UL certification testing completed on offshore generator
This firm says it has successfully completed Underwriters Laboratories Inc. certification testing on its new 30 kw generator specifically designed for offshore and other hazardous oil and gas operations.
Certification states that the 30 kw unit meets NEC Class I, Division 2, Groups C and D classification where explosive gases may be present under abnormal conditions.
The wellhead-gas fueled microturbine 30R-SD4-ZJXX for hazardous area operating temperature class T2 (300° C.) is protected with Type X pressurization in accordance with NFPA 496.

New cement offers increased heat range
New FlexSTONE HT flexible cement is an extension of the FlexSTONE advanced cement system for permanent zonal isolation of hydrocarbon reservoirs.
The temperature and flexibility range of the set cement system has been increased with the HT formulation, which provides good mechanical properties at temperature ranges of 40-482º F., or 4-250º C. Deeper, hotter, more complex wells can be sealed for life, the firm notes. The advanced cement system is designed in synergy with downhole rock properties and to endure dynamic downhole conditions, such as variable pressures and temperatures.
The company says its CemCRETE family of cements was adapted to create the FlexSTONE HT system, which uses flexible and expansive materials. CemCRETE technology increases the solids content of a slurry using optimized particle-size distribution. With as much as 2% cement expansion, it is possible to prestress FlexSTONE HT cement, enabling the sheath to close a microannulus several hundred microns in size, potentially sealing fluid leak paths.

New pigging system
The new SmartScan tool is a flexible inspection system designed to help in-line corrosion inspection of “unpiggable” pipelines.
The unit’s flexible structure allows it to navigate pipeline diameter variations of 16-20, 20-26, and 24-30 in., respectively. Future generations of SmartScan tools will be able to navigate additional larger and smaller diameter ranges.
Operators also have the option to launch and receive SmartScan without the need for conventional traps via the use of a hot tap.
