Abstract
A Blowout Preventer comprising a housing, one or more magnets and a magnetic fluid is described. More particularly, a Magnetorheological Blowout Preventer with a Magnetorheological Ram Head that conforms to virtually any cross sectional shape is described with ultra-reliable termination of natural gas and/or oil effluent flow resulting.
Claims22
A blowout preventer comprising:
- a wellbore conduit portion;
- a magnet set including at least one magnet;
- and
- magnetic fluid;
- wherein:
- the wellbore conduit portion is connectable into fluid communication with a wellbore conduit;
- the wellbore conduit portion and the magnet set are sized, shaped, connected, structured and/or located so that a conduit sealing formation will form when the following two conditions are met:
- (i) the magnet set is configured to generate a magnetic field, and (ii) the magnetic fluid is caused to flow in the wellbore conduit portion.
5 more elements
A device comprising:
- a magnetically pluggable fluid a wellbore conduit portion;
- and
- a magnet set including at least one magnet;
- wherein:
- the wellbore conduit portion is structured, sized and/or shaped to be connected in fluid communication with a wellbore conduit;
- and
- the wellbore conduit portion and the magnet set are sized, shaped, connected, structured and/or located so when the following two conditions are met:
- (i) the magnet set configured to generate a magnetic field, and (ii) magnetically pluggable fluid is caused to flow in the conduit at least in a vicinity of the set of magnet(s), then at least one of the following results will be caused:
- (i) a conduit sealing formation will form in the wellbore conduit portion, and/or (ii) a flow rate of fluid through at least part of the well bore portion will substantially change.
6 more elements
A method for forming a plug in a wellbore conduit, the method comprising the steps of:
- providing a magnet set, including at least one magnet, configured to generate a magnetic field in the vicinity of a kill zone portion of the wellbore conduit portion;
- and
- flowing magnetic fluid through the kill zone so that a conduit sealing formation is formed at least in part by the magnetic action of the magnetic fluid.
