Hydrate Control in Drilling Mud

This book provides pathways and strategies for mud engineers and drilling students in the future drilling industry. The data on the effect of drilling mud additives on hydrate formation thermodynamics and kinetics are discussed to aid proper additives selection and blending for optimum performance. Practical field operations of hydrate-related drilling are discussed with insights on future drilling operations.

Preface Drilling fluid design is very crucial in all drilling operations. Gas hydrate wells or hydrate sediments are future reservoirs that are believed to produced clean natural gas that will replace the current fossil fuels. Hydrate management has now become a part of the drilling operation and for that matter, relevant knowledge and guidelines of drilling  fluid design for hydrate management in drilling-related operations would help establish a strong foundation for hydrate-related drilling operations.

This book is useful to mud engineers, students, and industries who wish to be drilling fluid authorities in the21st-century energy production industry.

Dr. Bhajan Lal is a senior lecturer in Chemical Engineering Department at the Universiti Teknologi PETRONAS. He is a core research member of the Carbon Dioxide Research Centre in the Institute of Contaminant Management at UTP. After receiving his PhD degree, he worked as a postdoctoral research fellow and Research Scientist in the USA, Canada, South Africa, Turkey, and Malaysia. His main areas of research interests are clathrate hydrates, CO₂ capture and storage, natural gas storage, flow assurance (gas hydrate as well as corrosion), gas hydrate-based wastewater treatment, and water-based drilling fluid. He supervised master, Ph.D., and postdoc students since 2013. He has published 70 peer-reviewed journal papers, 38 conference papers, and 4 book chapters, and a book titled 'Chemical Additives for Gas Hydrates'. In addition, as project leader, he has secured 8 gas hydrate-related research projects worth RM 2 million from oil and gas industries, UTP, and the Malaysian Government.
