Wisting Central II

OMV has successfully completed drilling and testing of the Wisting Central II appraisal well. The horizontal well was drilled in the Wisting discovery in the Barents Sea, about 310 km north of Hammerfest. Wisting is the northernmost oil discovery in Norway. Wisting Central II is the fifth well in the production license PL537, which was awarded in the 20th licensing round in 2009. The planning and execution of the well was done in close co-operation with various parts of the Schlumberger organization.

MPD allows for dynamic well control offshore

When drilling offshore – particularly in deepwater – the distance between the BOP on the seafloor and the rig can potentially leave the riser, as well as the rig, exposed to kicks. “If, for example, an influx or a kick gets past the BOPs, it can travel up the riser. As it gets closer to atmospheric pressure, it can then unload at an exponential rate, causing danger to the personnel, the equipment and of course the environment,” said Guy Feasey, VP of Well Integrity at Weatherford. Managed pressure drilling (MPD) can account for these influxes. It can also provide drillers with additional options on how to deal with these influxes, aside from simply shutting in the BOP. Watch the video with Mr Feasey from the 2016 IADC World Drilling Conference in Lisbon to learn more about how MPD can enable dynamic well control.
