Abstract
An electromagnetic valving system includes a manifold having one or more flow passages therein; a sleeve disposed relative to the manifold so that movement of the sleeve inhibits or allows fluid flow relative to the manifold; and an electromagnet positioned relative to the sleeve such that a magnetic field generated by the at least one electromagnet produces a motive force in the sleeve and method.
Claims20
An electromagnetic valving system comprising:
- a manifold having one or more flow passages therein;
- a sleeve disposed relative to the manifold so that movement of the sleeve inhibits or allows fluid flow relative to the manifold;
- and
- an electromagnet positioned relative to the sleeve such that a magnetic field generated by the at least one electromagnet produces a motive force in the sleeve.
1 more element
A method for configuring fluid flow in a wellbore comprising:
- selecting a current polarity for an electromagnet in motive force generating communication with a moveable sleeve of a valving arrangement;
- and urging the sleeve to a selected position that facilitates or inhibits flow.
