Drilling fluids are often referred to as the "blood" of the drilling process, as they play a crucial role in determining both the efficiency and safety of drilling operations. Natural polymers, derived from renewable sources, such as cellulose, lignin, chitosan, xanthan gum, and starch, offer inherent advantages such as sustainability, biodegradability, and environmentally-friendliness when used as additives in drilling fluids. However, the inherent properties of natural polymers are adversely affected by thermal degradation due to their low heat resistance under harsh drilling conditions, where temperatures can exceed 150 °C.

- - The petroleum industry's growth has created a need for advanced oilfield working fluids, with liquid foam being a popular choice due to its benefits like low density and effective fluid diversion.
- - However, the limited lifespan of foam hinders its usage, leading to the exploration of cellulose nanomaterials (CNMs) which enhance foam stability and environmental friendliness.
- - This review discusses the types and preparation of CNMs, their use in stabilizing Pickering foams for oilfield applications, and outlines future challenges and opportunities for making the petroleum industry more eco-friendly.
The success of any drilling activity mainly depends on the characteristics of the drilling fluid. Therefore, a high-performance drilling fluid is substantial for any drilling operation. During overbalance drilling operations, the drilling mud invades the permeable formations and causes the loss of circulation, which is responsible for nonproductive time events.

- Cellulose derivatives like carboxymethyl cellulose (CMC) and cellulose nanomaterials (CNMs) are gaining popularity as eco-friendly additives in water-based drilling fluids (WBDFs) due to their biodegradable and biocompatible nature.
- CNMs, which include cellulose nanofibrils (CNFs) and cellulose nanocrystals (CNCs), offer unique properties such as a large surface area and enhanced mechanical performance, making them effective rheological modifiers and fluid loss reducers in drilling applications.
- The review discusses the structure, synthesis, and specific applications of these cellulose derivatives in WBDFs, while also addressing the challenges and future research directions for their effective use.
Drilling cuttings from the rock formation generated during the drilling process are generally smashed to fine particles through hydraulic cutting and grinding using a drilling tool, and then are mixed with the drilling fluid during circulation. However, some of these particles are too small and light to be effectively removed from the drilling fluid via solids-control equipment. These small and light solids are referred to as low gravity solids (LGSs).
