Abstract
The design of technology for drilling directional and horizontal wells is an important stage in the development of oil and gas fields, especially in conditions of complex geological structure. This topic involves the study of methods and tools used to create wells with varying angles and directions. Effective design of such wells is necessary to increase hydrocarbon production, optimize production processes and reduce drilling costs. The scientific article discusses the main problems in the design of technology for drilling directional and horizontal wells, as well as ways to prevent them, including the selection of suitable formulations of drilling fluids. This article is intended to summarize the key aspects of the design of directional and horizontal well drilling technology, provide an understanding of the methods and tools used in this process, as well as identify the main advantages and challenges faced by drilling engineers when working in this field.
