Cementing Technology and Procedures


Book Description

Primary cementing is the process of placing cement in the annulus between the casing and the formations exposed to the wellbore. The major objective of primary cementing has always been to provide zonal isolation in the wellbore of oil, gas, and water wells to exclude fluids such as water or gas in one zone from oil in another zone. To achieve this objective, a hydraulic seal must be obtained between the casing and the cement. And between the cement and the formations, while at the same time preventing fluid channels in the cement sheath. This requirement makes primary cementing the most important operation performed on a well. Without complete zonal isolation in the wellbore. The well may never reach its full producing potential. Remedial work required to repair a faulty cementing job may do irreparable harm to the producing formation.

Well Cementing


Book Description

Cementing is arguably the most important operation performed on a well. Well cementing technology is an amalgam of many interdependent scientific and engineering disciplines which are essential to achieve the primary goal of well cementing - zonal isolation. This textbook is a comprehensive and up-to-date reference concerning the application of these disciplines to cementing a well.``Well Cementing'' is envisioned as an upper-level university book, as well as a reference for practicing engineers and scientists. The first section of the book illustrates how the quality of the hydraulic seal provided by the cement sheath can affect well performance. The second section concentrates on the design phase of a cementing treatment, and various aspects of cement job execution are covered in the third section. The fourth section addresses cement job evaluation. The text is supported by many tables and figures, an extensive bibliography and an index. There are also chapters devoted to subjects which are currently of particular interest to the industry, including the prevention of annular gas migration, foamed cements, and cementing horizontal wellbores. The chemistry associated with well cementing is presented in detail.Most of the contributors to this volume are employees of Dowell Schlumberger, one of the leading companies in this field.

Physics and Mechanics of Primary Well Cementing


Book Description

This book covers the major physical and mechanical processes that unfold during cementing and subsequent well service, and which can affect the well integrity. Focusing on the underlying physics, it concisely presents the central concepts of well cementing. The authors discuss the displacement of different fluids in the annulus, the mechanical stability of cement subject to varying downhole temperature, pressure and in-situ stresses, and the impact of defects on cement integrity under different mechanical and thermal loads over the course of the well’s lifetime. The book identifies knowledge gaps and unresolved issues, and proposes new directions for future research and development. The book is a valuable resource for practising engineers in the oil and gas industry, academic and industrial researchers involved in oil and gas engineering, and to graduate students within this same sector.
