A new method for measuring the pressure reflection coefficient in a buffer rod configuration
is presented, together with experimental results for acoustic measurements of the liquid …

From the actual development and testing requirements of horizontal wells in domestic
oilfields, according to the problems that the common sensors have relatively low resolution …

Oil is rich in information about the operating status of machinery and equipment, and oil
condition monitoring is essential for maintaining the safety and reliability of machinery and …

This paper describes the use of a non-intrusive capacitance transducer for the simultaneous
on-line measurement of water and undissolved gas in crude oil. The water concentration of …

For many applications, the detection of water content in an oily base liquid is of crucial
importance. Typical examples are automotive oils, eg engine and transmission oils, where …

In a horizontal well with low flow rate, oil-water two-phase flow is stratified due to gravity. For
measuring water cut accurately in a low-production horizontal well, a novel cylindrical …

The continuing need for in situ measurements of the emulsion layer between crude oil and
water within oil field tanks has initiated experimental and theoretical investigations of …

A combination of ultrasonic transducers operated in continuous mode and a conductance/
capacitance sensor (UTCC) is proposed to estimate the individual flow velocities in oil …

The measurement of water cut in crude oil is an essential procedure in petroleum production
and it is desirable to obtain these data through an automatic and real-time method …

This paper will describe a new and unique instrument to accurately determine the water-cut
of an oil-water emulsion. The basic principle of the measurement is based on a novel …
