Sand Flow

Locate and quantify sand production in the wellbore

Sand production is a serious issue. It affects productivity and the integrity of well completions and surface assets. Locating the source and quantity of sand production downhole is the critical first step to managing sand effectively.


Sand Flow does exactly that. It precisely locates sand entry to the wellbore and provides a qualitative sand count, clearly identifying problem zones, even in turbulent flow conditions.


Delivered by our True Flow system using the Chorus (acoustic) platform; Sand Flow provides the clarity and insight needed to manage sand production more effectively.


Sand Flow is commonly used to diagnose a known sand production issue, but it can also be used proactively to ensure downhole sand control measures are working optimally.



  • Locate sand entry in the wellbore
  • Unexpected increase in sand production
  • Unconsolidated formation that requires regular intervention
  • Sand screen failure
  • Surface equipment failure


  • Understand the true sources of sand production
  • Understand sand production dynamics
  • Better well and reservoir management decisions, precisely targeted
  • Improve well system performance and extend productive life of asset
  • Maintain asset integrity

Sandbar - a remedial sand control solution

Managing and curtailing sand production is essential to maintain asset integrity and extend the life of the asset.  TGT has joined forces with Tendeka, an independent global completions company, to create a unique remedial sand control solution - Sandbar.


Sandbar uses our Sand Flow product to "find" and locate the source and quantity of sand ingress and Tendeka’s game-changing Filtrex sand control system to "fix" or repair the issue. As a final verification, Sand Flow is used again to "confirm" the remediation has been successful. Click here to read the press release
