Inorganic salts fouling is one of the operational problems
that pose major challenges to flow assurance of oil and gas
exploration and production. In order to act effectively in the
mitigation of this phenomenon, it is important to understand
its behavior under the conditions in which they occur, i.e, on
the "In Situ" pressures and temperatures. Photomicroscopy
technique can be an effective tool to achieve this goal as it
has the ability to provide measurement of the equivalent
diameter of a particle - even if it is under to high pressures and
temperatures.Asthisisnotawidespreadtechnique,ascurrent
laboratory methods are based on measurements under
ambient conditions, a photomicroscopy validation procedure
is proposed. The aim is to compare photomicrography to a
consolidated technology for determining particle or Drop
Size Distribution (PSD or DSD). The procedure consists of
the dispersion of solid calcium carbonate (CaCO3) in water
and simultaneous analysis by photomicroscopy and dynamic
light scattering. Comparison of the PSD diagrams of the two
techniques validates the procedure for ambient pressure and
temperature. The next step is to perform this procedure on a
pressurized and heated reactor.
