Formation Mineralogy Impacts Scale Inhibitor Squeeze Designs (SPE-113261)

摘要

Description. Scale inhibitor squeeze designs are often developed using short-core flow tests for estimating treatment life and fluid/rock compatibility, bottle tests for reservoir fluid/squeeze treatment compatibility, and guidelines for sizing the mainstage and overflush. Laboratory tests provide a relatively high level of successful squeeze designs. Occasionally squeeze treatments cause unexpected loss of production and short squeeze life. This paper discusses how formation mineralogy can improve successful designs of squeeze treatments even before laboratory tests are conducted. Aradial model will be used to demonstrate key principles of optimizing treatments.
