The 9-5/8 in. Drag Block Tubing Anchor (DBTA) is being function-tested on surface to confirm proper operation before running in hole.
The Drag Block Tubing Anchor is designed to:
Maintain tubing stability inside the casing.
Prevent unwanted tubing movement and rotation.
Help control tubing loads caused by thermal expansion and operational forces.
Protect completion equipment by minimizing excessive mechanical stress.
A proper surface function test verifies smooth drag block movement, confirms tool integrity, and reduces the risk of non-productive time (NPT) caused by downhole equipment failure.
