New miniature flow control valves
These new miniature dual metering flow control valves are suited for liquid handling applications.
The valves can be customized to specific flow requirements. Each is available in 0.187 and 0.281 diameter models, allowing a designer to specify different metered flow rates for the forward and reverse flow directions within a specific range, depending on the model selected.
Units feature a nominal weight of 1.5 g and 5 g, and the metal components of the valves are constructed entirely of stainless steel.

Logging system helps cut uncertainty ahead of the bit
A new logging-while-drilling system acquires and transmits seismic data in real time without interfering with normal drilling operations.
The seismicVISION system delivers traditional borehole-seismic measurements, including checkshot and interval velocity data in real time, to reduce the uncertainty of events ahead of the bit. Seismic waveforms are available in memory.
Drillers can manage seismic uncertainty, the firm points out, helping reduce well costs and improve safety, especially in deep water and other areas with significant seismic uncertainties.
With the checkshot continuously correcting the seismic map, the driller in depth, as well as the geologists and geophysicists in time, can see in real time where they are on the surface seismic map, the company notes.
The firm says its system has been successfully tested in a variety of offshore locations.
One user drilling in the Caspian Sea reduced seismic uncertainty to 30 ft from 2,500 ft to confirm and hit the target location.Another user, drilling in the Gulf of Mexico, used the service to drill within 60 ft of the base of salt and then used the waveforms to look ahead and identify features below the salt.

New products for Gulf of Mexico uses
Three new products available for the Gulf of Mexico oil and gas market include the Quad blowout preventer-lifting system, guillotine saw, and water-based bolting lubricant.
This firm's new Quad system lifts and moves BOP stacks that weigh as much as 344,000 lb and incorporates a 5-1 redundant safety factor.
The guillotine saw enables cutting pipe sizes as large as 32 in.
Water-based bolting lubricant, Water Boy, is a washable thread lubricant allowing for easy removal from the threads when painting, the company notes.

Pump design suits it for higher volumes
This firm's latest pumping unit design features a long stroke length that suits it for higher volumes.
The 57DB-109-54 unit is beam balanced for economy and is available in the standard T-base frameas well asthe new integral wide base frame. The helical geared, double reductionspeed reducer is fully sealed against outside contaminants and is protected with preset pressure relief valves.
All frame bearings have been designed with large internal grease reservoirs for longer life and lower maintenance.

Free brochure discusses bolting method
A new brochure, offered free upon request, discusses in detail how torque and tension are combined in bolting methods.
An independent test report of the method is included.

New flow computer
The new Nova-Flow flow computer is configurable as a rate indicator-totalizer, batch controller, or mass flow computer.
For more advanced applications and options, Nova-Flow has eight expansion slots to accommodate electronic modules, which provide input-ouput and communications options. Users can choose from optional modules to best suit a particular need. Configuration of the basic unit and the modules is implemented using Windows-based software, which is included with the unit.
The unit may be configured to support mass flow and will accommodate inputs from RTDS, temperature transmitters, pressure transducers, and densitometers. The basic unit includes eight additional lines of digital input-output that are configured via software.
