Coil Tubing Drilling
Coil tubing drilling (CTD) has found a niche when combined with underbalanced techniques, especially in Middle Eastern countries and Alaska, to unlock reserves in mature oilfields. Drilling times can be greatly reduced compared to conventional jointed-pipe drilling rigs. However, the method requires a great deal of planning and experience to execute properly and safely. Because the technique requires a built-for-purpose rig, it is imperative to understand all parameters, including directional departure, bits, BHAs, and fluid circulation. Signa has engineered CTD and overseen execution internationally by entering extremely low-pressured reservoirs, lengthening the wellbore, and increasing production. If you’re considering CTD, our engineers can walk you through the benefits it might hold for your reserves. We also engineer custom coil tubing drilling programs, including rig requirements, pressure profiles, directional plans, fluid programs, scheduling, vendors, and surface equipment layout.
