DESIGN & IMPLEMENTATION OF A COMPUTERIZED INFORMATION MANAGEMENT SYSTEM IN SEISMIC DATA PROCESSING

ABSTRACT

The oil industry is a prominent aspect of the 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, computer manufacturers are also working hard to produce. Supper computer and their processing that are involved. Many firms are emerging fast and of course, modern firms make the use of computers, especially the mainframe computer which has a large memory space.  As the activities are in the increase, there is a need to increase storage facilities because there comes a time when the main memory of the computer will be unable to hold all the 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 application are involved.

CHAPTER ONE

1.1              INTRODUCTION

The exploration activities involve the acquisition of data and processing.  As the exploration activities increases in the modern world, computer manufacturers are also working hard to produce supercomputers and their processing algo: This with high computing power to cope with the lager data processing that is involved. Owing to the inevitable roles that are played by the oil industries in the modern world, the federal govt.  recently issues out a white paper enforcing all oil companies to do more exploration to increase oil reserver.  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 overemphasized.  In the United States of America and Britain, intensive exploration activities are on for the last two decades all in an attempt to have enough oil reserves. And so seismic data processing is very indispensable in the oil industry because it is the first step taken in the incoming hydrocarbon or better more seismic data processing is a key sequence in search of hydration. 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 knows that it costs millions if not billions of Naira to dill a well. The role of govt. the 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 for the oil companies.  By 1971 the situation changed as oil become more important to the Nigeria Economy.  Oil accounts for about 90% of the total foreign exchange earnings for the country. In essence, Nigeria that wants an increase in her revenue must engage in the acquisition, processing, and management of seismic data.  Seismic data management systemic 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 National Petroleum Co-operation (NNPC)

1.2              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 the main by seismic data processing transforms and refines these data to the 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 they cannot manage them effectively.  This has created many problems 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.

1.3              PURPOSE OF THE STUDY

This research will be very useful to both student individuals, co-operate bodies and the general public as a whole who are either engaged or way wish to engage in seismic data acquisition and processing in the future

The purpose is as follows

1                    Ensuring the acquisition of good quality seismic data in an effective manner.

2                    Ensuring that all field tapes collected from the field are sent to the processing center and then its seismic data in tapes are presented in a form that is convenient for geological interpretation.

3                    To ensure that processing sequence are followed and a good result suitable for acceptance.

1.4              OBJECTIVE OF THE STUDY

For fast data processing, you ensure the reliability of data to discover more hydrocarbon.  To increase revenue by engaging in acquisition processing and management.

1.5              SCOPE OF THE STUDY

In this research work, the study was limited to the use of Electronic Data Processing (EDP) on the information management control in the seismic Data processing.

1.7       ASSUMPTION

It is assumed that if this program is properly implemented.  It will go along way to eradicate the challenges and constrength encountered in the existing system.
