Solid Inhibitor
Baker Hughes introduced its ­SorbUltra
solid inhibitors, which can minimize
the risk of expensive interventions and
lost production in offshore wells. The
solid substrate on which the inhibitor
is applied is engineered to help ensure
reliable applications in deepwater envi-
ronments and can be customized to
treat a range of downhole conditions
including scale, paraffin, and asphal-
tene deposition. The treatment begins
in the propped zone as soon as produced
fluids contact the SorbUltra inhibitors
(Fig. 8). This process occurs before the
produced fluids reach the near-wellbore
region, where temperature or pres-
sure ­changes commonly cause flow-­
assurance problems. The treatments
have lasted longer than conventional
liquid-flow-­assurance chemistry, and,
depending on the well production, can
remain in production fluids at effective
levels long after they are pumped. The
inhibitors are applied as part of the well
stimulation to obstruct deposition in the
near-wellbore environment and forma-
tion. They can be run in new or existing
wells as part of a propped stimulation,
such as a gravel pack or fracture pack,
and are ideal for wells with closure rates
in excess of 8,000 psi. JPT
