International audience; We demonstrate that time-domain Brillouin scattering (TDBS), a technique based on an ultrafast pump-probe approach, is sensitive to phase transitions and apply it to the study of structural changes of 8CB liquid crystals at di

Zusammenfassung In der Öl- und Gasproduktion wird nach der Bohrung ein Stahlrohr, genannt Futterrohr, in das mehrere Kilometer tiefe Bohrloch eingeführt und der Ringraum zwischen Rohr und Gestein, genannt Annulus, mit Zement verfüllt. Die vollstä

Acoustic non-destructive evaluation is widely used in the oilfield industry to evaluate the state of the material behind the steel pipes, called casings, which are used in the construction of subterranean oil and gas wells to retrieve hydrocarbons. T

Using a rotating sensor to take acoustic measurements of geological formations from a fluid-filled borehole is common in the oilfield industry. The deployment of ultrasonic devices enables characterizations of the borehole diameter (caliper) and deta

We present results of time-domain Brillouin scattering (TDBS) to determine the local temperature of liquids. TDBS is based on an ultrafast pump-probe technique to determine the light scattering frequency shift caused by the propagation of coherent ac

Leaky ultrasonic Lamb waves propagating in liquid-filled steel pipes are widely used by the oilfield service industry in wellbores to measure the acoustic properties of the material located outside the pipe. Typically, the annular region between the

In the oil and gas industry, the nondestructive evaluation of cemented steel pipes in subterranean wells commonly involves the use of ultrasonic guided Lamb waves. These measurements help determine whether the cement annulus between the rock formatio

In the oilfield industry, subterranean wells are constructed by placing steel tubes, so-called casings, inside the borehole and filling the space between casing and rock with cement. After the cement has cured, its proper placement is often verified
