A wellbore assembly to plug and abandon a wellbore below a setting depth includes a whipstock assembly configured to drill a lateral wellbore from a primary wellbore formed in a subterranean zone. The wellbore assembly includes a tool assembly connected to the whipstock assembly. The tool assembly is configured to be lowered into the primary wellbore during the same trip as the whipstock assembly. The tool assembly is configured to perform wellbore operations downhole of a casing window from which the whipstock assembly is configured to drill the lateral wellbore before the whipstock assembly drills the lateral wellbore.

Whipstock to plug and abandon wellbore below setting depth

An ultrasonic flow check system for wellbores includes an ultrasonic transceiver installed within an inner surface of a bell nipple attached to a well head of a wellbore at a surface. The bell nipple receives wellbore fluid from a flow line attached to a side surface of the bell nipple. An alarm is installed on a rotary table installed above the bell nipple such that the bell nipple is between the rotary table and the well head. A ultrasonic signal is caused to be transmitted, by the ultrasonic transceiver, into the bell nipple. The ultrasonic signal is reflected by the wellbore fluid within the bell nipple resulting in an ultrasonic response signal. The ultrasonic response signal is caused to be received by the ultrasonic transceiver. Based on the ultrasonic response signal, it is determined whether the fluid level within the bell nipple is static or mobile.

Ultrasonic flow check systems for wellbores

A downhole tool includes a tool body including an uphole joint and a downhole joint configured to couple within a wellbore tubing string that extends in a wellbore. One or more flow directing paths are formed on an outer surface of the tool body and configured to rotate a portion of the tool body in response to a fluid flow within the wellbore tubing string. One or more ports are disposed around a circumference of the tool body; and a piston is configured to adjust between an open position such that the one or more ports are open to enable injection of a lost circulation material circulated through the tool body and into the wellbore and a closed position such that the one or more ports are closed to block injection of the lost circulation material into the wellbore from the tool body.
