Abstract: The invention relates to a method of hardening a fluid mass in contact with a wall, in a desirable shape. According to the invention, the fluid mass is a magneto-rheological fluid mixture that in addition to at least one hardening component comprises a particulate magnetic component, with minimally 80% of said particles having a particle size of at least 0.0005 mm, and a magnetic field is applied for a length of time that suffices to achieve the desired strength by hardening in the absence of a magnetic field.

Abstract: The invention relates to a method of drilling a bore hole into a stratum, wherein via the drill hole drilling fluid is introduced and fed to the drill head. In order to avoid dilution or leak-off of the drilling fluid the same is in accordance with the invention a magnetorheological drilling fluid, and when an undesirable pressure difference occurs between i) the drilling fluid at the height of the drill head and ii) a fluid present in the stratum surrounding the drill head, a magnetic field is applied. The inventions also provide a permanent solution.

Abstract: The invention relates to a method of winning oil from a source via a bored well, wherein a magnetorheological fluid is introduced into the source via the bored well to re duce the water content of the oil won. Oil drilling is resumed in the presence of a magnetic field, thereby increasing the oil yield and/or decreasing the water content of the drilled oil.
