In an age of low cost oil with increasing lift costs, the challenge is to exploit and drain existing reservoirs as cost effectively as possible. Completion failures can be a major source of expenditure if not designed correctly, leading to unnecessary costly workovers or interventions in conjunction with deferred production. By using just a fraction of the existing available data in a structured and consistent manner allows selection of the optimum completion design. What must be included in a workflow to address this challenge?

The objective of this paper is to explain how a multi-discipline approach incorporating, geochemistry, production chemistry, production technology, and reservoir engineering can be applied and how the disciplines can interact with and complement each other. The resulting process is a robust structured workflow that can lead to significant improvements in sand control design and selection.

More time spent planning and designing lower completions as part of an integrated system can result in significant benefits to the operating company. The completion can be optimised resulting in an improved completion lifespan, lower CAPEX and OPEX costs and increased production volumes over the life of the field, while also taking into account environmental considerations.

This holistic approach has been incorporated into several field development plans and individual well completion designs on behalf of operators around the world.
