The Stubby – PDC Drillable
Casing Landing –Surface, Intermediate, Production
After the success and early adoption of the Fill Drill, a demand for a PDC drillable version arose for surface and intermediate casing strings. The Stubby was developed to meet this demand. With internals made from industrial grade aluminum alloy and dense bronze, the stroke length was reduced to minimize the drill-out time and amount of drillable material in the tool. It is this adaptation which gave the Stubby its name.
Despite the change in material, the Stubby series of casing landing tools is very robust, andis still the strongest part of the casing string. An integral mandrel sleeve was added to act as a drilling guide, as well as to keep the tool complete once the internals have been removed. The components are designed to re-center the PDC bit at every connection, facilitating a smooth drill-out and eliminating the potential to damage the PDC bit. The 7” Stubby quickly became our strongest seller, and has over 200 runs to date. It boasts an impressive 99.2% success rates at landing casing at TD, pitted against coal seams, swelling shales, surface gravel, shifting sands, doglegs, ledges and washouts world-wide.
