Formation Damage: What Causes It, Why Should We Care, And How Do We Visualise & Quantify it?
By Justin Green, Formation Damage Consultant at Premier Corex
Most, if not all, of us are aware of “Formation Damage” as a concept that should be avoided, but how does it manifest in the reservoir? Can a better understanding of Formation Damage reduce risk and uncertainty in the field? This session will illustrate the subject with real-world examples and case studies, covering:
- Why should we be thinking about Formation Damage?
- When and where does it happen, and what are the main mechanisms that we see?
- How do we investigate, visualise, and quantify it, and can these learnings be used to improve field decision-making?
- Can the techniques be applied to new focus areas like carbon capture?
A case study from an upcoming SPE paper will be also be used to illustrate how an operator used targeted studies to identify issues and find solutions for current and future wells.
