Ultrasonic velocity tomography of rock sample

Rock samples may be analyzed using high-resolution elastography to learn more about fluid movement and stress changes inside rocks. The creation of novel rock core acoustic measurement techniques will also contribute to a deeper comprehension of reservoir geomechanics characteristics. Currently. By quantitatively characterizing the link between rock elasticity and reservoir physical parameters using high-resolution photography of the actual rock core pore structure and numerical modeling. Digital rock physics successfully overcomes the drawbacks of conventional rock physics techniques. The skeleton and the pores are the only components of the core that are separated in the typical digital core study. It makes it hard to portray the rock sample's elastic properties as well as the genuine structure and material composition of the core. In this context, more practical elastic parameter imaging technologies must be taken into account. The elastic characteristics of rock samples may be precisely characterized using ultrasonic tomography technology, which can also be utilized to find interior flaws or heterogeneity. Full waveform inversion, nevertheless, has lately attracted more attention. We can build a more accurate "elastic parameter model of rock samples" using all the waveform data.
