URBAN & AGRICULTURAL AREASrespecting local communities

GT has adequate resources and extensive experience

to successfully acquire seismic data in urban, industrial

and agricultural areas. They are particularly

challenging endeavors as seismic crews have to face

concerned residents, local access restrictionsand

ongoing farming activities. The company employs the

latest state-of-the art technology and proven practices

that result in excellent imaging low impact surveys and

preserve clients “good neighbor” status. With the use

of wireless ultra-light nodal systems, GT is able to push

the boundaries of seismic method, where urban,

agricultural or environment related challenges have to

be faced. With this approach, ultra-light equipment

on-site results in lower HSE exposure and local

footprint, without compromising on sensing

performance.

Gt’s specifi c approach in this fi eld includes:

information campaigns prior to and during field operations to secure support of localcommunities

application of various types of vibroseisincluding minivibs and wireless data acquisition systems to minimize survey footprint

onsite PPV monitoring to assure safe data acquisition in residential areas and nearby ancient sites

vehicle monitoring system to minimize transportation hazards

strict HSE approach to ensure that no harm is done to either people, third party assets or the natural environment

GT’s mission has always been to provide

professional and innovative geophysical

services in a manner that guarantees respect

for the natural environment. While shooting

seismic around the globe, the company’s

seismic crews have come across some of the

earth’s true wonders. No matter whether it

comes to a national symbol or a small area

cherished by local citizens, GT ensures that

the impact of seismic operations is kept to a

minimum through implementation of a series

of measures, including:

ENVIRONMENTALLY PROTECTED AREASpreserving the natural environment

survey schedule adapted to environmental restrictions such as bird breeding seasons

encouraged engagement of environmental authorities in both survey planning and execution

personnel urged to take extra cautions when approaching biotopes and other sensitive areas

application of alternative energy sources in case of restricted access for heavy equipment

employment of inertial surveying technology for forest areas with insufficient GPS coverage

GT has experienced teams and field-proven

technology to make even the most

challenging desert surveys successful. Its

solutions can be the answer not only to the

terrain & weather challenges, but in

particular complex subsurface conditions

such as highly variable low velocity zones.

The company's crews can deliver high quality

imaging and required resolution in set time

limits in challenging sand dunes, buried

wadies or sebha deposits. GT can overcome

desert prospecting challenges with the

advantages that include:

Apart from onshore areas, GT successfully

executes seismic field operations in

challenging transition zones. The company’s

hybrid acquisition system technology

comprises of a mix of vibroseis, explosives,

a i r - g u n s m o u n t e d o n c u s t o m - m a d e

hovercraft, hydrophones, marsh phones, land

geophones, and optical data transmission

devices. All this equipment bridges the gap

between land and water. As a result, GT is

capable of professional seismic imaging on

hardly accessible water bodies.

seismic data processing

DELIVERING INNOVATIVE SOLUTIONS

Scope of services:

GT provides advanced processing and imaging of both

onshore and offshore seismic data. Its extensive

experience covers various corners of the globe,

including Europe, South-East Asia, Africa, South

America and the Middle East. GT’s close-knit team has

rich problem-solving experience enabling to propose

fit for purpose solutions that best suit E&P companies’

exploration goals. We employ an extensive portfolio of

technologies and workflows tailored to the specific

challenges of land and marine data, including

innovative proprietary tools specifically designed to

solve imaging problems.

Processing packages dedicated to:

marine & TZ seismic data processing

land data processing

ime and depth domain imaging, incorporating gravity data into the model building procedure

2D and 3D VSP data processing

QC and Fast Track for acquisition projects

C-waves data processing

Structural and litho-facial surveys

Unconventional hydrocarbons

Geothermal reservoirs

Deposits of lignite, copper and sulfur

Underground storages

Scientific research projects

GT’s processing team is aware that obtaining

the best results for challenging datasets

requires out-of-the-box approach leading to

bespoke solutions. It is often the case that high-

quality results can only be achieved through

time-consuming interactive solutions, instead

of standardized automated procedures. GT's

highly skilled team of geophysicists is invaluable

in cases where complex near-surface geology

require the application of advanced techniques

in the range of: static corrections, noise

elimination, wavelet processing or model

building.

In-house team is capable of delivering seismic

datasets of unrivalled quality thanks to

state-of-the-art as well as innovative

proprietary software tools. R&D ideas are

derived from the challenges of day-to-day

production and the increasing need for tailored

solutions. Some of the new processing

techniques, which have only recently been

found very successful by the clients, include:

ECP (multi-attribute processing), IWS

(interactive wavelet shaping) and MulFIP

(multifactor interactive processing).
