The integrated approach to sand management is crucial to address the sanding risk in the producers and injectors in the North Sea mature field. The concepts incorporates the LEAN approach and developed with major focus on the rehabilitation of mature fields where each barrel of oil counts and uncertainty, both technical and economical, are becoming more challenging at industry level. High decline in productivity and increased operational challenges are common issues for mature fields.

The sand management is divided into 4 major live phases which are sand prediction, sand prevention, sand production and evaluation/feedback. Each stage is mapped and associated with field redevelopment plan, project management control level, the time cycle (short: operation efficiency, medium: production optimization and long: reservoir management), digital oilfield, roles and responsibilities, enabling technologies and fine-tuned workflows.

History case including the utilization of dynamic multiphase flow simulator to fully understand the water hammer sanding behavior and the remedial job enabling technologies will be discussed briefly to demonstrate the utilization of the integrated sand management approach.

The paper will also highlight the key challenges to ensure that the sand management is a continuous improvement effort that is suitable for high level planning and yet practical for day to day operation.

The sand management has been developed based on multidisciplinary approach, lessons learnt and best practices acquired in mature field rehabilitation projects with major consideration to maximize the recoverable reserves and optimize the matured asset added value creation.
