Analysis of outer-casing echoes in simulations of ultrasonic pulse-echo through-tubing logging
Viggen, Erlend Magnus; Johansen, Tonni Franke; Merciu, Ioan Alexandru (Journal article, 2016)Cased petroleum wells must be logged to determine the bonding and hydraulic isolation properties of the cement. Ultrasonic logging of single casings has been widely studied and is commercially available. However, ultrasonic ... -
Simulation and inversion of ultrasonic pitch-catch through-tubing well logging with an array of receivers
Viggen, Erlend Magnus; Johansen, Tonni Franke; Merciu, Ioan Alexandru (Journal article; Peer reviewed, 2016)Current methods for ultrasonic pitch-catch well logging use two receivers to log the bonded material outside a single casing. For two casings separated by a fluid, we find by simulation that increasing the number of receivers ... -
Simulation and modeling of ultrasonic pitch-catch through-tubing logging
Viggen, Erlend Magnus; Johansen, Tonni Franke; Merciu, Ioan Alexandru (Journal article, 2016)Cased petroleum wells must be logged to determine the bonding and hydraulic isolation properties of the sealing material and to determine the structural integrity status. Although ultrasonic pitch-catch logging in single-casing ...
