+ Hydraulic Workover/Snubbing:
Onshore & Offshore Hydraulic Workover/ Snubbing Applications covers:
  • Washing sand clean outs
  • Drillout cementing and bridge plugs
  • Fishing lost tools out of tubing and casing
  • Pumping acid
  • Through tubing gravel pack
  • Running and pulling completion equipment (single & dual)
  • Spotting cement and squeezing
  • Change out ESP (electrical submersible pump)
  • Assisting drilling rigs and conventional Workover rigs in trouble - Startup well with natural gas, instead of nitrogen
  • Setting packer
  • Gravel packing
  • Side track drilling
  • Well plugged and abandoned
+ Hottapping
Hot Tap Service allows tapping or drilling entry ports into tubular goods, pipelines or flowlines.
  • Blockage is located and tubing is lifted until blockage is clear of well
  • A Hot Tap clamp is secured on the tubing below the blockage and above the next coupling
  • A full opening valve is attached to the Hot Tap clamp
  • A drill is installed and the distance from fully retracted to extended touching tubing is measured
  • The drill, valve and clamp assemblies are pressure tested to a minimum of 1.5 times the anticipated pressure or up to the maximum working pressure of the equipment being used
  • The pressure on the drill is decreased to slightly less than anticipated tubing pressure. During this procedure, an increase in pressure on the drill side indicates penetration
  • Once the hole is drilled, the shaft of the drill is retracted past the valve allowing the valve to close. The pressure is then bled off from the bit chamber allowing the drill to be removed
  • Pumping, freeze or depressurization operations can commence
+ Gate Valve Drilling :
Gate Valve Drilling Service is typically used to drill out gate valves or plug valves that have malfunctioned and remained in the closed or partially closed position under pressure. Gate Valve Drilling tool can be safely operated under live well conditions, H2S environments, and in pressure up to 15,000 psi or temperatures ranging from 00F to 2500 F.
  • Gate Valve Drilling suited for land based as well as off-shore operations.
  • When rigged up and tested, the entire drilling operation can be performed from the ground. The gate valve drilling unit can be rigged up or down in less than 1 hour in most cases
  • The Gate-Valve Drilling tool is sufficiently durable to drill valves that were coated with tough anticorrosion materials, such as Nickel plated, Stainless Steel, Monel Steel, Inconel Steel, and Stelite that are hard faced. The choke and kill spool incorporated on the pneumatic unit is able to immediately kill or start the well bleed off
  • Capable of drilling, milling, and/or cutting inoperative valves.
+ Freezing/Pressure Control:
Freeze services are typically used to place a temporary barrier (ice plug) in a tubular or vessel in order to maintain pressure control while allowing for safe mechanical repairs to be addressed involving possible valve replacement and general pipe work modifications. The freezing of wellheads and other pressure containing equipment is a time honored procedure which has proven itself as an inexpensive and safe alternative in well maintenance, and in some cases emergency situations. It is a reliable method to control pressures with introduced primary and secondary barriers to facilitate the removal/replacement of wellhead, pipeline, BOPs and other auxiliary equipment which otherwise would, in some instances, be impossible to remove or repair safely. Freezing techniques have been successfully used in situations where the pressures have exceeded 10,000 Psi [70 Mpa/680 Bar]

Procedure:
Through the utilization of liquid N2 and liquid CO2 along with state of the art temperature monitors, costly fluid kills no longer have to be performed and downtime is minimized. With a sufficient supply of the N2 or CO2 on hand and the ability to monitor the freeze process accurately in real time, freeze plugs can be installed and maintained indefinitely in a safe and controlled manner.
