A method of monitoring fluid production in a well, comprises measuring over time local parameters at a series of locations along the well, each local measurement being responsive to changes in the parameters in the region in which it is made; measuring fluid properties in the well over time downstream from the series of locations; and determining changes in the local measurements and in the measur...

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).

The invention relates to aqueous plastic dispersions containing latex particles which present anionic groups and are characterized in that at least some of the anionic groups comprise aminated sugar alcohols in protonated form as counterions. The invention also relates to methods for producing same and to their use.

A method for producing concrete or mortar based on an exclusively vegetal aggregate, a mineral binding agent, and mixing water is described. Instead of the vegetal aggregate being premineralized in a separate step of the operation, 4 to 14 kg of a non-hydratizable, finely ground mineralizator is added for each cubic meter of vegetable aggregate when the concrete or mortar is being mixed. Raw calci...
