A method for the estimation of pore pressure within a subterranean formation containing fluid during the drilling of a bore hole 6. The bore hole is drilled using a drill string 4 consisting of a drill bit 5 fitted to its lower end, and using drilling mud pumped from the surface through the drill string and finally evacuated. The method is characterised by, whilst the drill bit is level with the f...

To discriminate optically between the various phases in a three-phase fluid, a light beam (F) of non-zero divergence is injected into a detector block (10) made of a material whose refractive index is greater than the refractive indices of all three phases of the fluid. The block (10) has a sensitive zone (18) and a total reflection zone (20) such that incident rays (Ri) parallel to the axis (12) ...
