Course Objectives:

This course covers all aspects of formation damage. It also realizes this damage and put the remedy to it.

Course Outline:

• Risks and causes  of formation Damage

• Invasion of drilling mud solids into the formation
• Drilling Mud filtrate invasion into the formation 
• Cement loses into fractures
• Plugged inadequate perforation
• Creation of emulsion in the formation
•  Injection of acids / solvents that contain solids
• Sand fill in the well bore
•  Excessive draw downs

• Risks and Causes  of Drilling Damage

• The case of vulgar or fractured carbonates
• The case of sandstone reservoir
• The case of open – hole uncemented liner completions
• The case of gravel – packed completion
• Procedures of minimizing drilling damage

• Perforation Damage

•  Solids plugging
•  Inadequate Clean up
• Overbalanced perforating

• Risks and causes of Fluid Damage

• Sluges or emulsions ( especially  From acid )
• Insoluble residues
•  API procedure for testing surface active agents
• Live and spent acid tests

• Risks and courses of sand fills

•   Necessary checks for sand fill ( e.g. wire line runs,  pump changes, workovers )
• Precautionary steps to be considered

• Planning for Blowout control operation

• Task force
• Materials
• Communication
•  Listing available products including ( cement, products, pumping facility, proximity tools, directional equipment, estimated quantities for various blowouts )

• Recommended practices for immediate well kills
• Geological / Depositional Environments Review
• How do Homogeneous or hetrogeneous are these reservoir formations and what is the influence of formation damage
• Reservoir properties review and what properties most influence the effect of formation damaged
• Damage Mechanisms ( how S.S and carbonate damaged )
• How do formation mineralogy and clay chemistry influence damage? what about scale paraffin , asphaltenes ?
• Damage perversion
• Drilling , Completion and production methods
• Drilling / Completion and production methods
• Drilling completion fluid additive selection and clay control
• Evolution of damage
• Damage Removal
• Acid zing materials and methods , non- acid approach such as (wellbore waskes perforating techniques and hydraulic fracturing)
• Reservoir Damage

•  Production Performance, pressure analysis review
•   Damage removal
•  Acid zing materials and methods, non- acid approach such as wellbore waskes perforating techniques and hydraulic fracturing to bypass damage
