This open access book offers a timely guide to challenges and current practices to permanently plug and abandon hydrocarbon wells. With a focus on offshore North Sea, it analyzes the process of plug and abandonment of hydrocarbon wells through the establishment of permanent well barriers. It provides the reader with extensive knowledge on the type of barriers, their functioning and verification. It then discusses plug and abandonment methodologies, analyzing different types of permanent plugging materials. Last, it describes some tests for verifying the integrity and functionality of installed permanent barriers. The book offers a comprehensive reference guide to well plugging and abandonment (P&A) and well integrity testing. The book also presents new technologies that have been proposed to be used in plugging and abandoning of wells, which might be game-changing technologies, but they are still in laboratory or testing level. Given its scope, it addresses students and researchers in both academia and industry. It also provides information for engineers who work in petroleum industry and should be familiarized with P&A of hydrocarbon wells to reduce the time of P&A by considering it during well planning and construction.

"Hole cleaning efficiency is an important factor of consideration in the successful evaluation of any drilling operation. This is dependent on the ability of the drilling fluid to effectively remove cuttings from the bottom hole to the surface, which are affected by changes in the drilling fluid properties such as the density, pipe eccentricity, well bore geometry, well bore interactions with the external environment in the form of gas-cutting etc. This work examines the sources and effects of entrained gas on drilling fluid, borehole and hydraulic parameters and their respective impact on hole cleaning. A generalized mathematical equation was derived to predict the hole cleaning efficiency of low-viscosity non-dispersed mud systems at different rates of gas entrainment. Additionally, the total pump operating cost was investigated from the knowledge of the optimum horsepower output of the pump. A cost comparison was made between the Hydraulic Horsepower and Jet Impact Force methods of optimized drilling. From the analysis it was observed that entrained gas negatively impacts hole cleaning in comparison to a gas free system. Jet Impact Force was found to be a better tool for determining the pump operating cost and estimating the hole cleaning performance using the Carrying Capacity Index"--Leaf iii.
