Well Plan into Casing Design with

Drilling Engineer

Drilling Engineer
New Version of Drilling engineer

Tri-Axial Casing Design features both Bi-Axial and Tri-Axial calculations

Bi-Axial calculations are based on the working stress throughout the casing string. Tri-Axial calculations are based on the maximum Dog Leg Severity from Well Head to Casing Shoe, The user also has the option to select any measured point between two measured depths which will indicate the maximum DLS between the two depths

Casing Design now includes a new summary function you can add your casing section to the summary as you build your design.
