Electrically activated downhole valve for drilling applications

A method of activating or deactivating a friction-reducing vibration tool for producing axial vibrations in a drill string during a drilling operation, the method comprising:

• detecting a stimulus using a sensor;
• and
• electrically activating or deactivating the friction-reducing vibration tool based on the detected stimulus, wherein the friction-reducing vibration tool is electrically activated or deactivated by a bypass valve in the drill string, and wherein the friction-reducing vibration tool comprises:
• a rotary driving device;
• and
• a rotary valve, the rotary valve comprising:
• a rotary component connected to the rotary driving device, the rotary component having one or more openings, and
• a stationary component with one or more openings, wherein rotation of the rotary component varies alignment of the one or more openings of the rotary component relative to the one or more openings of the stationary component, and
• a bypass passage defining a flow path around or through the rotary valve, and
• wherein the friction-reducing vibration tool is electrically activated or deactivated by varying the flow through the bypass passage.
