Proposal The presence of a mild scaling regime in a field necessitates effective measures to be taken to prevent scale formation before production is adversely impacted. However, in many cases the scaling regimes are too mild to be investigated by conventional laboratory inhibitor test protocols under realistic timescales. In such cases, laboratory testing of inhibitor chemicals can often be achieved by conventional methods only by artificially increasing the severity of the scaling regime, and thus potentially underestimating the field performance of the inhibitor. A novel dynamic core blocking test procedure which allows laboratory evaluation of inhibitor performance in such mild scaling regimes within realistic timescales has been developed and applied to a field-specific case. In this paper, we report the further development of this test method. We describe a field example in which inhibitor performance and inhibitory mechanism have been examined using this method, allowing scale squeeze treatments to be recommended at lower percent sea water breakthrough of ~ 30 % rather than the originally planned level of ~ 50%.
