ABSTRACT:
A mobile snubbing system and method of operation transports a snubbing unit to a wellhead on a mobile platform. The snubbing unit is supported by a frame pivotable about a wellhead end of the platform for aligning the snubbing unit with the wellhead. A pipe handler boom is operable between a platform position for loading and off-loading tubulars at an open side of the platform and a second snubbing position for loading and off-loading tubulars at the top end of the snubbing unit. The boom can be telescopic for extending to the top of the snubbing unit and can be automated after learning tubular manipulation at the wellhead. Pipe racks can be deployable from the open side of the platform and an indexer and kicker in the platform enables loading and off-loading tubulars at the pipe handler.
