As a result of improved drilling and completion techniques, an increasing number of wells worldwide utilize multilateral systems to minimize the number of surface penetrations required to maximize reservoir contact. However, these systems increase th

A one dimensional (1D) model based on plane wave, linear acoustics is formulated. It is used to estimate the two way nonlinear delay, τ, obtained in a plane layer using a dual frequency-band method where two pulses with a large frequency separation

When using ultrasound for detecting low impedance materials on the surface of high impedance materials, a major challenge is the contrast difference between the strong reverberations from the high impedance material and the weak echoes received from
