Major issues contributing to this include the absence of Variable Speed Drives (VSD) and downhole sensors for reliable monitoring, the use of ESP components from various suppliers, an outdated...

... is reliable in every kind of context. The longest mission carried out by the sensor was of 60 km, gathering any kind of information crucial for the pipeline maintenance. The instrument gathers pressure and temperature data which can be linked to specific events inside the pipeline. Also, being equipped...

... assess the VoI for DMs with different attitudes, under different levels of information reliability. We define attitude to be as: neutrality to upsides and downsides, aversion to downside risk, and willingness to exploit upside potential. We applied a simple and flexible formula, which incorporates EMV...

... Abstract There is a potential for improving the reliability of standard core tests for seismic monitoring studies. A primary concern is to quantify and correct for core damage effects, which significantly enhance the stress dependency of wave velocities. Careful laboratory procedures...

... and the filtering considerably improved. l:,he result is a highly reliable and low maintenance hydraulic. The control unit of the oil hydraulics is also located within a sub pocket. Amongst easy maintenance this placement allows a comfortable adjustment of hydraulic pressure just during the final assembly...

... changes. The resultant variation in the Wheatstone Bridge output voltage is converted by the VCO to a frequency change, which is a function of pressure. This gauge is rugged and reliable. However, its long term stability is impaired at temperatures in excess of 100 deg C. In view of this limitation...

... Abstract The design of completions which are effective and reliable is of increasing significance to the viability of both existing and new fields. With greater emphasis being placed on the input of advanced engineering techniques to oilfield developments, the improvement of the completion...
