Gyrodata’s brand new Micro-Guide service provides a highly accurate picture of existing micro doglegs, providing you all information needed to precisely determine ESP and rod guide placement, and allowing you to mitigate premature failures in artificial lift assemblies.
A major player in the North American market estimates ESP failures due to unidentified dogleg severity at 4% annually. With a tolerance between the rotor and stator inside the ESP of approximately three thousands of an inch, being able to place the electric motor in a straight section of the well bore is essential to prevent the motor from bending. Bending of the motor may cause the rotor to contact the stator causing an electrical short, leaving you with an expensive replacement procedure.
Unknown micro doglegs can also result in poor placement of rod guides, such as those used with pump jacks. This poor placement can result in high side loading, increased drag coefficients and accelerated tubing and/or rod wear. Other effects include increased horsepower demands, necessitating larger motors and higher energy consumption. Poor guide placement may also increase gearbox wear and rod buckling.
Currently, doglegs are calculated based on data sourced from surveys of long course lengths, unknown accuracy, or age. The software used to calculate these doglegs assumes a constant curvature between data points, but this is rarely the case. The questionable result of these calculations is then used to determine stress.
Gyrodata’s Micro-Guide service provides you with an accurate deviation log, identifying micro doglegs based on data points with an interval of less than a foot. This data is collected on the fly, and in real time. Being able to identify undetected micro doglegs on artificial lift assemblies allows you to mitigate issues such as:
- ESP failures
- Rod Guide failures
- Premature wear and tear
- Excessive power consumption
- Warranty waivers
- Uneven bearing load
- Seal failures
