What are expandable tubulars? Expandable technology is a system for increasing the diameter of the casing, liner or sand screens of an oil well by up to 20% after they have been run down-hole. This expansion is done through a cold working of the steel by a larger expansion tool. This expansion reduces the telescoping effect that traditional casing plans have (large diameter at the top and small at the bottom). The advantage of this expansion is that a larger diameter well bore is possible at total well depth versus a standard casing string. This has benefits in deep drilling because wells can reach greater depths without a loss in final well bore diameter.
