2 COMPANY BRIEF HISTORY COMPANY BRIEF HISTORY About the company 23 in number, with the participation of OAO NPP VNIIGIS. Today, the company involves about 230 employees. Within NPF AMK GORIZONT there are electronics, design engineering, methods and software support divisions, as well as a field geophysical expedition, consisting of 15 geophysical crews, control and measuring instruments. The company has its own machine shop, metrology center, garage, production areas. Scientific potential and production facilities of NPF AMK GORIZONT allow operating in the market of geophysical services, applying the apparatus and method complexes AMK GORIZONT in the following areas: In 1990 in OAO NPP VNIIGIS a special purpose apparatus and method complex (AMK GORIZONT) was developed and tested in horizontal wells for the first time on the basis of drill pipe run self contained downhole equipment. To introduce into production and develop the drill pipe run technology of self contained well logging, in 1999 the research and production company AMK GORIZONT was set up by a group of research engineers and production workers development, manufacturing, supply, service maintenance, geophysical surveys of horizontal wells and side tracks by production crews. More than ten geophysical companies purchased apparatus and method complexes AMK GORIZONT and use them successfully in their business. Over the last years, several thousands of geophysical surveys were conducted in horizontal wells and side tracks in different regions of Russia, Kazakhstan, Uzbekistan and Ukraine. When logging in horizontal wells, we cooperate with more than 40 geophysical companies, realizing data interpretation together and making a conclusion about surveyed wells. Our logging crews make logging operations per month. To carry out a logging operation, we are ready for long range distances, and able to cover more than 5 6 thousand kilometers. The ongoing development and updating of self contained complexes, introducing new types of tools into well survey practice, mobility of our crews, timely fulfillment of work, and amiable partnership relations with geophysical companies guarantee a dynamic growth of OOO NPF AMK GORIZONT (Limited Liability Company). We are looking to cooperation. Best regards, Almaz Muzavirovich Sultanov, Director of OOO NPF AMK GORIZONT February ООО НПФ АМК ГОРИЗОНТ gorizont.ru 2

3 COMPANY BRIEF HISTORY LOGGING OPER ATIONS GEOGR APHY OPERATION TECHNOLOGY GEOPHYSICAL SURVEYS TECHNOLOGY The key aspect of logging with self-contained tools there is no possibility for realtime data recording. Therefore, data are recorded into different physical memory units. To implement this technology, there are a self-contained downhole tool, depth meter, load sensor and surface processing system within AMK GORIZONT. The technology of surveying horizontal wells and sidetracks with application of AMK GORIZONT comprises the following basic operations: preparation and testing of equipment at a well site; turn-on delay setting of measuring circuit of downhole tool delay or holding time; conveying the tool to the well head and mounting a container with ionizing radiation source into a special ; running the downhole tool on drill pipes up to the logging section; switching on the downhole tool power and recording geophysical parameters into the tool's memory; hoisting the tool to the surface, its disassembling and data reading from the selfcontained memory unit into computer (an information file); raw data processing and interpretation.
