Z-Seal Technology

The Z-Seal is a new type of high-expan- sion, metal-to-metal sealing device that uses expanding metals in place of tradi- tional elastomers to form a high-integrity pressure seal on the tubular wall. The Z-

Seal technology makes well suspensions and interventions possible in hostile

HP/HT environments that were previous- ly deemed inoperable.

Fire Resistant

Cable

When fire breaks out, critical emergency systems must con- tinue to operate. One of the potential weak links in the emergency system is the wire and cable and its ability to withstand the extreme temper- atures. By passing the 1,100oC test, with an energy of more than 200 kW/cu. m., which is above the melting point of the copper conductor found in wires, means that the new Flex-

Flame HC 1100/30 wire and cables are able to keep emergency power, emer- gency pumping systems, emergency sea- water/fire pumping systems and other critical applications in hazardous areas going during the most challenging and dangerous conditions.

Subsea Electric

Actuator System

FMC Technologies' Electric actuator technology is a new technology for actua- tion of subsea valves. The technology offers precise position control and can be applied subsea without hydraulic umbili- cal, providing a huge cost saving poten- tial. Basing the system on local energy storage with rechargeable batteries enables cost efficient retrofit scenarios like the Statoil's Norne system in the

North Sea, where manual and hydraulical- ly operated valves and chokes will be electrically operated. This modification gives better response times for the chokes, enables free routing of existing and new infield wells and it liberates hydraulic lines in an existing umbilical. The lines in the umbilical will now be used for chemi- cal injection fluids, so the need for a new umbilical for the new wells was eliminat- ed and CAPEX for the field extension was reduced significantly.

Pressure Drilling

System

The PowerAMPS Automated Managed

Pressure System, a product developed by the Power Chokes division of PowerWell

Services, addresses many long-standing drilling and wellbore stability-related issues — elimination of pressure surges when stopping/starting circulation, improved drilling fluid management, enhanced ECD control, improved hole conditions, and perhaps most important, the ability to drill more efficiently within narrow pressure environments.

The PowerAMPS System, a continuous circulation variation of MPD technology, is fed data by a hydraulics well-modeling program that reads and processes data, including RPM of the drillstring, ROP, drilling fluid viscosity, density and tem- perature, etc., and then predicts the annu- lar pressure profile. Once the desired pres- sure profile has been determined, Power- 42 • MarineNews • April 2006
