Packer Systems<strong>ECV</strong> <strong>Storm</strong> <strong>Valve</strong><strong>Weatherford</strong>’s <strong>ECV</strong> storm valve is run above the DLT compressionsetservice packer or CSTH storm packer to isolate the tubing belowthe packer for disconnection during a weather emergency or surfaceequipmentrepair.The valve has a J overshot running tool, which a quarter turndisconnects. This quick, safe, cost-effective well closing requiresno tubing pulling. The valve can be repeatedly opened and closed,independent of the disconnection feature, enabling packer-pressuretesting before disconnection.The heavy-duty bearing assembly enables free valve operation with therunning string in compression, easing operation on floating rigs. Beforepacker retrieval, the string can be reconnected and the valve opened toequalize pressure.Applications• Weather emergencies• Wellhead repairFeatures, Advantages and Benefits• The rugged alloy-steel construction ensures dependability.• The internal-flush (IF) drillpipe tool-joint thread connections provideexceptional, field-proven torsional strength for rigs.• The simple, field-proven design eases valve operation and redressing.• The J-tool disconnects with a quarter turn of the running string,providing fast, efficient valve placement.• The valve can be opened and closed repeatedly with two quick turns,independent of the disconnection feature, enabling the packer to bepressure tested before disconnection to ensure its integrity.• The expandable plug provides through-bore access for circulation andwirelines.<strong>Weatherford</strong> <strong>International</strong> Ltd.515 Post Oak Blvd., Suite 600Houston, Texas 77027 USATel: 713-693-4000weatherford.com© 2007 <strong>Weatherford</strong>.
