This standard describes a test method to screen scale inhibitors for their ability to prevent precipitation of BaSO4
or SrSO4, or both, from oilfield brines. The test method does not fix such critical variables as test brine composition,
test temperature, and test duration. It is the responsibility of the user of this standard to determine the most
appropriate choices for these parameters. For example, Pritchard, et al.2 address static tests using North Sea brines.
This standard is intended only for ranking the performance of different scale inhibitors under laboratory
conditions. It is not intended to establish field treatment rates. CAUTION: Unique field conditions encountered may
alter the performance ranking of the scale inhibitors.
Factors such as reaction kinetics, fluid velocity, transient composition, temperature and pressure changes, scale
adherence, and solids dispersion can significantly affect scale deposition under field conditions. Consideration of
these parameters is outside the scope of this standard. However, field conditions, field brine composition, and other
variables noted above should be considered at some point in the scale inhibitor evaluation prior to final selection for
field use.
