Abstract:
This invention relates to a stabilizer ( 10 ) for a steerable drilling system, in particular for use in drilling directional boreholes for oil and gas extraction. There is provided a stabilizer ( 10 ) for a steerable drilling system having a first passageway ( 16 ) and a second passageway ( 18 ) at its outer surface, the passageways being helical and extending along the length of the stabilizer, the first and second passageways being oppositely-oriented, the first and second passageways intersecting one another, the stabilizer having a number of blades ( 22 ) between the passageways, the cross-sectional area of the first passageway being larger than the cross-sectional area of the second passageway. The asymmetric passageways enable the stabilizer designer to enhance the performance of the stabilizer during drilling and tripping.

Claim (Index 8):
The stabilizer according to  claim 7  in which the first and second helix angles have a same magnitude.
