Used to detect surface and subsurface defects in ferromagnetic materials, MPI applies a magnetic field to the component while ferrous particles identify areas of flux leakage. It's one of the most reliable methods for locating cracks, pores, and weld defects before they become costly downhole failures.

How it works
DTI’s Approach to NDT
In an industry where undetected defects can mean the difference between a successful well and a costly failure, the quality of the inspection program matters. DTI’s Downhole Inspection Solutions team deploys five industry-recognized non-destructive testing (NDT) methods, each carefully selected and applied based on the specific demands of the component, application, and operating environment.
From surface defect detection to deep material analysis, here’s how we do it.

Inspection methods
ET induces electric currents or magnetic fields within a test object and measures the electromagnetic response to identify defects. Particularly effective for inspecting oil country tubular goods (OCTG) such as drill pipe and production tubing, it delivers fast, accurate results across high-volume inspections.
Using high-frequency sound waves, UT identifies internal flaws and material irregularities that aren't visible to the naked eye. Trusted across multiple industries for its precision, it's an essential tool for characterizing material integrity and detecting subsurface defects in critical downhole components.
LPI detects surface-breaking defects in non-porous materials including metals, plastics, and ceramics. Through a straightforward process of surface preparation, penetrant application, and excess removal, it provides a clear and reliable indication of any defects that could compromise equipment performance.
The most widely used NDT method across all industries, VT provides fast, effective quality control at every stage of fabrication or maintenance. In oil and gas, it's most applied to the threaded connections of OCTG and bottom hole components, a simple but essential first line of defense.
