PCT No. PCT/GB97/00200 Sec. 371 Date Feb. 1, 1999 Sec. 102(e) Date Feb. 1, 1999 PCT Filed Jan. 24, 1997 PCT Pub. No. WO97/27381 PCT Pub. Date Jul. 31, 1997When drilling a borehole for an oil well it is desirable to know when fluid is passing through the walls of the borehole between the borehole itself and the formation through which the borehole is passing. It has now been discovered that useful ...

In a hydrocarbon well, a speed measurement is performed at substantially the same level as a determination of the proportions of the phases of the fluid flowing along the well in at least one local region. To this end, local sensors (48) are placed on the hinged arms (22) of a centering device, and a speed-measuring spinner (20) is placed between the arms (22).
