Installation Methods of Offshore Oil-Gas Well Conductor/Методы установки проводников морских нефтегазовых скважин

Издание на английском языке
The book is devoted to the study of offshore oil resources, which account for about 34% of the world's reserves. It describes the complexities and technologies associated with the construction and operation of offshore oil and gas wells that connect underground reserves to onshore facilities. The author examines three main methods of installing conductors: drilling, hammering and budgeting, emphasizing their unique requirements and complexities. The book is structured into five chapters covering the classification of conductors, construction technologies and their application in various geological and marine conditions. The author, who has more than twenty years of experience in the field of offshore petroleum engineering, shares the results of his research and practical work, hoping to contribute to the development of technologies in this field.
