Tellus OCTG

Blade Technology Corporation, LLC Tools

Tellus OCTG is an app to determine the performance properties of oilfield tubulars (OCTG) as specified in the historical API 5C3 standard. It provides

  • API MIYP (Burst),
  • API Collapse with Tension adjustment, and
  • Pipe Body Yield Strength (PBYS),

of casing and tubing, and considers effect of temperature on yield strength.

The app includes an inventory of commonly used oilfield pipes, and custom sizes can be defined by the user.
