Efficiency and Low-Cost Benefits
Casing magnetization emerges as an efficient and cost-effective solution for contingency planning and relief well planning. Magnetizing the casing in advance proves to be a cost-efficient approach to amplify the detectable range when employing passive magnetic ranging (PMR) techniques. This method is particularly advantageous when dealing with challenging well conditions such as shallow wells, dense fields, salt formations, or when active magnetic ranging (AMR) is less suitable.
Enhanced Detection Range
After pre-magnetization, the detection range typically expands from less than 10 meters to 20 meters or more when ranging for a casing shoe. This range further increases when aiming for the middle of the casing. This expanded detectable range is instrumental in well-avoidance measures, shallow relief well intersects, and scenarios where PMR is the preferred ranging technique.
Documentation and Quality Assurance
Casing Magnetization Services (CMS) goes above and beyond by providing detailed documentation of magnetic field strength for each joint before and after magnetization. Every joint is properly marked, and the final report outlines the specific order in which the joints should be installed in the wellbore. This meticulous approach ensures the effectiveness of the magnetization process.
Casing magnetization stands as a testament to our industry’s commitment to safety. By adopting this method, drilling operations not only mitigate the risks associated with uncontrolled blowouts but also enjoy a streamlined and cost-effective approach to well control.
