Gas engine introduced to compressor operations
This firm’s 34SG gas engines now are available for gas compressor operations.
With outputs of 4,050-9,000 kw (5,430 to 12,070 bhp), these gas engines are suited for gas pipelines and gas storage.
Three versions are available: the 9-cylinder in-line 9L34SG with 4,050 kw (5,430 bhp) shaft power, the 16-cylinder 16V34SG engine with 7,200 kw (9,655 bhp), and the 20-cylinder 20V34SG with 9,000 kw (12,070 bhp) shaft power. The nominal speed is 750 rpm. Compared with gas turbines often used for driving compressor sets in this power range, 34SG engines offer lower fuel gas consumption and greater turndown ratios, the company says.
Engines have a full-load efficiency of 46.3% (heat rate 5,493 btu/hp-hr), a 30% speed turndown ratio (to 525 rpm), and a 70% torque turndown ratio. Engine efficiency and exhaust emissions remain virtually unchanged on the whole load range. The 34SG engine has low exhaust emissions. NOX emissions remain below the 500 mg/cu Nm dry at 5% O2 level throughout the entire speed and torque range. Engines have a fully electronic control system for all the main engine functions: gas feed, charge airflow, fuel gas flow control, individual cylinders, and ignition control.

New gauge for oil field use
This new oil field safety case gauge features a solid front and blowout back.
The gauge features a 0.5% ANSI/ASME Grade 1A accuracy, full rotary movement and a micrometer pointer for easy calibration. The 4.5 in. dial helps make the gauge easy to read. (Four in. and 6 in. dials are available.)
It’s suited for uses where high pressure buildup may cause ruptures in the bourdon tube. A solid wall separates the tube from the gauge face, thereby forcing the back to blow out in the case of catastrophic failure. Its safety glass lens is shatterproof.

New reservoir engineering software package
Newly released GOCAD Suite Version 2.5.2 is a software package for reservoir engineering and advanced geologic and seismic interpretation.
The suite includes four work flow-based applications for improved functionality and interconnectivity in structural analysis. Version 2.5.2 extends interdisciplinary 3D subsurface modeling with integrated work flows, rigorous data analysis, new documentation, and the addition of plug-in extensions.
