Abstract: Magnetorheological fluids may regulate fluid flow downhole by forming a fluid seal using a bridge plug apparatus. Bridge plug apparatuses employing a magnetorheological fluid may be deployed in a wellbore in a retrievable configuration or in a substantially permanent configuration. Retrievable bridge plug apparatuses may comprise spaced apart magnets having a gap defined therebetween, and a reservoir of magnetorheological fluid housed within the gap. The magnets move laterally with respect to one another to expand or contract the gap and to displace the reservoir of magnetorheological fluid radially with respect to the magnets. Other bridge plug apparatuses may comprise a flow path extending between a reservoir of magnetorheological fluid and the exterior of a housing, where at least a portion of the flow path is located within a gap defined between spaced apart magnets.

The computing system determines based on the geometric characteristics of the well tool and the well, a predicted reaction force on a portion of the well tool that affects operation of the well tool in applying force to the device. The predicted reaction force is due to contact between a surface associated with the well tool and a surface of the well.
