Abstract: A tubing hanger retention system for a wellhead assembly can include a retention ring that is configured to fit over a top portion of a tubing hanger of the wellhead assembly, where the retention ring comprises a plurality of retention ring channels. The tubing hanger retention system can also include multiple retention pin receiving features configured to be disposed, at least in part, within multiple tubing spool channels of a tubing spool. The tubing hanger retention system can further include multiple retention pins configured to be received by the retention pin receiving features, where each retention pin includes an engagement feature configured to be received by a retention pin receiving feature to place the retention pin in a captured state, where the engagement feature of each retention pin is further configured to enter into an engaged state with a retention ring channel when the retention pin is moved inward.

Abstract: Sensors may be located remotely from a rig of a well. The sensors may operate independently of the rig, and generate remote sensor information that characterizes operating characteristics of the well independent of the rig. The operation of the well may be analyzed based on the remote sensor information.

Abstract: A system for fracturing multiple wellbores on a multi-well pad can include a missile that receives high-pressure fracturing fluid from a plurality of pump truck. The system can also include a main manifold that receives the high-pressure fracturing fluid from the missile, where the main manifold includes multiple valves and multiple output channels, where each of the valves are operated between an open position and a closed position. The system can further include multiple wellbores including a first wellbore, a second wellbore, and a third wellbore, where the wellbores are connected to the output channels of the main manifold. The valves of the main manifold can be operated to enable simultaneous flow of the high-pressure fracturing fluid to the first wellbore, the second wellbore, and the third wellbore so that the first wellbore, the second wellbore, and the third wellbore are fractured simultaneously.
