| Abstract | Since 1991, when oil was started producing from basement rock of White Tiger field, the oil and gas industry in Vietnam has made the most important contribution to the development of Vietnam. At the moment some of the biggest oil fields started entering the declining phase. Consequently, improving oil recovery (IOR) becomes much needed in field development planning, and is one of the main concerns for engineers in any reservoir management project. Among IOR methods, horizontal wells have been widely applied in the world, and proved to be a promising technique. In Vietnam, the use of horizontal well has been considered for a long time. The first horizontal well was drilled in 1995 in the White Tiger field. Up to now, many horizontal or highly deviated wells have been drilled and put on production in several fields in Vietnam such as Aurora, Ruby and White Tiger field. In this study, the applicability of horizontal well in the South-East Dragon field, which is a small fractured basement reservoir in Southern offshore of Vietnam, was assessed. Overview of the SE Dragon reservoir characteristics as well as all the technical terms related to the horizontal well technique was provided. Based on analytical and numerical analyses, the performance of the horizontal well was analyzed in real reservoir conditions, and compared with that of the vertical well. Several case studies were conducted to investigate the affect of the main control factors such as horizontal well length, and direction on the well performance. The major works -that have been done in this study can be summarized such as: Systematic review of flow equation and solution for a horizontal well An analytical assessment of horizontal well efficiency A numerical assessment based on simulation study of horizontal well efficiency A preliminary economic assessment. |
