460k (Stand Alone)


The ISS 340k, 460k & 600k stand alone snubbing units are designed and custom built to perform live or dead well interventions. They have capabilities to run tubing from 2-3/8″ to 10-3/4″ and have 22,000 ft/lbs rotaries that allow them to take on tasks unheard of in the snubbing industry such as drilling, milling out windows for side tracks and side tracking. Stand Alone Snubbing or Hydraulic Workover units are a safe and cost efficient alternative to conventional workover rigs. Cost savings are directly realized through the quick rig up/down & MOB/De-MOB times. In most cases, ISS can workover a well, turn the well back over to production, and De-Mob before a large scale conventional workover rig can even be rigged up on a typical offshore installation.
