Expandable-tubular solutions
A method has been developed to expand the diameter of solid tubulars downhole. This technology provider cost-effective solutions to several tubular problems that have presented obstacles to comprehensive reservoir exploitation. Operators can use smaller holes to drill deeper vertical wells or to extend the reach of deviated wells to access untapped reservoirs. In older fields, existing well-bores can be repaired with expanded tubulars or their tubular strength and integrity can be increased.
