This course will focus on two critical components of well integrity – CASING DESIGN and CEMENTING. Key aspects of casing design will be discussed so that the Course attendees gain a good understanding on why a good casing design is critical in ensuring that the well retains its structural integrity throughout its life cycle.
The importance of obtaining a good primary cement job will also be covered including good cementing practices and evaluation including current cement bond logging techniques – ultra sonic imaging tool (USIT), circumferential acoustic scanning tool (CAST) and segmented bond tool (SBT) in addition to the conventional CBL/VDL techniques.
Well integrity considerations for hydraulically fractured wells will also be covered in the course. NOTE: It is not a primary objective of this Course to have the attendees become experts in Casing Design and Cementing, and in interpretation of cement bond logging techniques, but rather enable them to have a strong and clear understanding of these two critical well integrity components.
