Scientific and production company “ALTERNATIVE TECHNOLOGIES”, CJSC Russia, Novosibirsk region, Koltsovo, 14 Tel./Fax: (383) Technology for production of a compact reusable multifunctional valve (packer) for maintenance and repair of oil and gas wells without using damaging pipes fasteners. © Innovation center Koltsovo, 2012 Autonomous non-profit organisation “Innovation center Koltsovo” Novosibirsk region, Koltsovo Technoparkovaya 1, office Tel./fax: +7 (383) , web:

Description of the technology The designed packer is reusable. It can be hydraulic or hydro mechanical. The packer is fixed in a tube due to a patented method of fastening without anchors. It can be easily removed from the well and repositioned there without damaging the pipe. The device size may range on request, from 146 to 295 mm (casing string size dependent). The working pressure can be increased from 100 to atmospheres. The packer reacts to pressure drops directed downwards and upwards mm weight: kg

Applicability of the technology in Kazakhstan Packer can be use during well drilling, as a valve in an open borehole. For all types of repair work in the column, including: repair of vertical, downhole and horizontal oil/ gas wells, detection of leakages, acid treatment of formations, pressure testing of casing pipe and location of leakages, pressure testing of the oil compressor pipes. In case of hydraulic fracturing. For completion of wells. The original design allows for following advantages: 1.FIXATION WITHOUT ANCHOR 2.MULTIPLE USE 3.MULTIFUNCTIONALITY 4.Allows for INSTALLING AT ANY TYPE OF WELL, 5.Allows for INTERVAL EXAMINATION OF HOLES IN ONE SET 6.SIMPLE IN USE The technology have 3 Russian patents granted in 2007 and The prototype had been successfully tested at the field well of “Tatneft”, OJSC in 2011 (Tatarstan, Russia) The prime cost of the proposed packer is less than of analogues, due to small size and simplicity of construction. No additional fasteners are required: the packer does not cause functional loss or damage to the casing pipe walls and it can be reused. Multi-functionality eliminates the need for different types of specialized packers. These factors are reduce time and costs of repair / service. We are looking for a company that can purchase our technology: Oil companies active in supply and repair of equipment, well construction, etc.; Service companies working at oil fields.
