Using Solid Expandable Tubulars for Openhole Water Shutoff
In recent years, many operators in the oil and gas industry have moved to horizontal drilling, a process that has proven much easier than trying to move hydrocarbons into vertical wellbores. For the last several years, a major Middle East operator has been leveraging horizontal drilling technology to maximize oil recovery. Although hor izontal drilling technology has resulted in significant production increases, this operator saw that recovery efforts were somewhat hampered by water breakthrough in the horizontal openhole section of some wells. Unwanted water production is a problem for many operators, not just because of water content and reduced lift efficiency, but also because of the cost of water handling facilities and the cost of disposing of or re - injecting the unwanted water. This paper describes the planning and deployment of solid expandable tubular technology in the application mentioned above and cites an actual case history. This paper also discusses applications under development that leverage emerging solid expandable tubular technology.
