An operator in Eastern Romania was drilling in a formation predominantly composed of medium compacted claystone, sandstone intercalations, and poorly consolidated quartz sand.

The operator wanted to increase drilling performance and minimize the number of runs in a 12-¼in. section of its well while producing an excellent borehole.

Baker Hughes, a GE company (BHGE), proposed its latest hybrid bit technology to achieve the operator’s goals and finish the section in one run. The Kymera FSR™ directional hybrid drill bit design provides better tool face control, improves efficiency, and improves borehole quality.
