Weatherford has been awarded an Innovative Technology Agreement with ENI to develop a subsea drilling-with-casing (DwCTM) system.
This technology agreement is aimed at realizing the benefits that a proven technology like the DwC system can offer, including mitigating shallow hazards, in a previously non-applicable and costly subsea environment. In doing so, this system will minimize risk while allowing maximum flow area to be maintained.
Ultimately, the SeaLance system will allow the remaining casing seats to be pushed deeper into the wellbore. This technology advancement will further enable applications in sub-salt plays.
