Geological, geochemical, and engineering studies during the drilling process (mudlogging or gas logging) were introduced as a commercial service in 1939. This service provides continuous monitoring of drilling parameters, as well as the rapid identification and evaluation of rock cuttings during drilling, with the aim of correlating them and determining hydrocarbon production potential. High-quality methods for obtaining this data and its subsequent evaluation are extremely important factors in exploration and production drilling. The drilling of horizontal well sections is becoming increasingly necessary and effective. A horizontal well section is drilled to a specific depth in the target formation, which increases the contact area with the oil and gas reservoir. The primary objective of a horizontal well is to increase oil and gas production or improve the oil and gas recovery factor. With the development of horizontal shale gas wells, advancements in drilling technologies, and the demand for more accurate reservoir analysis, as well as the need to improve quality, efficiency, and reduce costs, the integration of horizontal drilling models is becoming widespread. Gas logging, rock element composition, and geonavigation are integral components of drilling research and are grounded in oil and gas geology. The development of each aspect is outlined, and the relationships between them in practical application are analyzed to contribute to the exploration and development of oil and gas fields.
