CDEx - Casing Design Expert

Casing strings are an indispensable asset to prevent the borehole from caving in, protect water sands from contamination, and control pressure in the well. They also serve as a path for production tubing, making it essential to determine a suitable casing string that can resist all potential loads while keeping budgets in mind. CDEx, PVI’s casing design software, implements an industry-accepted physics model to perform accurate and practical casing designs for complicated drilling circumstances. Burst, collapse, tension, compression, bending, buckling and temperature effects are all incorporated into CDEx to analyze the casing strings’ capabilities. CDEx analyzes the strength of the user-selected casing strings and automatically generates a reliable design solution using minimum expenses with three design options. This software allows the user to create multiple design scenarios in order to conduct comparisons. The intuitive user-interface makes the sophisticated casing design process easy and simple.FEATURES
