28.01.2015

PDC Side-tracking Bits are Successfully Tested in Western Siberia:
- 123,8 sFD613M (A410)
- 123,8 FD513M (A473)

The bits were tested at the following drilling modes:
- Downhole drilling motor, 140-220 rpm;
- WOB - 3-6 tonnes;
- Drilling mud: polymeric, with density  1,14 – 1.20 g/cm³, flow rate 7 – 8 l/sec;

Current performance of 123,8 sFD613M (A410) bit:
Total meterage – 4635 m
Total circulation time – 1226 h
Total drilling time – 1098 h
Average ROP – 4,2 m/h
The bit will be run in other wells.

Current performance of 123,8 FD513M (A473) bit:
Total meterage – 2948 m
Total circulation time – 979 h
Total drilling time – 664 h
Average ROP – 4,4 m/h
The bit will be run in other wells.

The bits fully meet the requirements of Customer’s engineering and technological service.
