Abstract
Drilling in the US Permian Basin shale play showed that interbedded formations can lead to deflection and High Local Doglegs (HLD). The effects are deviations from the well plan and a negative impact on the electronics within the steering unit. As a countermeasure, a combination of a pin-down connection steering unit with a short box-up bit was developed, allowing a shorter bit to steering pad distance. Integration of the Drill Bit in the Tool Design allowing a much shorter distance. Results show fewer HLD occurrences and improved steering accuracy. Novel solutions have been developed by further design and assembly method improvements. Utilization of Tapered and/or Polygon and other Geometries for the Taper proposed as novel solution. Assembly with Bit integrated Inductor. Competition in China and USL, other to be blocked in addition.
