DESIGN AND MANUFACTURING OF PERFORATING SYSTEMS

Promperforator LLC has been operating in the perforation systems market since 2002.

The Company’s basic sphere of activity is the development and manufacture of perforation systems, and the integrated supply of commercial explosives and equipment for perforating-explosive operations in oil, gas and metal mining industries.

The Company has all necessary licenses and permits for performing activities such as production, distribution and storage of commercial explosives.

The main production plant is located in Chapayevsk, Samara region.

Promperforator LLC production is applied in the following cases:

• casing perforation of oil, gas and other formatiions;

• perforation of oil and gas wells under pressure;

• preparation works for formation hydrolic fracturing;

• remedial cementing;

• elimination of accidents in wells.

Use of modern technologies provides reliability, safety and high quality of our production.

All perforation systems and components come with permanent operational permits from RF Rostekhnadzor, as well as conformity certificates.

All our charges have passed certification tests under the Russian procedure SS-05, as well as international procedure API RP 19B for perforator tests.

With the aim of diversification, we are in constant consultation with geophysical and oil companies and invest in our own development. The Company’s technical department is responsible for all issues concerning specific use and technical data of perforating systems, as well as drafting new projects.

High production capacities allow us to have end products in stock in warehouses available at any time, which ensures timely delivery.

DESIGN AND MANUFACTURING OF PERFORATING SYSTEMS

The central warehouse in Chapayevsk has a geographically advantageous location, which provides for quick delivery. Apart from the central warehouse, the Company has two consignment warehouses in Nizhnevartovsk and in Noyabrsk, Western Siberia.

Delivery of production to Customers’ warehouses is performed by road as well as by railway and by air.

Fair price policy, flexible payment system and strict observance of contractual commitments enable us to successfully cooperate with the biggest geophysical and oil companies in Russia and the CIS.

Promperforator LLC’s customers include such companies as OJSC Gazprom, OOO Gazflot, OJSC TNK-BP, OJSC Surgutneftegaz, OJSC Tatneft, OJSC Bashneft, OJSC NK Rosneft, OOO LukOil, OJSC Russneft, АО Kazmunaigaz, OJSC Gazpromneft, Azerbaijan oil company SOCAR, PC Ukrgazdobycha and many others.

Scalloped Gun Perforating Systems KP050, KP064, KPO73, KPO89, KPO102, KPO114

Scalloped gun perforating systems KP050, KP064, KPO73, KPO89, KPO102, KPO 114 are used in perforating-esplosive operations in oir, gas and other wells both at low and high hydrostatic pressure with t° up to 170°С.

All KPO perforating systems have similar structure and differ only in overall size. Small-size perforation systems KP050 can be used with coil-tubing. It is provided to apply centralizers for optimum location of perforator towards casing walls (it does not refer to KP050 due to its use with coil-tubing).

KPO Perforating Systems can be used in vertical, directional and horizontal wells with both wireline and coil-tubing.

Specific features of KPO perforating systems:

• Simplicity, convenient and quick loading of the system both at the loading shop and in work area;

• High operation reliability of multicarrier perforator due to special design of detonation transmission unit;

• Convenient connection of separate sections of perforator at well-head due to the use of buttress thread and reliable fixation of perforator at well-head;

• Operating capability under conditions of high temperature and high pressure in wells;

• Adaptation for all initiating systems;

• No well clogging. 100% of perforation equipment and materials are extracted from the well after perforating;

• Minimum deformation of carrier at explosion;

• Possibility to use DP and LH charges in one gun (combined perforation);

DESIGN AND MANUFACTURING OF PERFORATING SYSTEMS

Perforating system KPO Combined DP+LHThe combined perforation refers to joint usage of «Deep Penetration» and «Large Hole» charges in the same gun.

It is offered as optional, at the Customer’s request, as a fairly universal variant at well completion. It may be used both for hydraulic formation fracturing and for standard perforation. Our enterprise has a wide range of perforating systems and shaped charges that allows us to successfully undertake operations on exposing a producing horizon using the combined perforation method.

Manufacturer's Certification

Type of certification: x Sel Third Party

I certify that these tests were made according to the procedures as outlined in API 19 B: Recommended Practice for Evaluation of Well Perforators, Second Edition, September 2006. All of the equipment used in these tests, such as the guns, jet charges, detonator card, ect., was standard equipment with our company for the use in the gun being tested and was not changed in any manner for the test, Furthermore, the equipment was chosen at raudom from stock and therefore will be substantially the same as the equipment that would be furnished to perforate a well for any operator. API neither endorses these tests nor recommends the use of the perforator system describes.
