Enhancing the efficiency of interpretation and processing of casing inspection data by Circumferential Acoustic Scanning Tool - Visualisation and Multifinger Imaging Tool
Abstract
During oil and gas production (or water injection), the casing and tubing columns of wells are often deformed, corroded or damaged. Well logging methods have been applied for the inspection of technical conditions of casing and tubing columns in order to detect damages or predict the mechanical and chemical conditions of the tubes, thus preventing serious incidents and enabling timely repair to reduce economic losses and negative impacts on the environment. The development of a good method for interpretation and processing of casing inspection data is very important in order to improve the efficiency of interpretation and processing to produce quick and accurate results with visual images of the research objects.
The method developed has been applied to process the casing inspection data by Circumferential Acoustic Scanning Tool - Visualisation (CAST-V) and Multifi nger Imaging Tool (MIT) provided by Halliburton and Sondex. By enhancing presentation functions and supplementing new algorithms, the processing and interpretation of casing inspection data have been improved, satisfying customers’ requirements.
