Single-phase acid system simplifies design and delivery
To optimize the stimulation design and delivery program for the well,
the Schlumberger engineers compared options using the WellBook software
application for treatment design, execution, and evaluation, and Kinetix Matrix
matrix stimulation design. Simulations led the engineers to recommend an
OpenPath Reach extended-contact stimulation service with single-phase retarded
acid system delivered through coiled tubing.
Compared with HCl, the single-phase retarded acid system is much more
efficient at high temperature, delivering stimulation performance similar to
that of conventional retarded acid systems, such as emulsified acid. In
addition, compared with other retarded acid systems, the single-phase fluid
simplifies mixing and pumping operations, limits the equipment footprint
requirements, and minimizes the risk of emulsions during production.
