EMI Continuous Rod Inspections

Inspections of continuous sucker rods have traditionally been done visually in the field by experienced rig crews, but this method is imprecise and largely dependent on the operator's expertise and attention to detail. Often, defective rods will not be caught with a visual inspection, and can be run back in the hole, leading to premature failures. Conversely, if too much rod is scrapped, the operator might have a more expensive workover than necessary to replace the rod string.

Electromagnetic inspection will allow LPS to detect any imperfections or corrosion in the rod string that is not always detectable by a visual inspection. EMI inspections can detect cracks, pits, wear, stretching, and even defects underneath the surface of the rod. This process allows the operator to make an educated decision on the condition of the string, enabling swift decisions once the rod is pulled out of the well.

LPS' portable, proprietary, patent-pending EMI unit will detect imperfections on your continuous rod string while on location. If repairs are necessary, the rod in poor condition will be marked and removed before running the rod string back into the well.

All results will be inputted into a qualified report and kept in LPS' tracking program for LPS' and the customers' reference.

Unique Advantages

• Patent-pending EMI technology can avoid running rod in poor condition back into the well resulting in premature failures, unnecessary workover cost and lost production.
• Reduce downtime caused by repeated failures by identifying all defects upon inspection.
• Generates a detailed well profile to highlight problems within the wellbore.
• Identifies rod in acceptable condition which can be reused, often saving the operator from purchasing new material.
• Advice on types of defects allow engineers to make decisions to improve runtimes.
