.... Detailed analysis identified this application can benefit from running cutters with a non- planar cutting face on a field-proven seven- blade PDC bit frame. The bit was run on a Rotary Steerable System (RSS) coupled with a positive displacement motor (PDM) on top of the BHA to further improve the drilling...

... While the two bit runs delivered excellent performance, the bit showed more performance improvement by using high speed motor as the ROP increased by 39% versus the rotary BHA, this ensures the capability of the bit to work on all BHA and this thanks to the improved impregnated bit design using...

..., the drilling team evaluated drilling a 10 5/8 × 12 ¼-in. section reaching the top of reservoir—10 m true vertical depth (TVD) above the predicted top of the Mime formation—with minimum rathole. A standard underreaming bottomhole assembly (BHA) with one ball-drop reamer leaves a 35-m to 40-m rathole below the 9...

... further processed to deliver the well tool face and – with the help of a mathematical BHA model – the dogleg severity of the well. In one case the well tool face confirmed the orientation of the whipstock and the window milled. However, in a second case, the measurement revealed a 40 degree deviation...
