Abstract
Implementations of the present disclosure include a wellbore assembly that includes a wellhead assembly and a plunger. The wellhead assembly is coupled to a wellbore string disposed within a wellbore. The wellhead assembly includes a lubricator, a spring, and a flexible damper. The lubricator defines a tubular housing. The spring is disposed at least partially within and attached to the tubular housing. The spring comprises a first end attached to the tubular housing. The flexible damper is coupled to a second end of the spring opposite the first end. The plunger strikes, as the plunger is lifted from a downhole location of the wellbore to the terranean surface, the flexible damper. The flexible damper deforms, upon impact with the plunger, to dissipate some or all of the kinetic energy of the plunger.
