Detail

Course Description

Predict the rate at which a well should be capable of producing, given reservoir and fluid properties, wellbore configuration, and flowing wellhead pressure. Identify which components of the reservoir/completion/wellbore system are restricting performances; analyze production data to find permeability, skin factor, and drainage area; forecast future performance from historical production trends and from known reservoir properties.

Course Duration : 5 days
