A reliable non-destructive test to assess the integrity of double-cased wells is still an open
task. In the present work, we introduce an analytical–numerical formulation for modelling the …

The integrity of cement used to bond steel casings and formation rock in cased wells is
crucial for the hydraulic isolation of reservoir layers with shallow aquifers, production and …

With the end of oil production, the need for safe and economically efficient plug and
abandonment (P&A) operations increases. Due to the high costs related to traditional P&A …

Ultrasonic pitch-catch measurements are increasingly recognized in cement bond
evaluations for their unique ability to discern between light cement and mud within the …

In the oil and gas industry, pulse echo measurements have for decades been used in cased
holes to estimate the properties of the materials on the outside of the pipe. To investigate the …

A fast method is presented for calculating the wavefields from initialized leaky Lamb waves
on plates immersed in sufficiently light fluids. The method works by precomputing the …

Verification of annular barriers is essential for well integrity, with ultrasonic methods being
central in well integrity testing for many decades. By doing ultrasonic pitch-catch …

Ultrasonic well integrity logging is an important and common procedure for well completion
and plug-and-abandonment operations. Typical logging tools employ single-element …
