Your casing profile is the conduit that connects your downhole investment to the surface. An improper design can lead to costly repairs, loss of hole, or HSE incidents. Signa’s casing designs provide cost-effective solutions with high safety and integrity. Our registered professional engineers model your well using StressCheck™ software, with attention to burst, collapse, axial, triaxial, H2S, CO2, buckling, thermal effects, casing wear, and existing tubular issues. We ensure your well has the optimal number and length of casing strings, including expandable liners. All designs are consistent with API Bulletin 5C3, ISO/TR 10400 and ISO13679 (now required by BOEMRE). We engineer conventional casing designs or specialty designs like high temperature/high pressure (HTHP) and extended reach drilling (ERD) programs.
