The increased demand for and reliance on energy resources, including those resulting from the discovery and development of new hydrocarbon commercial reservoirs, necessitates the use of new technologies such as drilling process optimization by reducing non-productive time, costs, and risks. Casing while drilling entails removing the traditional drilling string and using the casing string to transmit mechanical energy to the bit as well as circulate drilling fluid into the well. Casing while drilling has proven to be an efficient method that is constantly improving over time. to reduce risks, particularly those associated with the presence of a conventional drill string in the borehole, borehole stability, or loss of circulation Despite a number of technical or perception barriers associated with the use of casing drilling, the significant benefits of this technology, such as reduced drilling time and problems associated with the drilling string, make it an increasingly viable alternative to conventional drilling. The application of this technology has demonstrated that it can reduce well execution time and, in some cases, lower costs in relation to drilling depth.
