Packers systems are among the most important tools in the tubing string. The types of packer systems vary greatly. Often, they're designed or configured to meet specific wellbore or reservoir conditions, such as single-packer or tandem-packer configurations, single-tubing or dual-tubing strings, and the full range of pressure and temperature applications.
The basic requirement of packers systems and associated tools relates to flow from or injection into the formation to the tubing string or production conduit. The packer must enable efficient flow and must not restrict normal production or injection flow.
All new packers are designed and tested to ISO standard 14310, which defines packer design validation grades. Premium packers are qualified as V0, the strongest validation overall, and new packer designs must meet the minimum standard of V3, the most stringent standard for testing in liquid media. In addition to the standard ISO testing, packers undergo design acceptance tests, including vibration and shock testing, standard flow-by testing, mill-up verification testing, and functional testing to failure. All X-series elements are 100% volumetrically scanned.
