TDAS

Tubular design and analysis system software

Stress and movement analysis

Ensure casing, tubing, and downhole equipment integrity during the service life of the well

Thermal analysis

Simulate multistring temperature profiles during well production or injection

Annular pressure buildup (APB)

Simulate pressure changes in downhole traps due to temperature changes during production or injection

Torque and drag analysis

Determine whether the tubular string can safely run in hole to the target depth

Minimize risks of pipe buckling, burst, or other failures

Since 1985, TDAS tubular design and analysis system software has been used to recommend secure operating envelopes for casing, tubing, and downhole equipment.

TDAS software simulates operational conditions to anticipate potential stresses and movements of casing, tubing, and downhole equipment. This information is compared with minimum design criteria and equipment operation envelopes to ensure tubular and equipment integrity over the life of the well.

TDAS software helps engineers predict and minimize risks, such as pipe buckling, under expected operating conditions.

The Triaxial plot compares the API and von Mises equivalent (VME) stress boundaries and the various operating conditions to highlight any potential risks.

The operational envelope shows a single packer with three operating conditions (isolated, plugged, and unplugged) and overlays these with various operating conditions over the life of the well.

Simplify analysis to save time without sacrificing accuracy

Compared to conventional software, TDAS software provides a user-friendly workflow and flexible, predefined load cases. The software supports a variety of completion equipment, handles complex string design, delivers an output summary with risk warnings, and embeds torque and drag analysis.

TDAS software follows industry standards such as API Specification 5CT, Specification 11D, TR 5C3, and Specification 19V, among others.
