15 INTEGRATED EFFECT UNITS new 3. Integrated effect units AKV Plast-PP and GPM-105PP combine casing perforation by shaped charges with the subsequent propellant stimulation with combustion products of gas-generating charges in order to make additional micro-cracks in a well formation zone. Propellant stimulation includes integrated mechanical, physical-and-chemical and heat stimulations of the formation: Mechanical stimulation means making residual well fractures, cleaning of a well zone from chemical reaction products and sand-clay particles. At pressure kick liquid-gas mixture with high speed and under high pressure is pumped in the formation through perforation channels and natural cracks thus serving as a wedge forcing apart rock formation. Large amount of gas depending on the weight of gas-making charges provides pressure in the well higher than total rock pressure. Residual deformation of rock formation prevents healing after pressure release and makes unnecessary fixing cracks by sand or proppant that sets apart this method from hydrofrac. Physical-and-chemical stimulation with combustion products consisting mainly of carbon dioxide, nitrogen and chlorine hydride results in dissolution of carbonate rock and cement as well as in reduction of oil viscosity and surface tension at the boundary with water and rock. Heat stimulation results in melting of paraffin deposits and asphalt-resin materials as well as in viscosity reduction due to high temperature at the moment of burning of a solid propellant charge. Recommendations on application of LLC Promperforator integrated effect units. To provide maximum effect while using AKV Plast-PP and GPM-105PP it is recommended to conform application conditions for each well with LLC Promperforator specialists. Arrangement of AKV Plast-PP and GPM-105PP and calculated pressures are provided by LLC Promperforator specialists for each specific well on the basis of designed program. LLC Promperforator recommends a high-speed autonomous gauge used together with AKV Plast-PP and GPM-105PP for confirmation of calculated values. LLC Promperforator recommends a cable head NKPU.PP-65 used together with AKV Plast-PP (wire-line cable option) and GPM-105PP for reduction of peak loads on the unit, the casing and the cement stone during processing. 15

30 9. ACCIDENT ELIMINATION MEANS AND AUXILIARY EQUIPMENT Wire-line cable head catching tools LN-PP The line of catching tools is intended for removal of equipment from oil and gas wells after wire-line cable break at termination point. Main advantages of catching tools LN-PP: Design for the most frequently used typical sizes of cable heads 36 mm, 40 mm, 60 mm, 65 mm; Together with changeable bowls the cable head catching tools can be applied in casing pipes of any standard size; In case of accidental break of wire-line it is possible to drop extracted equipment; High reliability and long service life Fishing rods (wire-line catching tools) Fishing rods UV-PP and UN-PP are designed for removal of wire-line cable from oil and gas wells in case of its breakdown. Index UV-PP.01 Fishing rod design versions Diameter of removed wire-line cable Minimum casing drift diameter UV-PP mm 76 UV-PP UV-PP

31 Advantages of fishing rods UN-PP: Designed for mm diameter wire-line cable with possibility to cut the cable at excessive ultimate load; Universal fishing rod for casing pipes of any diameter (used together with bowls of different diameters); Maximum load 6 tons (limited by wire-line and cable head specifications); Wire-line cable assembly in a set; Service life from 30 lowering operations. Delivery set of the fishing rod includes assembler for cable compaction before removal Wire-line cable cutting tool KR-PP Wire-line cable cutting tool KR-PP is designed to cut wire-line in case of accidental stuck of the equipment lowered into the well with the wire-line. Advantages of KR-PP: The tool can be used on the cable with diameter up to 6,3 mm; Simple design and reliable operation starting from drop height of 1000 m; The main part of wire-line cable stays untouchable as the cable is cut at the point of stuck equipment; No need to pull the tool up to the well head as it stays together with the stuck equipment at the well bottom. Drop bar catcher LSH-PP Drop bar catcher LSH-PP is intended for catching and removal of a drop bar from a well after detonation. Advantages of drop bar catcher LSH-PP: Simple and reliable design; Designed for the most frequently used typical sizes of cable heads 36 mm, 40 mm; Easy release of a drop bar from the catcher after pulling operation. 31

Explosive packer VP Explosive packer VP is intended for installation of isolation bridges in cased sections of exploratory, production and injection wells. Explosive packers are used in wells filled with liquid (water, flushing fluid, oil) at hydrostatic pressure up to 60MPa and temperature up to 120 C.

33 ACCIDENT ELIMINATION MEANS AND AUXILIARY EQUIPMENT Heat Resistant Primer Torpedoes THT THT torpedoes are designed for drill pipe break-off during emergency response (THT 25 /28 THT 84/90) and for shot-firing operations in cased wells and wells where the productive formation is not cased off, to increase flow rate and wells intake capacity (THT 35 /40 - THT 84/90). Torpedoes are used in wells filled with flush fluids at hydrostatic pressure of 100 MPa and temperature up to 160 С. Torpedoes run into the well with a single-core armoured cable.
