In addition to their size, jumbo drill bits are also known for their durability and longevity. Due to the harsh conditions in which they are typically used, these drill bits are constructed from high-quality materials that can withstand the wear and tear of heavy use. This ensures that they can continue to operate effectively even in the toughest of conditions.

The tapered drill string is characterized by its gradually reducing diameter from the top to the bottom. This reduction in size not only optimizes the weight distribution along the string but also enhances its flexibility, enabling it to navigate through challenging formations with ease. The smaller cross-section at the bottom end lessens the drag and torque, which is particularly beneficial in horizontal or directional drilling where friction can be a limiting factor.

The polymerization of resin monomers was initiated in the presence of nanofibers as structural templates to prepare a hydrogel with nanofibrous networks, followed by the drying and pyrolysis to get hard carbon aerogel. During polymerization, the monomers deposit on templates and weld the fiber-fiber joints, leaving a random network structure with massive robust joints. Moreover, physical properties (such as diameters of nanofiber, densities of aerogels, and mechanical properties) can be controlled by simply tuning templates and the amount of raw materials.
