Event Announcement: Formation Damage Prevention & Treatment


05 to 08 March 2012
Dubai, United Arab Emirates

The purpose of this workshop/course is to gain adequate knowledge in formation damage. This workshop will take us through the types and mechanics of formation damage, their preventions and treatments.

The economics of a project development may be jeopardised 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 workshop will educate us 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 workshop has been designed to cover different well stimulation techniques to achieve the best reservoir-wellbore communications.

Our discussions will be extended to remedial solutions to water shut-off, gas shut-off and scale problems in the oil and gas industry.
