Abstract
Treatment fluids that include magnetic surfactants may be useful in various subterranean operations, e.g., particulate placement operations and drilling operations. For example, some methods may include introducing a treatment fluid into a wellbore penetrating a subterranean formation, the treatment fluid including at least a base fluid and a magnetic surfactant, the magnetic surfactant being a cationic surfactant having a magnetically susceptible counterion.
Claims18
A method comprising:
- providing a treatment fluid comprising a base fluid and a magnetic surfactant, the magnetic surfactant comprising a cationic surfactant having a magnetically susceptible counterion, wherein the magnetically susceptible counterion comprises at least one anion of the group of dysprosium chloride, dysprosium sulfide, erbium sulfide, and any derivative thereof;
- and
- introducing the treatment fluid into a wellbore penetrating a subterranean formation;
- and
- applying a magnetic field to the treatment fluid so as to increase a viscosity of the treatment fluid at a location outside the wellbore.

A method comprising:
- providing a treatment fluid comprising a base fluid and a magnetic surfactant, the magnetic surfactant comprising a cationic surfactant having a magnetically susceptible counterion, wherein the magnetically susceptible counterion comprises at least one anion of the group of dysprosium chloride, dysprosium sulfide, erbium sulfide, and any derivative thereof;
- and
- separating at least some of the magnetic surfactant from the treatment fluid using a magnetic field.
A method comprising:
- providing a treatment fluid comprising a base fluid, a magnetic surfactant, and a magneto-rheological particulate, the magnetic surfactant comprising a cationic surfactant having a magnetically susceptible counterion, wherein the magnetically susceptible counterion comprises at least one anion of the group of dysprosium chloride, dysprosium sulfide, erbium sulfide, and any derivative thereof;
- and
- introducing the treatment fluid into a wellbore penetrating a subterranean formation.
A method comprising:
- providing a treatment fluid comprising a base fluid and a magneto-rheological particulate, the magnetic surfactant comprising a cationic surfactant having a magnetically susceptible counterion, wherein the magnetically susceptible counterion comprises at least one anion of the group of dysprosium chloride, dysprosium sulfide, erbium sulfide, and any derivative thereof, wherein the treatment fluid is an emulsion;
- introducing the treatment fluid into a wellbore penetrating a subterranean formation;
- and
- separating a discontinuous phase of the treatment fluid from a continuous phase of the treatment fluid using a magnetic field.
