    Well Control - RILS

    This is a Remote Instructor Led Series training, all training sessions will be delivered online with no face-to-face classroom attendance.       

    Recommended to cover a maximum of 4 hrs per day.   

    This course will teach participants about the physical principles and concepts related to maintaining and regaining pressure control of wells while drilling.  Starting from concepts of formation pressure, fracture pressure, and factors which affect inflow, participants will gain an understanding of the elements of primary and secondary well control methods.  Well design concepts to improve pressure containment and reduce risk of secondary well control situations will be covered in detail.  By listening to the well, participants will learn how to identify potential well control situations in advance of their occurrence.  A brief overview of well control equipment, their operation, and testing will be covered to the extent necessary for the participants to identify requirements in the well planning phase.  Classical well control methods will be covered and several well control problems will be worked using several standard well control worksheets. This course will complement and prepare the participants for other courses which are part of a certification process.
