Liaohe Oil Field is a low permeability reservoir, formation oil poor, so far taken the field is
ongoing recovery process, but the time of really pumping oil doesn't account for 20% of …

The extraction process of crude oil requires addition of water, resulting in complex
emulsions, in which the phases must be separated before the petrochemical processing …

Condition monitoring of large power transformers is of paramount importance in power
systems. One of the most common indicators of transformer aging is moisture content in oil …

The aim of this study was to assess whether electrical parameters (capacitance and
conductivity) of fresh engine oils—tested over a wide range of measurement voltage …

A water-in-oil monitor has been developed which is suitable for monitoring water content in
older producing fields, water content in the crude from separators, and water content in …

Flow rate measurement in pipes is essential for many applications. Thus, there have been a
variety of flow meters developed that incorporate different technologies. However, a typical …

The properly behavior of power transformers is highly dependent of the insulation health.
So, the insulation condition assessment can provide information to a system of diagnosis …

This chapter highlights a representative example of overall capabilities of ultrasonic wall
thickness monitoring sensors. Ultrasonic thickness gauging is one of the most commonly …

A method based on acoustics to determine, via the speed of ultrasound, the composition and
the pressure of a gas mixture from the outside of the pipe and thus provide an answer to this …

This paper presents an experimental study to investigate the suitability of thick-film ultrasonic
transducers for composition measurements in heterogeneous mixtures. Following on from …
