Document Type and Number:
WIPO Patent Application WO2004094767
Kind Code:
B1
Abstract:
A borehole may be drilled utilizing the bottom hole assembly (10, 50) with a downhole motor (14), which may offset at a selected bend angle. A gauge section (34) is secured to the bit (16) has a uniform diameter bearing surface along an axial length of at least 60% of the bit diameter. The axial spacing between the bend and the bit face is controlled to less than fifteen times the bit diameter. After drilling a section of the well with the BHA according to the present invention a tubular may be inserted in the well by passing the tubular through an upper tubular, then the inserted tubular expanded while downhole to a diameter substantially equal to the expanded tubular.
