Monodiameter Drilling Liner - From Concept to Reality

The monodiameter well is a breakthrough in the oil and gas industry. Expandable-tubular technology allows multiple strings of the same size drilling liner to be installed in a well without a decrease in inside diameter (ID). The construction process involves installing a monodiameter drilling liner below the casing and expanding it and the overlap. The resulting ID allows additional monodiameter drilling liners to be installed and expanded without reducing the ID as in a standard telescoping casing program. Monodiameter wells reduce total drilling costs and enable operators to maintain the optimum completion diameter.
