Abstract

An apparatus for estimating an ambient environment at which organic scale will form in a downhole fluid includes a stress chamber disposed in a borehole in a production zone at a location of maximum pressure and configured to receive a sample of the fluid from the production zone and to apply an ambient condition to the sample that causes the formation of organic scale. A sensor is configured to sense formation of organic scale within the chamber and an ambient environment sensor is configured to sense an ambient environment within the chamber at which the formation of organic scale occurs. The apparatus further includes a processor configured to receive measurement data from the organic scaling sensor and the ambient environment sensor and to identify the ambient environment at which the formation of organic scale occurs using the organic scaling sensor measurement data and ambient environment sensor measurement data.
