The fluid journey from reservoir pore to process facility involves many disciplines. An integrated approach is necessary to maintain production and meet (or improve) recovery. Electrical submersible pumps (ESPs) and subsea flow boosting are effectively lowering the pressure at the sandface. Intelligent monitoring allows timely decisions that help to extend asset life. Multiphase flowmeters are increasingly used on every well, to optimize reservoir management and as a cost-effective allocation tool. Deepwater logistics and costs necessitate well designs that eliminate or at the least minimize the need for interventions.
Flow assurance is ‘keeping the flow path open.’ It is a complex life-of-well and reservoir process requiring understanding of subsurface conditions and fluid properties at all points along the journey. These drive the effective designs of for wells and facilities, and of operationsal procedures.
Monitoring pressure, temperature, and flow rate at various locations is key to managing production and increasing recovery. Fluid components and properties can change over time and must be understood to maintain production.
Lowering pressure at the sandface can significantly increase production and recovery. Today there are two options to consider: electrical submersible pumps (ESPs) and subsea multiphase boosting pumps. An approach that integrates reservoir, environment, and infrastructure considerations is necessary.
Production and injection affects the levels of subsurface stress during the life of an oil or gas field and can cause severe challenges, such as compaction and subsidence, changes in reservoir permeability, water breakthrough, fault reactivation and breaches in caprock integrity.
