Petroleum technology HPHT Sensor © 2012, all rights reserved Measures in severe environment The typical conditions of operation of the equipment that characterize petroleum applications are the very high pressure - a few hundred bars on the surface and up from 1000 to 2000 bars at the bottom of Well - the extreme temperature ranges from -40 ° C, as may be encountered near the poles, 200 ° C at the bottom of wells. However, the silicon sensor technologies that are capable to operate reliably under such conditions are not currently available on the market. The development of electronic capable of operating at high temperatures is an important challenge. Indeed, component manufacturers specify a maximum temperature circuits 85 ° C, in some cases up to 125 ° C. The realization of complex electronic boards operating 175 ° C involves a particular technical expertise difficult to develop. Also, fluids in pipelines can be extremely corrosive, with concentrations high sulfuric acid or carbon dioxide. The presence of solid particles in the discharge facilities to submit risk of abrasion or clogging deposits. The conditions of shock and vibration are also extreme. The development of Equipments of measure which can be compatible with all the above constraints, requires expertise in materials, mechanical design and fluid, which is not easily accessible to companies operating in the classic sector. Consequently, a new miniature pressure sensor capable of operating in severe environments is developed, the research and development (invention) of measure equipments is the main axe of our activity..

Petroleum technology HPHT Sensor © 2012, all rights reserved Pressure is the most important parameter to assess and control the oil reserves and gas. Because, the technologies used today for measuring pressure in the drilling industry is very limited (mechanical and quartz technologies). And extreme conditions of temperature and corrosion found at the bottom of the wells, the development of miniaturized measurement systems with a higher level of performance and greater reliability is a critical point for better assessment of reserves into production and optimized. And this new technology requires not only a breakthrough in sensitive elements as well as enhanced integration of electronics to provide digital outputs and the ability to advanced communication (communication of the measures towards the surface). Smart sensors and miniaturized We developed an intelligent Probe and Pressure Sound for operating in severe environments, such as that encountered during drilling, during the start of production and during transport of oil and gas. These micro systems have been built in a miniature size (chip size of the order of a millimeter). They are builds by last advanced technology in microelectronics and micromechanics (MEMS). The MEMS ( Micro-Electro-Mechanical-Systems) is an evolution of the technologies of the microelectronics in which the miniaturized mechanical structures are micro-manufactured in chips in order to add to the power of calculation the capacities of measures and action. These technologies help to make products smaller, more efficient, more integrated functionality, less consummation

Petroleum technology HPHT Sensor © 2012, all rights reserved Advanced communication (communication actions towards the surface) Based on the development of MEMS technology, our sensors are: High-pressure performance superior to existing products on the market Miniature size Digital output Ultra-fast response Reduced manufacturing cost….. These criteria are essential to future performance monitoring tools for drilling, pumping and production.
