A lost circulation material (LCM) having flakes formed from waste vehicle tires. The LCM includes flakes produced from waste vehicle tires processed to remove steel components of the tires and produce flakes having a specific size. Also, methods of lost circulation control and manufacture of the waste vehicle tire LCM.

Spent vehicle tire lost circulation material (LCM)

A retractable and extendable cone-type reamer is positioned on a drill string. An extension and retraction mechanism is configured to extend and retract the cone-type reamer. A hydraulic power unit is configured to control the extension and retraction mechanism. Sensors are positioned on or within the cone-type reamer. The sensors are configured to detect parameters of the wellbore-type hole opening system. A controller is operatively coupled to the hydraulic power unit and the sensors. The controller is configured to be positioned in a wellbore. The controller is configured to receive signals from the sensors. The signals represent the parameters detected by the sensors. The controller is configured to identify the parameters represented by the signals. The controller is configured to adjust a parameter of a wellbore-type hole opening operation in response to the received signals.

A retractable and extendable roller reamer is positioned on a string. The retractable and extendable roller reamer is configured to support and centralize the string within the wellbore. An extension and retraction mechanism is configured to extend and retract the roller reamer. A hydraulic power unit is configured to control the extension and retraction mechanism. Sensors positioned on or within the roller reamer. The sensors are configured to detect parameters of the well-string stabilizing system. A controller is operatively coupled to the hydraulic power unit and the plurality of sensors. The controller is configured to be positioned in a wellbore. The controller is configured to receive signals from the sensors. The signals represent the parameters detected by the sensors. The controller is configured to identify the parameters represented by the signals. The controller is configured to adjust a well-string stabilizing operation in response to the received signals.
