The enhanced Pipe Detector Tool (ePDT) is a two-inch O.D. advanced ferromagnetic metal thickness evaluation instrument. The integrity of multiple concentric tubulars strings can be evaluated in-situ. In most cases, this eliminates pulling the production tubing string, or disassembling the surface completion hardware to facilitate data acquisition. ePDT, is APC OFS’s Next Generation thickness instrument. It is based on evolutionary pulsed eddy current physics which permits quantitative thickness measurements for up to five concentric pipes.

The state-of-the-art instrument includes a new patented antenna that significantly improves measurement capabilities. This allows evaluation of tubulars ranging from 2-7/8-inch to 26-inch O.D.The ePDT is fully combinable with APC OFS’s Pegasus instruments, including Multi-Finger Imaging Calipers (MFC), Production Logging Tools (PLT) and our Digital Radial Bond Tool (RBL).

The combination yields a comprehensive evaluation of well integrity, providing accurate thickness information for multiple pipe strings as well as leak detection, multi-phase fluid flow and cement bond quality. During real-time logging via WarriorTM the software provides a comprehensive wellsite quality control display which offers clear visual indication of tool performance and pipe conditions. Post processing is performed with APC OFS’s proprietary module contained in the industry leading Well Integrity Evaluation Platform – MIPSProTM and PIPTM. When using PIP, all MFC, ePDT and ANT data can be processed, viewed, and interpreted side-by-side within a single software platform.
