The course will address the recommended practices of well integrity according to the international

standards and policies of reputable E&P companies. Discussion is carried out on how to

evaluate the Sustained Annulus Pressure (SAP), its origin, and impact on safety and well life

cycle. This course will go over the elements and operation of wellhead systems, which will

include the Christmas tree, wellhead, surface safety system.
