Abstract: A wall of a subterranean reservoir wellbore may be at least partially coated with spheroid magnetic polymers. Alternatively, a downhole fluid having spheroid magnetic polymers may be circulated within the wellbore to at least partially coat the wall of the wellbore with the spheroid magnetic polymers. A magnetic field or electric field may be applied to the wall of the wellbore having the spheroid magnetic polymer coating forming a reversible pseudo-gel to improve hydrocarbon recovery and/or drilling performance by a method, such as but not limited to preventing or inhibiting lost circulation, improving or increasing rate of penetration (ROP), reducing frictional pressure during wellbore construction, preventing or inhibiting corrosion, and combinations thereof.

A magnetic field may be applied to the wall of the wellbore having the magnetic polymer coating for allowing the magnetic polymers to improve hydrocarbon recovery and/or drilling performance by a method, such as but not limited to preventing or inhibiting lost circulation, improving or increasing rate of penetration (ROP), reducing frictional pressure during wellbore construction, preventing or inhibiting corrosion, and combinations thereof.
