Formation Damage
Evaluation & Control Strategies

Duration: 5 Days
Target Audience: Reservoir Engineers, Production Engineers, Drilling Engineers, Completion Engineers, Well Intervention Specialists
Delivery Mode: Classroom / Virtual with Diagnostic Exercises, Prevention Planning, and Case Studies
Level: Intermediate to Advanced

Course Overview

This course equips participants with the knowledge and tools to identify, evaluate, and mitigate formation damage in oil and gas reservoirs. It covers mechanisms of formation damage during drilling, completion, production, and stimulation, diagnostic techniques, laboratory evaluation, and best practices for minimizing damage to enhance well productivity.

Day-by-Day Outline

Day 1 – Fundamentals of Formation Damage

- Defining formation damage and its economic impact
- Natural and induced causes of formation damage
- Mechanisms: fines migration, clay swelling, emulsion blocks, scale, paraffin
- Recognizing damage symptoms from production data
- Exercise: Identify potential damage scenarios from field case studies

Day 2 – Drilling & Completion-Induced Damage

- Drilling fluids interaction with formation: filtrate invasion, solids plugging
- Mud additives, filtrate control, and impact on permeability
- Completion fluids selection and displacement techniques
- Mechanical damage from perforations, slotted liners, gravel packs
- Workshop: Develop a mud and completion fluid program to minimize damage

Day 3 – Diagnostic Techniques & Evaluation

- Well testing and pressure transient analysis for damage diagnosis
- Core analysis and laboratory methods
- Production logging tools and flow profiling
- Damage evaluation using skin factor and productivity index
- Exercise: Interpret well test results to estimate damage severity

Day 4 – Damage Control & Remediation Techniques

- Chemical treatments: acids, solvents, clay stabilizers
- Mechanical solutions: reperforation, hydraulic fracturing
- Water control and fines stabilization
- Strategies for controlling damage during stimulation
- Workshop: Design a remediation treatment for a damaged well

Day 5 – Best Practices, Case Studies & Prevention

- Planning for damage prevention in well design and operations
- Integrating drilling, completion, and production strategies
- Case studies of formation damage prevention and remediation
- Cost-benefit analysis of damage control strategies
- Capstone Project: Develop a formation damage control plan for a field development scenario
