Theories and Technologies of Bionic Drilling Fluids covers the development and use of bionics in drilling fluids. The book considers technical challenges and upgrades to existing drilling fluid technology, presenting a case for the use of bionics in the petroleum industry alongside environmental protection. In response to the increasing need for novel technologies, the title includes insights on how nature-inspired technologies can be successfully developed to help researchers and technicians harness the power of bionics to solve practical challenges. This volume presents over a decade's worth of original research on bionic drilling fluids, offering scientists and engineers a comprehensive handbook. Drilling fluid has contributed to the safe, efficient and smooth implementation of drilling engineering for over a century. However, in recent years, oil and gas reserves have been discovered in difficult-to-access, extreme environments such as the deep ocean. Consequently, geological and ground conditions have become increasingly complex, posing a challenge to resource exploration and development. Bionics, the imitation of characteristics, structures, functions and principles from nature, offers a new approach to drilling fluid technology. Highlights the environmental aspects of bionics in drilling fluids Offers a concise and clear guide to new theories and technologies in bionic drilling fluids Combines over a decade of original research with practical experience in petroleum extraction and development Provides efficient and low-cost technical means for solving drilling fluid-related technical problems Presents techniques already used by over 35 oil and gas fields, and in 12 countries around the world
