The maximum velocity of bleeding solids phase flow when separated facilities are not overload.

Used in turbine drilling .Sonic vibration producer that setting up under the turbine reel producing vertical vibration and transmitting it to drill bit along the drill collar,making drill bit breaking up rock.

n: a specially designed nozzle that is installed in a line through which fluids are flowing. It is used to measure the volume of fluids. It works on the same principle as an orifice plate in that the nozzle causes a pressure drop from which volume of flow can be inferred. It is used where the velocity of flow is particularly high because the pressure loss through the nozzle is lower than through an orifice. See orifice plate.

n: a type of acoustic log that records the travel time of sounds through objects, cement, or formation rocks. Often used to determine whether voids exist in the cement behind the casing in a well bore.

a sonic log measures the interval travel time (delta t) of compression sound waves moving through one foot of a formation (milliseconds/ft). If matrix velocity is known, porosity can be calculated since sound waves travel slower in porous media (travel sl

n: see acoustic well logging. sonic meter n: see ultrasonic mete,;

n: A type of acoustic log that displays traveltime of P-waves versus depth. Sonic logs are typically recorded by pulling a tool on a wireline up the wellbore. The tool emits a sound wave that travels from the source to the formation and back to a receiver.

n: a vessel for absorption, adsorption, or desorption.

screened orifice valve.

n: a device used to extract oil and water from a core sample. A solvent vaporizes from a half-filled flask at the bottom of the extractor. Vapor rises to the top chamber and condenses there. The condensed vapor moves to the middle chamber until it is filled. Then the solvent is siphoned back through the sample to clean it.

a function where distance is the independent variable and another factor (magnetic, density, amplitude) is the dependent variable.
