors in drilling fluids and in hydraulic fracturing fluids for drilling wells and for fracturing subterranean formations, and are also used as clay inhibitors in other treatment fluids for treating wells or subterranean formations.

Claim (Index 1):
A method of inhibiting clay swelling, the method comprising contacting clay with a water-based fluid that includes an effective amount of a clay swelling inhibitor composition, wherein said clay swelling inhibitor composition is an amine-terminated reaction product that is effective at reducing clay swelling and is produced by reacting a maleated fatty acid material with an ethylene amine material, wherein said maleated fatty acid material is maleated tall oil fatty acid, maleated soy oil fatty acid, or a combination thereof.
