2D/ 3D Seismic Data Acquisition

The Center of Reliable seismic

Introduction

SMNG-Center, a leading provider of marine geophysical services

in Russia, headquartered in Moscow, was founded in 1996.

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 quali�ed 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.

Seismic Instruments

SMNG-Center is pleased to o�er to

the clients the most advanced seismic

solutions in the industry.

The company operates the following

seismic tools and equipment:

- Su�cient number of �eld electronic equipment (LCI, LAUL, LAUX, Trep, etc.)

- Sercel 428XL software license

- Sercel SQCpro software license

- 2,800+ Sercel 428XL channels

- 1000+ Sercel 408 ULS channels

Based on this same highly e�cient 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 o�ers all new hardware and software which is speci�cally designed to meet the needs of large channel count operations while improving conventional operations. It is also compatible with the 408ULS and 408UL �eld equipment. (refer to www.sercel.com)

- High rate on lines (16 Mbps) and Transvers (100 Mbps)

- Improved capabilities (up to 100,000 traces real time @2 ms)

- Client server architecture

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 http://www.iongeo.com/ )

Receivers on the seabed are

positioned with Sonardyne

TZ/OBC equipment. (please refer to http://sonardyne.co.uk/)

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. pinged.

Where possible, both

Sonardyne and INS Gator are

capable of adjusting the

positions using !rst break

arrivals.

Gator is designed to meet the

unique challenges of

distributed, multi-vessel

seabed operations, such as

ocean-bottom cable (OBC)

and transition zone

Operation in Shallow water and Transition zoneSeismic 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.

Purpose-designed catamarans

carrying necessary equipment

and high-accuracy positioning

systems are used to deploy

receiver lines in waters

depths up to 50 m.

ATV "Rosa" running on

low-pressure tires shows excellent

performance on marshes and

lakes. Its Diesel engine ensures

smooth motion in any operating

mode.

Seismic Source Vessels

This ship was fully

repaired in 2009 in

Bremerhaven

(Germany).

The ship was repaired at the same shipyard where she was built in 1983.

During the repairs, new seismic equipment was installed (compressor,

airguns, source controller).

GEO-12 module-design

vessel was speci!cally

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.

Source vessel "Skat" is

utilized for seismic

acquisition in water

depths of 2.5 m and

deeper.

Seismic Data Processing and Interpretation

A powerful IBM 112-processor cluster

supports all stages of 2D and 3D seismic

data processing.

There are 17 highly professional geophysicists in the processing center

involved in the processing and interpretation of 2D/3D seismic data.

SMNG-Center o!ers 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.
