Protecting Pipe, Preserving Well Integrity
Oil Country Tubular Goods (OCTG) are valuable assets designed to perform under extreme conditions in drilling and completion operations. However, even the highest-grade pipe can be compromised long before it ever enters the wellbore if improperly stored, handled, or transported.
This module from Hearty Energy Services outlines the essential industry practices that protect your OCTG investment from the mill to the field.
Why Proper Storage of OCTG Matters
Without proper storage:
-
Corrosion from moisture exposure begins quickly
-
Thread Damage can occur from impact or poor stacking
-
Ovality (Warping) compromises connection integrity
-
Coating Degradation leaves pipe vulnerable in critical zones
Hearty Energy follows API RP 5C1 and field-tested protocols to mitigate these risks.
OCTG Storage Best Practices
Proper OCTG storage prevents costly failures and preserves the mechanical properties of your pipe:
1. Use Appropriate Dunnage:
Place dry, treated wood or synthetic dunnage evenly under the pipe. Avoid uneven stacking that creates stress points.
2. Stack Heights by Pipe Diameter:
Limit the number of tiers based on casing diameter and wall thickness to prevent bottom-layer deformation.
3. Protect Threaded Ends:
Keep thread protectors on at all times during storage. Replace damaged protectors immediately.
4. Cover Exposed Pipe:
Where possible, store under roofs or use UV-resistant tarps secured tightly to prevent water pooling.
5. Conduct Regular Yard Inspections:
Perform inspections at minimum every seven days. Look for signs of corrosion, shifting stacks, or coating breaches.
Safe Handling of OCTG Products
Improper handling causes invisible micro-fractures that jeopardize well safety.
Hearty Energy mandates the following procedures:
✅ DO:
-
Use certified nylon straps or pipe handling tools with protective coatings
-
Lift bundles from multiple points to distribute load
-
Utilize taglines to control pipe during lifts
❌ DO NOT:
-
Use chains directly on pipe surfaces
-
Drag pipe across abrasive surfaces
-
Drop pipe from height during loading or unloading
Proper training reduces the risk of costly damage during logistics operations.
Best Practices for OCTG Transportation
Transporting OCTG safely requires more than strapping down loads:
– Securement: Use soft-edge padded straps and certified blocking to prevent lateral movement.
– Load Configuration: Stack evenly using spacer boards or stanchions between layers.
– Documentation: Maintain traceability by matching heat numbers and specifications on shipping documents.
– Inspection: Inspect loads at pickup and delivery points. Note and document any transit-related damage immediately.
