ABS, partners test Polar Code requirements through search and rescue exercise offshore Norway

In April, ABS partnered with the Norwegian coast guard, academic institutions and other stakeholder companies to perform a search and rescue exercise in Svalbard, Norway. The University of Stavanger, Company GMC and the Norwegian Coast Guard organized the exercise, which took place on the K V Svalbard, a Norwegian Coast Guard vessel. The exercise was conducted to gain a better understanding of the IMO Polar Code’s requirements, which many in the industry regard as vague, according to ABS. For example, the code requires the crews of maritime vessels, including drilling rigs, to be equipped be able to survive five days in polar waters while awaiting rescue. There was concern about whether this was even possible with existing equipment, said ABS ...

Petronas implements enterprise-level real-time data management infrastructure

Petronas implemented the Real Time Well Solution, an enterprise real-time data management solution with web-based delivery, in 2014. The data management infrastructure is helping the operator to better manage its rig-site drilling operations from remote locations.

Although Petronas had established its Smart Drilling Optimization Monitoring Centre (Smart DOMC) in 2010, the operator decided in 2014 to change its approach to rig-site monitoring. “At that time, the environment of the real-time (monitoring) was fully managed by a service company, so we felt that we didn’t have control,” Noorazmah Yusoff with Petronas said in a presentation at the 2016 IADC/SPE Asia Pacific Drilling Technology Conference, held 22-24 August in Singapore. “We wanted to have more control of the data, from the location portion up to the integration portion of it.”

OMV finishes Wisting Central II appraisal well

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

Screen Shot 2016-06-21 at 11.59.12 PM

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.
