Horizontal Wells: Applications, Considerations, and Case Histories

This paper discusses many aspects of the application horizontal wells for field development, starting with basic question why to opt this technology. The different considerations be taken into account when dealing technology are reviewed, including some inherent downsides like higher cost and operational complications. main emphasis, however, is placed on practical reservoir engineering aspects, well planning performance, handling in specific technical applications test
