Abstract: A wellbore formation sample acquisition and analysis instrument includes an annular drill bit configured to couple to one end of a drill string. The bit defines a passageway extending from a cutting face thereof to an exterior surface at a longitudinally spaced apart position from the cutting face. The instrument includes at least one sensor configured to measure a selected parameter of a sample of subsurface formation urged into the passageway by action of the cutting face against subsurface formations. Samples of the subsurface formations are ejected from the exterior surface end of the passageway by the samples entering the cutting face end thereof.

Abstract: The invention concerns an optical fibre connector (15, 18) for high pressure (P) environments. Said connector comprises means for maintaining (1, 2, 19b) the respective ends of the fibres, facing one another. The invention is characterised in that it further comprises a sleeve (3) enclosing the fibre ends, and a translucent gel (4), provided in the sleeve to soak the space (4b) separating the fibre ends (15, 18). Moreover, by maintaining itself by capillary action in said space (4b) the gel seals off the connection with environment. The ambient pressure (P) then acts on one free end of the sleeve (3) while maintaining the gel (4) in the sleeve.

Abstract: A well for producing oil from an underground formation, comprises a vertical section extending from the surface to a depth below the oil-producing formation; a sidetrack or perforated interval (production zone) extending from the vertical section into the oil-producing formation; and a valve, located in the well, and operable to prevent flow of fluid from the vertical section into the production zone and a valve to prevent flow of fluid from the portion below the production zone into the production zone or into the vertical section above the production zone. A method of producing oil from the well comprises allowing oil and water to flow into the well via the production zone until the hydrostatic pressure of the oil and water in the well balances the formation pressure of the oil-producing formation such that further flow into the well ceases; allowing the oil and water in the vertical section of the well to separate under gravity so as to produce (i) a lower layer of water, at least part of which is located in the part of the vertical section below the oil-producing formation, and (ii) an upper layer of oil having its upper surface below the well surface and its lower surface above the production zone; forcing the separated oil and water back down the well and operating the valve such that substantially no fluid is forced into the production zone, an water is forced into the underground formation below the oil-producing formation; and allowing oil and water flow to recommence from the production zone.
