Majosta Well Integrity: Cement evaluation, corrosion, leak detection, uneven depletion, perforation efficiency

Cased hole in general is a practical topic and expertise is based on field experience. The term "Well Integrity" is used in many capacities in different domains in the oil and gas industry. To the driller, Well Integrity means drilling the hole to plan. To the production engineer, Well Integrity means installing the tubular and the wellhead without problems and to the reservoir engineer, Well Integrity means the productivity index is not degraded by the positive skin. Well Integrity in this book covers the well operations and longevity once the casing is run in the hole. This covers the following: • Well Cementing. • Cement squeeze and remedial cement work. • Cement evaluation tools and their applications. • Corrosion Mechanisms. • Corrosion Monitoring tools and their applications. • Perforation's conveyance, Perforation hardware, and Perforation efficiency • Leak detection and the various tools used to detect and quantify leaks inside the casing and in the annulus behind the casing. • Uneven depletion and lnterzone cross flow in commingled production. • Water and gas conning. The book is focused on well-related problems after completion. This is the first time that all these topics are covered in one book. The book focuses on the practical side with over 100 field examples covering the topics mentioned above. Field-wide problems such as water flooding and changes in the oil-water and oil-gas contacts are outside this scope.
