Introduction SMNG-Center, a leading provider of marine geophysical services in Russia, headquartered in Moscow, was founded in 1996.

SMNG-Center utilizes newest seismic and positioning equipment, employs highly qualified professionals, which ensures the highest quality of the collected data meeting the most stringent industry

2 Introduction SMNG-Center, a leading provider of marine geophysical services in Russia, headquartered in Moscow, was founded in The company specializes in the following areas of expertise: - 2D and 3D seismic data acquisition in deep, shallow water and transition zones using state-of-the-art Sercel OBC equipment. SMNG-Center utilizes newest seismic and positioning equipment, employs highly qualified professionals, which ensures the highest quality of the collected data meeting the most stringent industry standards. - 2D/3D Seismic Data Processing For seismic data processing, SMNG-Center uses software solutions developed by such leading providers as Landmark, Tsunami Development, Paradigm Geophysical. - 2D/3D Seismic Data Interpretation Landmark and Hampson-Russell software is used for seismic data interpretation.

) - Sercel 428XL software license - Sercel SQCpro software license - 2,800+ Sercel 428XL channels - 1000+ Sercel 408 ULS channels Based on this same highly efficient design as 408UL, the 428XL

3 Seismic Instruments SMNG-Center is pleased to offer to the clients the most advanced seismic solutions in the industry. The company operates the following seismic tools and equipment: - Sufficient number of field electronic equipment (LCI, LAUL, LAUX, Trep, etc.) - Sercel 428XL software license - Sercel SQCpro software license - 2,800+ Sercel 428XL channels Sercel 408 ULS channels Based on this same highly efficient design as 408UL, the 428XL requires less power, lasts longer, and is more reliable than any of its competitors on the market today. The 428XL offers all new hardware and software which is specifically designed to meet the needs of large channel count operations while improving conventional operations. It is also compatible with the 408ULS and 408UL field equipment.

4 Navigation Equipment INS Gator by Concept Systems Ltd. is used for positioning. The central data management and advanced positioning functionality have made Gator the leading navigation and seismic control system in the market today. (please refer to ) Receivers on the seabed are positioned with Sonardyne TZ/OBC equipment. (please refer to This equipment is also integrated into the INS Gator, which allows to quickly locate accurate positions of the receivers after they have been deployed on the seabed and pinged. Gator is designed to meet the unique challenges of distributed, multi-vessel seabed operations, such as ocean-bottom cable (OBC) and transition zone Where possible, both Sonardyne and INS Gator are capable of adjusting the positions using first break arrivals.

5 Operation in Shallow water and Transition zone Seismic data acquisition in extremely shallow waters and transition zone is the most complicated operation since it involves a lot of personnel, equipment and vehicles. These operations are often performed in very harsh and remote environments. Receivers in transition zones are deployed using special-purpose all-terrain vehicles (ATVs), boats, or even by hand. ATV "Rosa" running on low-pressure tires shows excellent performance on marshes and lakes. Its Diesel engine ensures smooth motion in any operating mode. Purpose-designed catamarans carrying necessary equipment and high-accuracy positioning systems are used to deploy receiver lines in waters depths up to 50 m.

6 Seismic Source Vessels Source vessel "Skat" is utilized for seismic acquisition in water depths of 2.5 m and deeper. This ship was fully repaired in 2009 in Bremerhaven (Germany). The ship was repaired at the same shipyard where she was built in During the repairs, new seismic equipment was installed (compressor, airguns, source controller). GEO-12 module-design vessel was specifically built for operations in extremely shallow waters. Her fully-loaded draft is just 0.6 m. The ship carries a HP compressor and an AC generator. She is capable of towing two air gun sub-arrays totalling 440 cu. in. at a speed of 5 knots, which results in a fast acquisition of seismic lines in extremely shallow waters, such as transition zones, lakes and rivers.

7 Seismic Data Processing and Interpretation There are 17 highly professional geophysicists in the processing center involved in the processing and interpretation of 2D/3D seismic data. A powerful IBM 112-processor cluster supports all stages of 2D and 3D seismic data processing. SMNG-Center offers a full range of processing and interpretation procedures. A huge experience in processing shallow water and TZ data was gained in applying the following procedures: 1. Noise attenuation over 3D cross spread using 3D FKxKy 2. Longway static correction 3. Residual static calculation The application of 3D interpretation, 3D visualization, and seismic inversion provides more detailed images of potential reservoirs and allows to predict their petrophysical properties.
