ABSTRACT
The rapid population growth in combination with increasing prosperity in developing countries is expected to lead to a surge in energy consumption over the coming decades. Besides the sensor developments, the interrogator development has a special place in the industry as often the off-the-shelf solutions do not give the required solution, for example, Fiber Bragg grating interrogator development to achieve higher strain resolution or truly distributed systems to achieve unique measurements along the whole length of the fiber. Most permanent sensors in the oil industry are deployed inside boreholes. Once the data are available in the database, various people, such as production technologists, petrophysicists, reservoir engineers, geologists, and seismologists, can access the data and use them for further processing using specialized software. One of the longest standing measurements in the oil industry is the pressure measurement. The fluid level in observation wells is related to the oil rim in reservoir.
