Pascal (unità di misura)
L'unità di misura prende il nome da Blaise Pascal, matematico, fisico e filosofo francese.
In acustica si impiega il Pa o suoi sottomultipli, in meteorologia è più largamente impiegato l'ettopascal (hPa), insieme al kilopascal (kPa). Il megapascal (MPa) e il gigapascal (GPa) rispettivamente per misurare la resistenza dei materiali e il loro modulo di elasticità. (fonte: Wikipedia)
DONGYING, China, Sept. 2, 2014 /PRNewswire/ -- The service of nitrogen production and injection is a measure for an oilfield to increase its production. In Tahe Oilfield, which is located in Xinjiang, China, Kerui Petroleum Equipment Co., Ltd. (hereinafter referred to as "Kerui"), chinese leader of global oilfields comprehensive solution, has achieved another success. Now its overall success rate of nitrogen injection for production improvement is more than 95% and its cumulative production increment is 100,000 tons. According to the features of vuggy carbonate reservoirs at deep layers in Tahe Oilfield, Kerui has adopted its self-developed three-time oil recovery technique based on injection of nitrogen into vuggy reservoirs, and completed the operation of air injection for 115 wells. In operation, while successfully overcoming the challenge of nitrogen injection for wells with the depth of over 7,000 meters, Kerui, again, verified the high quality and high efficiency of the nitrogen...

The turbopumps distinguish themselves with their high pumping speeds, maximum gas throughput and very good compression of light (H2, He) and heavy gases (Ar, CF4). The process equipment is yet another feature making these high vacuum pumps ideal for deployment in the flat and touch panel fields. The suitability for industrial applications is confirmed by the IP 54 protection class and SEMI S2 Standard certification. The functional aluminum housing keeps these pumps extremely lightweight. A sealing gas connection protects the bearings from particles and reactive gases. This results in optimal integration capacity and a significantly improved service life.

Packers Plus worked closely with Geodynamics to design specialized Inferno™ completions equipment capable of withstanding 300°C (600°F) and 69 MPa (10,000 psi) pressure. This equipment was instrumental to the EGS process, which involves stimulating existing fractures in low-permeability, high-temperature rock to allow water to flow through and be superheated. Geoff Ward, CEO of Geodynamics stated, "the willingness of Packers Plus to design and test their equipment to the limit has made them a strategic partner for Geodynamics."
