ABSTRACT
The article discusses various drilling methods used in civil engineering, notably rotation and rotary-percussion, tailored to the nature of the terrain and drilling objectives. It details the components of the drilling string, such as standard rods and heavy rods, as well as drilling tools like tricone bits and roller bits, classified according to the IADC code. The article also covers the ODEX method for simultaneous drilling and casing in unstable terrains, as well as air reverse circulation for efficient sampling. Drilling parameters, the importance of drilling muds, and rotary coring techniques are also discussed, highlighting the evolution of coring methods and tools to optimize performance and reduce costs.

INTRODUCTION
Drilling is an essential step in many civil engineering and construction projects, providing access to the subsoil for various applications such as resource extraction, foundation installation or geotechnical studies. The selection of the appropriate drilling method, whether rotary or rotopercussion, depends on the nature of the terrain and the specific objectives of the project. This article explores in detail the different drilling techniques, the tools used, and recent innovations that optimize the efficiency and reliability of drilling operations.
