Production tubing is used to draw oil and gas out of the ground.
The tubing came from a well known as Defiant Pembina 3-12-49-12w5. Defiant refers to the company that owns the well, Pembina refers to the region where the well was drilled and 3-12-49-12w5 refers to the Alberta Township System (ATS) for referencing legal land descriptions in the province.
This particular well is about 1500m deep.
The actual location of the well can be seen on the map in the links section of this page.
