THE BUSINESS OF OIL PRODUCTION EQUIPMENT INVOLVES THE LEADING ENTERPRISES OF THE SECTOR: Rimera-Service — provider of end-to-end service solutions for artificial lift wells in the major oil production regions of the Russian Federation: Nizhnevartovsk, Nyagan, Talinka, Noyabrsk, Muravlenko and Buguruslan Alnas — production of electric submersible centrifugal pumping systems for oil production. Izhneftemash — production of oil and gas equipment for drilling, completion and repair of oil and gas wells, as well as for oil production. 3 ABOUT RIMERA-SERVICE The service centers are located in the nation's major oil production regions. Extensive geographic coverage, state-of-the-art equipment, and highly skilled personnel combine to provide an unmatched service offering for production companies based on win-win partner- ships. One in seven production wells with electric submersible pumps operated in Russia is serviced by Rimera-Service. The company offers oil production companies a range of solutions using advanced technologies and state-of-the-art equipment. Alnas products are certified for conformance to Russia’s most rigorous quality standards. All equipment is available in customized configurations tailored to specific needs of customers. ESP AND SRP UNIT DOWNHOLE EQUIPMENT SERVICE AND LEASE • ESP unit size selection for operation in a specified well • Acceptance control, testing, revision, maintenance and overhaul of ESP unit assemblies • Onsite delivery of ESP units for installation and commissioning using own motor transport • Surface equipment repair • Preventive maintenance of surface equipment • Repair and setup of all types of ESP unit control stations and transformers • ESP unit assemblies follow-up, operation analysis, failure cause analysis • Equipment fault detection, mean-time-between-failures account by separate assemblies and their state MAINTENANCE AND OVERHAUL OF ESP UNITS Restoration of ESP unit operability, with up to 75% ESP components to be replaced (maintenance), or with over 75% working parts to be replaced with new ones (overhaul). Operations can be executed both within the service framework or under a repair work contract. SRP & PUMPING ROD MAINTENANCE AND OVERHAUL SRP disassembly, fault detection, re-assembly, equipment testing, and spare parts provision.

SRP lease term – 3 years 4 ABOUT RIMERA-SERVICE CONTROL STATION (VSD) REPAIR AND MODERNIZATION Case painting, application of graphic inscriptions & signs New module mounting in CS body CS testing SUPERVISING OF WELL SERVICING OPERATIONS Visual monitoring of well servicing team operations for well preparation and tripping operations with ESP units. TRAINING AND CONSULTATION ESP & SRP learning and operation training is provided by specialists in classrooms and in workshops. Methodological literature, operating manuals, stands displaying ESP & SRP parts, including cutaway view, are provided. Training classes are equipped with a well head model and a complete set of surface equipment (VSD and Step-Up Transformer) allowing to learn ESP unit mounting & installation, startup and steady-state flow process. Tubing services OCTG REPAIR, PREPARATION TO OPERATION, AND GATHERING In the process of work pipe preparation and gathering by customer requests is performed basing on the following parameters set: pipe schedule, strength group, length of suspension. The further completed suspension is delivered to the customer's field. In case of out-of-spec product supply, claims work with manufacturer and pipe repair are carried out. MANUFACTURING PRODUCTION ACCESSORIES FOR OILFIELD EQUIPMENT The following types of production accessories are manufactured: reducers (for transition from one pipe schedule to another), sleeves and landing joints of various lengths (for lowering submersible equipment to set depths). PIPE HANDLING AND STORAGE SERVICES The enterprise has a railway dead-end track with handling machinery (one-time unloading area of 850 tons). Opened and closed storage areas are over 27,000 m2. OTHER SERVICES Submersible equipment infield service includes equipment delivery, equipment follow-up, monthly report reception and verification, realization of equipment primary account, equipment repair. Supervising includes periodic inspection at contract organizations carrying out well repair, participation in accident investigation commissions, auditing, claims works. Tubing string lease for hydraulic fracturing and process operations allows contractors carrying out well repair to render these services to customers without acquiring an expensive equipment. 5 ABOUT RIMERA-SERVICE Well survey GEOTECHNICAL SURVEY In the process of work, drilling parameters and drilling fluid are monitored, content of hydrocarbons and other fluids coming from tapped strata are determined, cuttings sampling and sludge assay are performed, on-rig proximate wellcore analyses are performed. OPEN HOLE SURVEY The survey scope includes the following jobs: • Lithological differentiation of geological cross section exposed by electrologging • Reservoir bed identification • Reservoir bed fluid content identification • The rocks composing a geological cross-section have different specific electrical resistance depending on lithological structure and reservoir bed fluid content. Reservoir porosity and permeability properties identification. OPEN HOLE SURVEY DURING WELL CONSTRUCTION Complete well-logging operations provide geologic problem solving via three runs of nuclear logging tools and acoustic logging tools: • Lithological differentiation of geological cross section with its subsequent correlation • Reservoir bed identification • Reservoir properties assessment (porosity, shaliness, and permeability) • Reservoir bed fluid content estimation • WOC, GOC, GWC identification with subsequent perforation interval referencing For boring casing state examination, the acoustic cement bond logging, defectometry, thermometry, gamma defectometry and thickness testing, electromagnetic collar logging, electromagnetic testing, acoustic logging, and mechanical pipe profile logging are used PERFORATING-EXPLOSIVE OPERATIONS These include different-purpose perforating-explosive operations performed in deep wells with the use of blasting powders, brisants, and other explosives. Using explosions permits to control accident damage, to restore circulation, to break down, jar, twist off, shear a drill string, to break up and to occasionally recover metal pieces left in the hole, to prevent sticking, and to perform other operations, which are often quite specific. All kinds of works using explosives, such as perforation of strings, straddle packer setting, hole torpedoing, gunpowder pressure genera- tors, etc. PERFORATION (CABLE AND TUBING CONVEYED) Cumulative perforation provides hydraulic connection between a well and layer, i.e., perforation channel must break through the casing, cement ring, mud and grout colmatation area, and penetrate to a good part of the layer. TORPEDOING For accident elimination during boring, the following is made: • Boring tool sticking interval detection • Stuck pipe recovery by blasting methods • Break or cutting of tubing and
