The purpose of this 3-day Formation Damage Prevention and Treatments course is to provide attendees with adequate knowledge in formation damage. The course will take participants through the types and mechanics of formation damage, and their preventions and treatments. The economics of a project's development may be jeopardized by failure to obtain the production target. Economics relies on a limited number of highly productive wells.

Formation damage is an impairment of reservoir permeability around the well bore, leading to low or no well production or injection. There are two types of Formation Damage namely: Pore/pore throat size physical reduction and relative permeability reduction. Formation damage is often quantified by “Skin” factor. Skin is strictly a measure of an excess pressure in the producing formation as fluids flow into a well. This excess pressure drop can occur from one or several of a wide variety of causes such as drilling mud, cement and completion fluid filtrate invasion, solids invasion, perforating damage, fines migration, formation compaction, swelling clays, asphaltene/paraffin deposition, scale precipitation, emulsions, reservoir compaction, relative permeability effects, effects of stimulation treatments, etc. Therefore, it is evident that formation damage problems are caused by the nature of our activities during the cause of interactions with our wells. The critical factor from a well completion and intervention standpoint is to limit, where possible, the creation of damage (especially severe plugging in the near wellbore area). This means, to avoid plugging of the perforations in a cased hole completion and to avoid plugging of the formation face in an open-hole completion. 

This course will educate participants on how to avoid plugging and how to restore wells with plugging problems in the perforations or formation face. Beyond taking steps to eliminate severe permeability reduction in the near wellbore area, the next step is to obtain the best communication of the wellbore with the virgin formation. Therefore, fluids selection is critical as damage to the reservoir can result in impaired production and substantial loss of revenue to the Operator. It has resulted in increased reliance on formation damage testing to select the appropriate fluid and/or clean-up technique. 

This course has been designed to cover the laboratory techniques involved in formation damage testing and different well stimulation techniques to achieve the best reservoir-wellbore communications. Our discussions will be extended to new stimulation techniques such as multi-stage fracturing with swelling packers and stimulation sleeves.  Also, depending on the interest of the participants we may cover specials topics such as Water / Gas shut-off and scale problems in the oil and gas industry.

Prerequisite: Drilling, completion and production engineering and operation background at any level and no prior training in formation damage is needed

A complete set of course materials and lunch is included in the Formation Damage Prevention and Treatments course.
