Bottom-Hole Assembly (BHA) at Petros Tubular Services

Your bottom-hole assembly takes the hardest service in the string, and a failure downhole is expensive. Petros performs specialized inspection of BHA and downhole components, checking the connections, bodies, and critical areas that see the most stress so your drill collars, subs, stabilizers, and tools stay reliable in the hole.

What we check

  • Drill collars, subs, stabilizers, and downhole tools
  • Connection and thread inspection, including box and pin critical areas
  • Body and bore inspection for cracks, wear, and damage
  • Dimensional checks against specification
  • Magnetic particle inspection of connections where required
