摘要： The invention is concerned with measuring the amount of liquid entrained in a gas flow. In particular, a method of detecting the amount of liquid entrained in a gas flowing in a process pipe (10, 50) comprises the steps of: generating sound inside the pipe; providing a medium at least partially composed of the process stream for the sound to travel and/or resonate in; detecting sound in the pipe; determining the frequency and/or amplitude of at least selected pitches of the detected sound; and determining the amount of liquid entrained in the gas flowing in the process pipe based on the determined frequency and/or amplitude of the detected sound. Sound transmission through the process stream is affected by the amount of liquid, and this can be used to determine the amount of liquid. The sound may be generated within the pipe, or by one or more speakers (32).

摘要： The invention concerns a blow-out preventer for closing a wellbore. A valve body includes a fixed valve plate, with a first hole aligned with the wellbore. A movable valve plate is located within the valve body, and has a second hole, which is normally aligned with the first hole. The movable valve plate can be driven to move the second hole out of alignment with the second hole and thus close the valve plate. The movable valve plate can be driven to rotate to move the holes out of alignment, and may be formed as a circle or pan of a circle with gear teeth along a circumferential edge.

摘要： A mechanism for coupling together a first tubular and a second tubular is described. The first tubular has a first substantially frustoconical mating surface provided at an end. The first mating surface has formed thereon a plurality of circumferentially extending and axially spaced grooves. The second tubular has a second substantially frustoconical mating surface provided at an end, the second mating surface having formed thereon a plurality of circumferentially extending and axially spaced ridges. Respective ridges and grooves are configured to interlock with one another to sealingly couple the first and second tubulars together such that the interlocking is effected by elastic deformation of the mating surfaces as the surfaces are pushed axially together. The plurality of grooves and ridges have an aperiodic spacing along a main axis of the tubulars so that wherein a spacing of at least one corresponding interlocking groove and ridge is such that a width of the groove is different to a width of the corresponding ridge.

摘要： A proppant particle for use in a hydrocarbon production operation is disclosed. The proppant particle has porous structure, the porous structure being formed of any of a plurality of carbon nanofibres or tubes synthesized on the surface of a core, and an alumina spinel based porous particle. The use of either of these types of material for a porous structure gives a lightweight proppant particle with adequate strength. This means that less water and/or chemicals are required to disperse the proppant particles during an operation such as fracking.
