Advanced well control

OBJECTIVES

To learn detailed well control procedures including volumetric and stripping methods and bull heading.

Learn to produce annular pressure profiles and deal with equipment failure. Other topics include: horizontal well control, correcting kick graphs, HPHT wells considerations, well control during casing and cementing and well barriers. Delegates are strongly advised to bring a laptop loaded with Excel in order to solve the many exercises given in this intensive course.

WHO SHOULD ATTEND?

Drilling Engineers, Drilling Supervisors, Rig Managers and Tool pushers. Some wellsite or operations experience and a basic knowledge of well control equipment are beneficial for this course.
