Onshore/Offshore Hot Tap Services

For onshore and offshore hot tapping capabilities on time and within budget, Cudd offers decades of experience and access to resources for an unparalleled execution.

When conventional pressure relief fails, we can perform a hot tap procedure by drilling a hole in a pipe or tube to gain access to a wellbore if wellhead valves become inoperable.

We are the pioneers of subsea hot tap and valve drilling operations, developing a first-of-its-kind subsea well intervention unit designed to reduce costs and minimize the environmental impact. Our remote-operated tool is rated to work at pressures up to 1,000 psi.

Ultra-Compact Hot Tap Engineered for Rapid Deployment

The only hot tap on the market rated API 6A 3G eases logistics concerns by offering a smaller footprint, yet still delivers the same high-quality performance our customers have come to expect from Cudd. Because of its compact size, the unit can be flown at a moment’s notice on a private aircraft and transported in the bed of a pickup truck to arrive on location for operation when you need it.

Freeze Applications

Freeze Applications

For more than 20 years, our cryogenic and dry ice freeze operations have provided access to critical equipment, onshore and offshore, so that crews can perform maintenance or repairs while the wellbore remains pressurized. Over the years, we have perfected the technique to increase the power of the temporary ice plug, creating a highly functional field tool so that your team keeps cool under pressure.

Staging our unique approach to freeze operations allows for the removal and replacement of faulty equipment with the peace of mind that the plug will hold for the length of time required to properly perform repairs on BOPS, valves, production trees, and other non-cylindrical items.

We also perform cryogenic freeze operations on tubulars of all sizes, successfully plugging through multiple casing and cement layers for a faster freeze that holds longer.

Gate Valve Drilling

Have a pressure control situation that requires a different point of entry? Gate valve drilling offers an effective approach by drilling out an inoperable gate or plug while it’s in the closed position. This is performed while maintaining pressure downstream of the gate or valve.

Doing this allows for accurate monitoring of the pressure, a controlled release of the pressure, or provides the opportunity to pump in fluids to freeze or kill the well. We have the capabilities to drill a gate or TIW valve to its full inner diameter.

For longer reach operations, our pressure-compensated gate valve units can access drilling points several feet away from the unit. Available units deliver up to 15,000-psi pressure ratings in H2S service.
