Utilization of Biopolymers in Water Based Drilling Muds
With the increase in energy demand, deeper wells drilling is one of the solutions to fulfill the energy demand, which demands specialized drilling mud formulation. These muds are composed of thermally stable materials that can sustain in high-temperature conditions. Biopolymers are widely used out of various mud additives for improving the rheology and filtration characteristics of mud. Owing to the high temperature and poor thermal stability of such additives, these additives lose their primary functions, resulting in the nonproductive time and irreversible problems. The book chapter highlights the uses of water-based mud, its limitations, and the degradation of biopolymers. Various additives’ significance and susceptibility in harsh borehole conditions have been discussed. The existing additives used for the rheological and filtration characteristics improvements and their shortcomings are presented. Furthermore, the field applications of native and modified polymeric-based mud formulations have been further examined and presented.

Deep Eutectic Solvents as a New Frontier in Drilling Fluid Design: Opportunities and Challenges
The chapter covers the topic of deep eutectic solvents (DESs) and their potential as drilling fluid additives, focusing on their use as mud rheology modifiers, shale swelling inhibitors, and hydrate inhibitors during drilling. The properties and characteristics of DES, as well as their advantages and disadvantages, are discussed in detail. The environmental benefits of DES-based drilling fluids, compatibility with other drilling fluid additives, and potential future applications are also examined. Additionally, the challenges and limitations of using DESs as a drilling fluid additive and the safety concerns associated with their use are highlighted. Overall, this chapter provides a comprehensive overview of the use of DES in drilling fluids and its potential to improve the efficiency and safety of drilling operations.
