DESIGN & IMPLEMENTATION OF A COMPUTERIZED INFORMATION MANAGEMENT SYSTEM IN SEISMIC DATA PROCESSING
ABSTRACT
This project work focuses on the computerization of information Management Seismic Data Processing system to increase services and enhancement of Oil producing Industries. The purpose of these study is to ensure good seismic data in effective manner, ensure that all field tapes collected from the field are sent to the processing centre and its seismic data tapes are presented in a form that is convenient for geological interpretation, ensure that processing sequence are followed and a good result suitable for acceptance etc. The problem of this study is how can this information collected from the field be presented and protected from destruction. Tape librarians were introduced to help manage the tapes, but as time goes on, the member of tapes acquired becomes, so large in number that the librarians cannot manage them effectively. The solutions to the problem lie in removing any factor inhibit the ability of the librarian to make the storage and retrieval of the tape easy in the organization.
CHAPTER ONE
1.1 INTRODUCTION
The exploration activities involve the acquisition of data and processing. As the 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 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 over emphasized. In the United State of America and Britain, intensive exploration activities are on for the last two decodes all in 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 discoming of hydrocarbon or better more seismic data processing is a key sequence in search for hydrocation.
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. Infact 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 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 for 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 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 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 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.
1.3 PURPOSE OF THE STUDY
This research will be very useful to both student individuals, co-operate bodies and 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 are 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 centre 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 reliable 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 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 encounted in the existing system.
