Abstract
Scale deposition in reservoir will cause the permeability reduction and flow assurance problem, which will cause negative impact on oil production. Squeeze treatment is a common practice in many deepwater projects to mitigate scale risks at the near wellbore area. Formation will be protected as long as concentration of inhibitor is above minimum inhibitor concentration (MIC), which is the most important factor in squeeze treatment. Static bottle test and dynamic tube-blocking test are two major methods to determine MIC as well as for scale inhibitor screening. They may not adequately represent the flow behavior of inhibitors in porous media. The coreflood test is under flow condition in porous media, which can simulate the reservoir condition. Therefore, the work focus on systematically investigating the performance of inhibitor in core and determining the MIC of inhibitor using coreflood method. The overall goal of this project is to improve the reliability of MIC testing and optimize scale squeeze design.
