Case Study: Operator Identifies Shallow Surface-Casing Corrosion Without Costly Workover

Halliburton Electromagnetic Pipe Xaminer® V (EPXTMV) tool detects metal loss near wellhead

Challenge – Since the operator’s leak was impacting production, and similar wells in the area experience shallow surface-casing corrosion problems, the operator wished to know the extent of this potential problem to develop a remediation plan.

Solution – Halliburton recommended assessing the corrosion using the new Electromagnetic Pipe Xaminer® V (EPX V) tool. The EPX V tool uses High-Definiton Frequency (HDF) technology, which is capable of logging the well in a single pass, without needing additional services to assign metal loss per pipe string. Additionally, the 111⁄16-in. OD allows for assessing the 95⁄8-in. surface casing from within the 27⁄8-in. tubing.

The EPX V tool operates off mono-conductor wireline or in memory mode, which allowed the operator flexibility in choosing how to run it most efficiently.
