Dealing with Dead Shorts in the Field

The only leak type that can be effectively dealt with in the field is a dead short. To determine if you have a dead short, you will need a good quality ohmmeter (Fluke) that reads to a minimum of 0.1 Ohms. Using this methodology  you can test to see if you have a dead short...


How to Identify Electrical Leaks in the Field

Although locating electrical leaks can be complicated, the majority of problems can be resolved in the field by a skilled operator using a good quality ohmmeter that reads to 1/10 Ohm. This can save a trip to the service center and allow the wireline unit and crew to finish the job.

Understanding Issues with New Cable

Wireline Cables are most susceptible to damage during their first few runs into and out of a wellbore, when the cable is essentially “new”. Although this seems contrary to what you would expect, the exposure to the wellbore environment helps “season” a new cable and prepares it for life into and out of a wellbore. These first several runs are critical to ensuring that you get the maximum life and least hassel from your cable...


7 Keys to Help Prevent Drum Crush

When logging the first "very" deep wells in West Texas, there were several electrical failures in US Steel cables that were labeled factory defects. It was discovered that all of the failures had occurred at a point in the cable that had not been off the drum, and in fact the shorts were several layers down from any point on the cable that had been in the hole. This was the birth of what is now called "drum crush"...


Single Break vs. Double Break

Years ago, the standard system for spooling a cable on a drum was the single break system. With this method the cable made the first wrap tight against the flange. As this first wrap is completed, the cable had to make a severe bend to step over a full cable diameter for the next wrap. This single break pattern was...
