Depth Monitoring / Depth Tracker

Why is Depth Monitoring Important?

When oilfield operators and crew members are on a drilling job, they don’t want to leave things to guesswork and chance. Exact measurements are needed to operate the expensive and potentially dangerous drilling equipment. Without that depth monitoring data, serious accidents can occur that harms people, property, and even the surrounding environment.

Thankfully, the Laversab Model 4210 stand-alone depth tracker eliminates the need for speculation and enables users to record depth data while drilling with confidence. Having the ability to track, monitor, and record drilling processes can help oilfield operators determine the long-term viability of drilling operations within a given area. This stand-alone depth tracker is certified for use in Zone 2 hazardous locations, which are defined as atmospheres in which a mixture of air and flammable substances Ie.g., gas, vapour or mist) will persist for a short period only and is not likely to occur in normal operations.

The Model 4210 is a fully integrated depth tracking solution that includes safety barriers that enable users to directly connect an encoder, hook load sensor, and manual slip-switch. This unit is pre-loaded with Laversab’s user-friendly Depth Tracker Software, useful to configure and calibrate the depth tracker module. In the absence of Electronic Drilling Recorder (EDR) or data logger software, Laversab’s depth tracker is able to log the depth tracking measurements for a particular oilfield operation throughout its duration.


How Can a Depth Tracker Help?

Laversab’s depth monitoring unit includes easy-to-use software for sensor calibration and data recording. Existing encoder and hook-load sensors/cables can be used; alternatively, new ones can be provided at the customer’s request. Relevant applications for this depth monitor range from simple depth collection to advanced data logging and reporting.

Depth data is formatted as wellsite information transfer specification level 0 (WITS0) and/or well-site information transfer standard markup language (WITSML). This data can be stored locally or used by any external applications. If no EDR is available, the stand-alone depth tracker can serve as the primary depth logger.

Aside from the benefits previously mentioned, other key features include:

  • Independence – on-site crew can confirm measurement depths without bringing in another service company
  • Easy operation – the depth monitor is easy to set-up, highly portable, and hazloc certified (Zone 1 and Zone 2)
  • Flexibility – along with its ability transfer data over WITS0 or WITSML, it includes the following bus options: Wireless, Ethernet, RS232, RS485

In addition, the unit is capable of the following depth tracking measurements:

  • Bit Depth
  • Hole Depth
  • Rate-of-Penetration (ROP)
  • Block Height
  • Hook Load
  • Weight-on-Bit (WOB)
  • Slips In/Out
  • Date
  • Time

Finally, the Laversab Depth Tracker Model 4210 comes with the following specs:

  • 9 lbs IP66 package with a 10.4” display
  • Compatible with all major incremental encoders built for hazardous locations
  • Encoder Power Supply input: 5-8VDC; max. 110mA max. Current
  • Encoder Signal output: 0-5VDC Line driver; A A and B B, or A and B
  • Compatible with standard 24VDC 4-20mA hook load sensors built for hazardous locations
  • Hook load, encoder and manual slip switch sensor channels are ‘Ex ib’ rated
  • WITS input and output channels (rated Ex ic): RS232 and RS422/485

  • Stand-alone Depth Tracker: Model 4210

    The Laversab Model 4210 is a stand-alone depth tracker, capable of recording depth data while drilling. The stand-alone depth tracker is certified for use in Zone 2 hazardous locations. It includes easy-to-use software for sensor calibration and data recording. Existing encoder and hook-load sensors/cables can be used, or new ones can be provided. Relevant applications range from simple depth collection to advanced data logging and reporting.

    Depth data is formatted as WITS0 and/or WITSML™. It can be stored locally or used by any external applications. If no EDR is available, the stand-alone Depth Tracker can be the primary depth logger.

  • Depth Tracker: Option for 28XX

    The Depth Tracker is a fully integrated electronics module that adds depth tracking capability to the Laversab 28xx Series rig-floor computers. The module includes all the necessary safety barriers that allow the user to place the encoder, hook load sensor and manual slip switch in ‘hazardous’ locations. A user-friendly Depth Tracker Software is included, which allows the user to configure and calibrate the depth tracker module. If an EDR or other data logger is not available, the Depth Tracker Software can also be used for logging all the depth tracker measurements for the entire job duration.
