..., development and laboratory testing of a novel steam quality sensor, a tuning fork densitometer, are presented. This non-nuclear density sensor technology is adaptable to high temperature operation and has high sensitivity, making it ideally suited to measuring the small changes in density that occur due...

... Abstract As the number of sensors deployed in the oilfield increases, there is a corresponding need to develop methods for fast, automated processing of large-scale sensor data streams. This problem is aggravated when the streams of sensor data are from multiple sensors with different...

The effects of complex characteristics cause sensors to generate a great dynamic error which will accumulate gradually during attitude resolving, so ultimately measuring spatial...

... sensors have been developed that use distributed probes to directly detect hydrocarbons and provide images of the flow profile. The FloView * , PSP, and GHOST * tools have been used in the Monterey to provide accurate profile data necessary for successful workover efforts. When these data are combined...

...Multiparameter Optical Fiber Sensor Implementation We have designed and assembled an optical fiber-based sensor system for the measurement of temperature, pressure, steam quality and steam flow, and have tested it downhole in a steam injection oil well. The sensor package, shown in Figure 1...

... and down-hole vortex shedding sensors combine to measure both flow rate and steam quality parameters. While the signals measured by down-hole vortex shedding sensors are frequency signals, the signals measured by throttling elements are pressures drop. So they are two kinds measuring elements...
