Overview: From Underground Workhorses to Everyday Reuse
In the oil and gas world, pipes serve vital roles beneath the surface—and sometimes above it. Seemingly ordinary lengths of steel become the unsung heroes of drilling, well completion, and even farm fencing. These pipes often make a sudden market appearance once their primary duty is done, yet their afterlife proves just as fascinating.
Well Drilling and Tubing: High-Stress Life Underground
Occasionally, hundreds or thousands of new-appearing pipe lengths flood auctions and scrap yards. One tale surfaces from coal-seam gas sites: thousands of wells drilled, each with its own drill stem—often declared single-use due to safety and wear concerns. The cascading effect is a surplus of nearly-new drill pipe up for grabs.
A Fence in the Rough: Turning Oilfield Gear into Farm Tools
Ranchers and farmers have long known how to turn industrial leftovers into practical solutions. One account describes using 3.3-meter pipe segments as powerful fence posts—driven by skid steer machines, trimmed on top, and welded to rails. The practicality of repurposing these lengths saved time and money in rugged terrain, compared to hand‑dug holes in rocky soil.
Maintenance Matters: Wear, Grade, and Safety
Consider the story of a rancher who acquired surplus snubbing tubing after completion operations. Used supplier rail assemblies failed under livestock pressure; instead, the tubing provided sturdy, long-lasting posts. It was heavy to weld, and occasionally caused arc wandering in the weld puddle—but the posts endured while traditional materials failed. In conversation, someone quipped, “Worth a lot more as tubing than fence pipe,” reflecting their unexpected value.
Industry Standards: Certainty in Steel
International standards—like ISO 11960—define specifications for steel casing and tubing used in petroleum and natural gas wells. These standards ensure that pipes meet performance expectations and maintain safety across global operations.
From Field to Fence: The Lifecycle of a Pipe
In mid‑2025, a regional auction house in Queensland, Australia saw a steep drop in second‑hand drill pipe prices—from over AUD 300 per length during a cattle boom, down to AUD 80–90 before tax. This reflected both availability from winding coal‑gas drilling and shifting local demand.
In Summary: More Than Just Metal Tubes
These pipes bridge worlds—from high‑pressure wells to farm boundaries. They endure tremendous stress underground, undergo stringent inspection protocols, and, when retired, find new lives in fencing, construction, or ranch work. Their journey illustrates industry resilience, resourcefulness, and the unexpected afterlives of industrial materials.

Well Drilling and Tubing: High-Stress Life Underground
- Drill pipe: Heavy-duty, often seamless steel with tapered threads and tool joints at each end, this pipe transports drilling fluid and bit weight deep into the earth. It must endure immense stress, abrasion, and torque.
- Tubing (production or snubbing tubing): Lighter—around 6.5 lb/ft for a 2 7/8" string—it's pushed into wells during completion and production. In operations like snubbing, it plays a dynamic role: reaching into the well while managing high pressure both downward and upward at once.
- Drill pipe typically refers to the heavy-walled conduit used during the drilling phase.
- Tubing is lighter, used in production or completion phases, and in snubbing or workover scenarios.
- Tool joints are reinforced ends that connect pipe lengths and undergo wear through use.

The practicality of repurposing these lengths saved time and money in rugged terrain, compared to hand‑dug holes in rocky soil.
Maintenance Matters: Wear, Grade, and Safety
- Wear and inspection: Drill pipe is regularly monitored; tool joints and the inner and outer diameters wear down with use until they no longer meet safety tolerances.
- Hydrogen embrittlement: In high H₂S environments, even visually unblemished pipe can become brittle and fracture unpredictably—a costly failure during operations.
- Grade integrity: Steel grades such as S‑135 (135,000 psi tensile strength) and G‑105 (lower strength) are strictly controlled. Mixing grades risks failure and expensive “fishing” operations to retrieve broken tools from the hole.

From Field to Fence: The Lifecycle of a Pipe
- Phase 1: Exploration and Drilling
Drill pipe is rigged in, twisted, and pumped with fluid to mill through rock.
- Phase 2: Completion and Production
Tubing is run into the well—whether for production or high-pressure snubbing operations.
- Phase 3: Decommissioning & Surplus
Once worn or unsafe, pipe is removed and often auctioned as surplus.
- Phase 4: Rebirth on the Ranch or Farm
Fed into fence drivers or skidders, these pipes become posts, rail supports, or strainer arms—long-lived, cost-effective, and creative.
