Save to read list Published by David Bizley, Editor Oilfield Technology, Thursday, 21 September 2017 09:00 Weatherford International plc has announced the commercial release of the ISO Extreme retrievable well barrier, which is qualified to ISO 14310 V0 standards for gas-tight isolation. The barrier has a large operational envelope: it is capable of withstanding pressure differentials up to 10 000 psi (68.95 MPa) and temperatures between 40 and 325°F (4 and 163°C), which reduces the loss-of-containment risk in extreme environments. ISO Extreme well barriers are available for tubing sizes from 3.5 through 7 in. The variety of deployment options — including electric line, slickline, tubing and coiled tubing — further increases operational flexibility. Unlike comparable technologies available for the high-pressure, high-temperature (HPHT) market, the ISO Extreme barrier does not require any nipple profiles and is retrieved by first shifting down to equalise the pressures then jarring up to release. This safety feature reduces the risk of trapped pressure below the plug prior to releasing. Additionally, the small diameter of the plug enables passage through typical wellbore restrictions for easy deployment and removal even in challenging environments. “We are pleased to add the first V0-qualified and field-proven HPHT well barrier to our industry-leading portfolio of wellbore isolation technologies,” said Mark Hopmann, Vice President of Completions at Weatherford. “With this addition, we now have a comprehensive offering of well barriers for diverse applications and environments.” Read the article online at: https://www.oilfieldtechnology.com/drilling-and-production/21092017/weatherford-introduces-v0-qualified-retrievable-well-barrier/ A Rystad Energy analysis shows that Canada is the oil producer most affected so far by the slump in global oil demand, with the damage estimated to reach above 1.1 million bpd in shut-in production in 2Q20.

ISO Extreme has released its Weatherford International retrievable well barrier. The V0-qualified barrier can operate in temperatures between 4C and 163C, withstands pressures up to 10,000 psi, and can be deployed via slickline, electric line, tubing and coiled tubing. Weatherford also said the Weatherford International barrier does not require nipple profiles and is easily retrieved.
