Abstract
A system including a casing hanger; a wellhead housing, including a landing shoulder configured to contact the casing hanger during installation of the casing hanger in a wellhead; a transducer disposed on an exterior of the wellhead housing, wherein the transducer is configured to emit an input pulse toward the landing shoulder; and an ultrasonic transmitter coupled to the transducer, wherein the ultrasonic transmitter is configured to detect the input pulse and one or more echo pulses associated with the input pulse.

A system, comprising:
- a casing hanger;
- a wellhead housing, comprising:
- a landing shoulder configured to contact the casing hanger during installation of the casing hanger in a wellhead;
- a transducer disposed on an exterior of the wellhead housing, the transducer being configured to emit an input pulse toward the landing shoulder;
- an ultrasonic transmitter coupled to the transducer, the ultrasonic transmitter being configured to detect the input pulse and one or more echo pulses associated with the input pulse;
- and
- one or more sensors configured to receive the one or more echo pulses as the one or more echo pulses reverberate back in a direction from which the input pulse originated, the ultrasonic transmitter transmitting a signal indicative of the one or more echo pulses detected by the one or more sensors to a machine-learning model to perform binary classification to determine whether the casing hanger is fully landed, the machine-learning model being trained using data collected through a finite element method-based simulation model, the finite element method-based simulation model being configured to simulate ultrasonic test processes and utilize a simplified 2D axisymmetric model of a cylindrical structure to reduce computational time;
- and
- a controller configured to:
- control the transducer to emit the input pulse;
- monitor sensor feedback from the one or more sensors;
- control the ultrasonic transmitter to transmit the signal to the machine-learning model;
- and
- analyze the sensor feedback from the one or more sensors using a binary classification neural network.
A method, comprising:

- emitting input ultrasonic pulses from a transducer of the wellhead housing, the ultrasonic pulses reflecting off one or more internal surfaces of the wellhead housing;
- detecting the reflected ultrasonic pulses via an ultrasonic transmitter of the wellhead housing;
- receiving, via one or more sensors, the reflected ultrasonic pulses as the reflected ultrasonic pulses reverberate back in a direction from which the input ultrasonic pulses originated, the ultrasonic transmitter transmitting a signal indicative of the reflected ultrasonic pulses detected by the one or more sensors to a machine-learning model to perform binary classification to determine whether the casing hanger is fully landed, the machine-learning model being trained using data collected through a finite element method-based simulation model, the finite element method-based simulation model being configured to simulate ultrasonic test processes and utilize a simplified 2D axisymmetric model of a cylindrical structure to reduce computational time;
- recording the reflected ultrasonic pulses;
- and
- determining whether the hanger has landed on the landing shoulder by analyzing the reflected ultrasonic pulses using a binary classification neural network.
A system for wellhead installation, the system comprising:

- detect the input pulse and one or more echo pulses associated with the input pulse;
- reflect the input ultrasonic pulses off internal components of the wellhead housing;
- detect the reflected ultrasonic pulses via the ultrasonic transmitter of the wellhead housing;
- record the reflected ultrasonic pulses;
- and
- determine whether the hanger has landed on the landing shoulder by analyzing the reflected ultrasonic pulses using a binary classification neural network,
- wherein the one or more echo pulses are received via one or more sensors as the one or more echo pulses reverberate back in a direction from which the input pulse originated, the ultrasonic transmitter transmitting a signal indicative of the one or more echo pulses detected by the one or more sensors to a machine-learning model to perform binary classification to determine whether the casing hanger is fully landed, the machine-learning model being trained using data collected through a finite element method-based simulation model, the finite element method-based simulation model being configured to simulate ultrasonic test processes and utilize a simplified 2D axisymmetric model of a cylindrical structure to reduce computational time, and
