Authors:

Abstract

The ultimate goal in oil and gas exploration is discovering new resources and finding new reserves. GIS Technology provides important tool for evaluation of potentiality of reserves and their locations. Oil and gas exploration operations are always depends on number of complex Geological operations. From seismic exploration and placement of seismic lines onshore as well as offshore to exploration of various subsurface geological conditions in order to provide detailed overview for underneath resources, which requires dealing with large volumes of complex data. Discovering feasible reserves is a core competence to be successful in the petroleum industry. GIS thus is very important technology for evaluation of the potential for oil and gas in promising location. GIS Technology provides advanced capabilities in spatial analysis and visualization of surface and subsurface geological and geophysical data. These analysis and visualization capabilities help with efficient and effective evaluations of prospects in potential zones. This presentation introduces the vast capabilities of GIS and its application in the petroleum industry. It provides an emphasis on the spatial extent and the portions of exploration and production operations that can effectively utilize GIS.

Conclusion
No doubt many readers will agree that GIS - particularly in the context of
petroleum exploration and development - is one of those technologies that is
hard "to get one's arms around." At least part of the reason is the absence of a
standard definition of just what a GIS is and what it's supposed to do.

GIS Applications in Petroleum
Geology
The petroleum is the most important and foundational
energy in the world at present.
It is also the most capital intensive. Revenues are
large, as are the costs.
It also makes headlines for unforeseen accidents and
environmental hazards.
The ever changing dynamics of this industry drives
sustained efforts for increased efficiencies and risk
mitigation.
The petroleum business requires the handling and
analysis of different types of data, which can be
subdivided:
a) into unstructured data such as reports inside a document management system.
b) structured data in databases, and spatial data available from GIS.
GIS Applications in Petroleum
Geology
The Oil and Gas industry is driven by an estimated
80% data that has a spatial component.
This is the only industry that harnesses spatial
information at every stage of the life-cycle, beginning
with opportunity analysis and exploration, through
appraisal and production, right up to the abandonment
phase.
So companies are beginning to understand the
importance of geospatial to maximize ROI as well as
minimize risks.
GIS for Petroleum
Discovering new sources of petroleum ahead of the
competition is one of the key ways to stay successful
in the petroleum industry.
A GIS system can help you evaluate the potential for
oil in promising locations.
Exploration often requires analysis of satellite imagery,
digital aerial photomosaics, seismic surveys, surface
geology studies, subsurface and cross section
interpretations and images, well locations, and existing
infrastructure information.
GIS for Petroleum
A GIS can relate these data elements to the
location in question in map form and allow
you to overlay, view, and manipulate the data
to analyze and understand its potential.
GIS technology today allows you to manage
the spatial components of these everyday
petroleum business objects, such as leases,
wells, pipelines, environmental concerns,
facilities, and retail outlets, in the corporate
database and apply appropriate geographic
analysis efficiently across the enterprise.
Application of GIS in Petroleum
Exploration
The oil and gas exploration collects a large
quantity of data; most of them are based on spatial
geographic position.
GIS is used to manage, inquiry, analyze, and
visualized data; all of the data, figures and
information are managed integrated.
Spatial elements can be formed by these spatial
data with GIS, all of the data will be integrated in
a platform of a uniform database.
By the strong ability of the spatial analysis, an
effective analysis will be done.
It is a new applied character of combining the GIS
with the technology of oil and gas exploration in
the field of petroleum exploration.
Application of GIS in Petroleum
Exploration
The management in petroleum exploration
by GIS includes :
build a database to manage the data of oil
and gas exploitation, such as logging data,
drilling data, and experimental analysis etc
integrate all of the data mentioned above to
detailed describe the stratum layer, litho
logic characters, and tectonic structure of
the oil reservoir.

Benefits of GIS in Oil and Gas
Empowers Decision-Making
Which acreage or play to enter, how to shorten
portfolio workflows, how to plan the optimal
pipeline route, integrate results of seismic survey,
planning emergency response, better management
of facilities, manage pipeline outage and leaks, etc.
Benefits of GIS in Oil and Gas
Supports future action and ongoing
exploration activities
By standardizing processes and reducing
technical uncertainty, GIS improves
exploration efficiency. The GIS framework
models a consistent exploration processes
across all assets within the company. This
supports a consistent, auditable corporate
prospect portfolio, for ongoing portfolio
decisions.
Benefits of GIS in Oil and Gas
Increased Efficiencies
Multi disciplinary data integration for risk
assessment and uncertainty, better access
for cutting wasteful downtime, optimized
maintenance schedules; monitoring and
analysis of daily fleet movements in real
time, least cost path analysis for pipeline
routing, standardized portfolio workflows,
cutting down decision cycle times, etc.
Benefits of GIS in Oil and Gas
Cost Saving
An estimate of 10-30 per cent cut in
operational costs, prevention and management
of incidental or accidental costs, efficient
pipeline and fleet management saves costs,
optimized drilling and operation workflows
enhances ROI, and so on.
Seamless Management
with a real-time mapping visualization and
analysis of remote /offshore sites, operations
and assets.
Benefits of GIS in Oil and Gas
Improved Communication
Across spatially dispersed locations
Record Keeping
The huge data loaded in centralized GIS
builds a strong framework for managing
data with full transaction support and
reporting tools.
Uses of GIS in Oil and Gas
Data Index Maps
One of the most common uses of GIS in the petroleum
sector is in delivering easy-to-use digital maps that
enable oil company staff to see what data is available
to them, so that they can drastically reduce the amount
of time they spend looking for the information they
need to do their work.
Often such maps are delivered using web-based GIS
applications that require little or no training to use, and
show all data of interest side-by-side in a single
interface.
Uses of GIS in Oil and Gas
Emergency Response
GIS is becoming increasingly important in
response to emergencies such as oil spills and
gas explosions, both in mitigation planning and
response management.
Data loaded into a GIS can be made available
to all stakeholders regardless of their physical
location (e.g. to workers in the field on mobile
devices), and even to the public.
This leads to better decision making during
emergency response situations, and improved
public relations.

Uses of GIS in oil and gas
Pipeline Monitoring
Pipelines need to be continually monitored to check
for leaks and geo-hazards, and to manage and track
inspections, the frequency of which is often a
regulatory requirement.
An emerging use of GIS is in integrating the map with
digital video, often acquired using remote vehicles on
the seabed, enabling engineers to see sections of
pipeline and monitor hazards affecting the
installation.

Uses of GIS in Oil and Gas
Block Ranking
Ranking opportunities via quantitative analysis using
all available information require data integration on a
massive scale, and so it is usually seen as too time
consuming to carry out on a regular basis.
GIS provides the perfect environment in which to
rapidly evaluate and grade oil and gas licenses or lease
blocks.
It provides a unique way of mining large quantities of
different types of data in order to help make a decision,
and many companies employing GIS for this analysis
believe that it gives them a competitive edge.

Conclusion
The Oil and Gas industry has been a comparative late
comer to GIS. However, it is fast emerging as the industry
with the highest potential of GIS application through the
entire life-cycle.
Whats more, it enables a seamless integration of
geospatial technologies like UAV, sensors, and existing
computer systems within the GIS framework.
This is helping companies compete in the global race to
unlock new energy sources and maximize value from its
