Downhole Memory Instrumentation

Gudiehawk-Web Header-Option 1 RV3 B&W.png

Guidehawk memory instrumentation sub captures multiple data points downhole.

Analyzing downhole parameters are critical and necessary for reliable and efficient operations and learnings. Understanding the movements and forces directly connected to the bottomhole assembly, has helped improve the tool’s overall performance. Kobold developed the Guidehawk to ensure ongoing improvements in its downhole developments, along with capturing important post-frac data analysis for operators.

Guidehawk is a uniquely designed memory instrumentation sub that measures strain, pressure, temperature, shock and tool orientation. The Guidehawk solution allows for accurate downhole data to monitor tool movement between and during frac operations. This data sub provides assurances that the Sandhawk bottomhole assembly has opened or closed a Sandport sleeve.


Advancing our technology.

Kobold engineered Guidehawk to advance our downhole technologies, based on the data accumulated during thousands of well completions. This instrumentation has also been beneficial for coiled tubing, service providers and operators with post-job analysis, to better understand the downhole environment. Guidehawk has given us the ability to identify potential well integrity issues and help mitigate risks.

Kobold’s Research & Development team continue to optimize data capture solutions for real-time Guidehawk applications.
