Formation Damage: Causes, Prevention, and Remediation (PRE46)
1-5 September 2025 5 days NEW! Vienna, AustriaCourse Fee: 4350 EUR + VAT
Description
Formation damage in oil, gas, and water injection wells has a significant impact on techno-operational performance, HSE (Health, Safety, and Environment), and overall profitability. Damaged wells typically produce less, present additional challenges, carry higher risks, and demand more time, effort, interventions, and cost. Gaining a comprehensive understanding of formation damage involves exploring the reservoir matrix composition, identifying damage mechanisms related to drilling, well interventions, and produced/injected fluids, recognizing damage types, and selecting appropriate treatment methods.
This course focuses on the main types of formation damage, such as precipitates, clay swelling, emulsions, wax/asphaltenes, fines, scales, and oily or chemical residues, and how to prevent and treat them based on matrix type. It examines how damage occurs during drilling, cementing, perforating, production, and well interventions, and how to identify and remove it effectively.
Participants will explore acid stimulation techniques in carbonate and sandstone formations and their impact on vertical and horizontal well performance. The course also covers reservoir and rock type fundamentals, the principles of matrix acidizing, and practical well stimulation strategies aimed at restoring or increasing production or injection. Key topics include acid selection and formulation, job design and execution, and the critical role of coiled tubing in damage removal and matrix treatments.
