DRILLING IN TENSION VS COMPRESSION
TECHNICAL BULLETIN

Description:

This bulletin from HydroLOGICA compares drilling in compression versus drilling in tension, explaining how pull-down and pull-back pressures affect drill string loading. It outlines the risks of excessive compression (buckling, crooked holes, equipment wear) and the benefits of managed tension (straighter holes, longer equipment life, lower costs), along with a practical four-step process for balancing these forces during drilling operations.
