TOP COMPANIES FOCUSING ON EFFICIENT CONTROL OF EQUIPMENT AND IN IMPROVING THE QUALITY OF

DATA

WesternGeco - Schlumberger Tec hnology is the leader in the technology space with 824 patents filed in

the past five years. The focus of the company has been towards seismic data proc essing methods, removal

of ghost noises from the seismic data received, controlling the position of the seismic data equipment,

methods and apparatuses to conduct 3D and 4D seismic surveys. The other companies have focused its

research on the same lines.

INCREASING RESEARCH TOWARDS OBTAINING HIGH QUALITY & RELIABLE DATA

Though seismic equipment control which includes use of streamer positioning devices and improved

connections of seismic equipment by the use two or more seismic vessels are the key focus areas of the

companies, higher emphasis is laid on the data quality. The quality of data is improved by attenuating the

ghost signals reducing noise received by seismic receivers.

Some of the innovations for reducing ghost signals include:

Improvements in seismic source designs

Use of advanced common mid-point (CMP) methods for data gathering

Development of seismic sensors
