Main Objective

This project is expected to achieve the following objectives:

Provide an in-depth understanding of the capability and limitations of through-tubing casing corrosion logging technology and vendor tools;
Assist commercial through-tubing logging vendors to improve their technology though a collaborative experimental research that includes an iterative fit-for-purpose lab test program;
Develop a reliability-based assessment framework to inform decision making as it pertains to the deployment of through-tubing casing logs in casing corrosion management; and
Perform a field trial to demonstrate 1) the performance of selected through-tubing casing logging tools and 2) the newly developed methodology to implement the through-tubing logs in casing corrosion management.

Public Abstract

Project Description: This project will advance the current state of through-tubing casing inspection technology for underground storage wells. A fit-for-purpose lab test program including multiple rounds of full-scale physical tests will assist logging tool vendors to improve their commercial through-tubing logging tools. Specially designed artificial metal loss features installed in representative casing configurations in a lab test well will be used to quantitatively assess the tool performance to provide directional guidance for tool improvement. A reliability-based assessment methodology will be developed to inform the use and interpretation of through-tubing logs for casing corrosion management. A field trial will be conducted to validate vendor tool performance and demonstrate the new assessment methodology.

Anticipated Results: The expected outcome of this project is to establish a workflow that provides operators with improved efficiency in casing corrosion management using through-tubing inspection technology with reduced cost and well entry risk, defendable to regulators.

Potential impact on safety: A more accurate and reliable casing inspection data, improved decision-making for corrosion management with potentially reduced costs and risks, and a defendable approach for regulatory compliance.
