ABSTRACT
Oil industry is a prominent aspect of modern economy and as it were exploration activities are very important for continuity of oil production.
The
exploration activities involve the acquisition of data and processing. As exploration activities increases in the
modern world, the computer manufacturers are also working hard to produce super
computer and their processing that are involved.
Many
firms are emerging fast and of course modern firms make use of computers,
especially the mainframe computer which has a large memory space. As the activities is in the increase, there
is need to increase storage facilities because there comes a time when the main
memory of computer will be unable to hold all information required. This is where the secondary storage device
called the magnetic tape comes to play.
A general
description of the system goals, facilities and applications are involved.
ORGANISATION OF THE WORK
The main aim of this project is to
show a practical approach to the exploration activities that involves the acquisition
of data and processing by companies where the processing and storage of
information (Seismic data) is done by computer.
In
the first chapter of this project, traces of the origin of seismic data
processing have been made. The problems
statement, the limitations, aims; objectives and purpose of the study have been
dealt with.
Chapter
two treats the review of the related literature work.
Chapter
three treats the description and analysis of the existing system. The oral interview for the research tools
used. The organization structure of the
company in question (IDSL) was looked into.
Also the objectives and problems of the existing system and the
justification for the new system were taken into consideration.
Chapter
four treats the design of the study that is the new system, as well as the
input, output specification and design, following the analysis of the dta
collected during the research study.
Also the new system requirement accompanied with the system flow chat
was considered as well as the procedure chat and file design for the new
system.
Chapter
five is all about the implementation of the new system design and testing of
the program with which the system is to be operated on.
Chapter
six is the documentation which was sufficiently completed to enable the user to
understand the essential characteristics of the system.
Chapter
seven is the conclusion dram from the entire study and the recommendation made
for further research.
Finally, the
appendices and references also the definition of terms.

CHAPTER ONE
INTRODUCTION
The exploration activities involve the acquisition of data
and processing. As exploration
activities increases in the modern world, the computer manufactures are also
working hard to produce super computers and their processing algo: thus with
high computing power to cope with the lager data processing that are involved.
Owing
to the inevitable roles that are played by the oil industries in the modern
world, the federal govt. recently issue out a white paper enforcing all oil
companies to do more exploration to increase oil reservoir. This means that there will be more data
acquisition and processing jobs in the near future.
The
importance of oil exploration in modern countries can never be our
emphasized. In the United States of
America and Britain, Intensive exploration activities are on for the last two
decodes all in a attempt to have enough oil resaves.
And
so seismic data processing is very indispensable in the oil industry because it
is the first step taken in the discoming of hydrocarbon or better more seismic
data processing is a key sequence in search for hydrocarbon.
In
the processing of seismic data, care should be taken because of not properly
processed, it might lead to wrong interpretation and this might lead to false
prospect. In fact wrong processing will
reduce the success ration in the discovery of hydrocarbon and this causes the
cost of drilling to increase. In
essence, wrong processing will lead to drilling false prospect and he know that
it costs millions if not billions of Naira to dill a well.
The
role of the govt. in oil industry had gradually progressed from a regulatory
one to direct involvement in all exploitation and exploration initially
government only made rudimentary laws and collected royalties four the oil
companies. By 1971 the situation charged
as oil become more important to the Nigeria Economy. Oil accounts for about 90% of the total
foreign exchange earning for the country.
In
essence, Nigeria that wants increase in her revenue, must engage in
acquisition, processing and management
of seismic data. Seismic data
management system is therefore a software development for the purpose. That is why the case study was the integrated
data services limited (IDSL) Benin city a subsidiary of the Nigeria Notional
Petroleum Cooperation (NNPC).
- PROBLEMS OF THE STUDY
In the search for hydrocarbon, the
initial question had always been where exactly under the surface are the
anticlines or the structures within which the hydrocarbon can be accumulated.
This question is answered in part by
seismic data acquisition and in the main by seismic data processing.
Acquisition semes the raw data while processing transforms and refines these
data to level where the above question is answered.
The problem is how can these information collected from the field be presented and protected from destruction. That is why the tape librarians were introduced to help in managing these tapes, but as time goes on the number of tapes acquired becomes so large in number that the librarians cannot manage then effectively. This has created many problem for the management.
The
solution to the problem will lie in removing any factors that inhibit the
ability of the librarian to make the storage and the retrieval of tapes easy in
the organization.
- PURPOSE OF THE STUDY
This research will be very useful to both students, individuals, co-operate bodies and general public as a whole who are either engaged or way wish to engage in seismic date acquisition and processing in the future.
The purposes are as follows:
Ensuring the acquisition of good quality seismic data in an effective manner.
Ensuring that all field tapes collected from the field are sent to the processing center and the its seismic data in the tapes are presented in a form that is convenient for geological interpretation.
To ensure that processing sequence are followed and a good result suitable for acceptance.
Ensuring that the processed seismic sections which is the final output of a processed field tape is used to identify specific areas for future field appraisal development.
