INTRODUCTION:
This is the introductory chapter of the chapter, it briefly explains the brief history, statement of the problem, objective, assumption, scope and limitation of the study, hypothesis and research questions about the subject matter are also discussed under this chapter including other relevant information.
The need for a petrochemical industry in Nigeria was conceived for quite a long time. It was however not until 1978 that the idea of using some refinery by-products as feedstock to produce some petrochemical products was conceptualized.
Due to the capital intensive nature of the petrochemical industry, the Nigeria National Petroleum Corporation (NNPC) adopted a phased approach in the establishment of upstream petrochemical plants. The business mission of the Eleme Petrochemicals Company is to profitably manufacture a range of petrochemical products and to market these products locally and abroad.
Eleme Petrochemical Company Limited (EPCL) plants commercial operations with a total number of 1,376 staff, made up of 138 expatriates technical backup services (TBS) and 1,246 Nigerian staff. The Technical Back-up Services were provided by Foster wheeler management operations Ltd. UK (31). Technimont SPA, Italy (66) and Comerint SPA, Italy (33)
Some Nigeria staff were trained in similar facilities abroad while bulk of the Nigeria operation and maintenance staff were trained at the Petroleum Training Institute (PTI), Warri and at the Kaduna, Warri and Port Harcourt Refineries.
However, in 1999 EPCL started a gradual phase out of the TBD personnel as most Nigerian staff gained adequate experience on the operation and maintenance of the plant.
As 138 expatriates TBS Personnel the cost of about $2million per month was abominable as it had negative impact on the cost of operations and cash flows for the company. Today, the cost stands at about $0.64 million for 43 TBS personnel.
Historically, the Eleme Petrochemical Complex project was started in the project engineering division of the NNPC and Mr. S. A. Kufeji as the general manager, championed by Dr. E. I. Onyia as manager petrochemicals. In 1982m, the petrochemical division of the NNPC was created with Mr. O.O. Lolomari as the general manager, while Dr. E. I. Onyia continued his lead push for the petrochemicals programme. Later that year, NNPC signed the consultancy agreement with foster wheeler International Corporation of Reading, UK following a major reorganization of NNPC in October 1985. Dr. T.M. John was appointed the coordinator of the petrochemical sector. During another restructuring of the NNPC in 1988, Dr. James M. John became the first managing director of EPCL in April 1990, when Dr. T. M. John moved to NNPC Corporation headquarters as the group manager directors of NNPC. It was during chief Oyibo tenure that the foundation stone of the EPCL was laid in December 1991, chief Oyibo move to Lagos to become the first group Executive Director, upstream and gas and later the group managing director of NNPC in 1993. Dr. Edet I. Oahimin – Akhimien took over from Chief Oyibo as the third managing director of EPCL in 1992, and piloted the construction of the complex until August 7, 1995, when he handed over to Dr. Andrew C. Uzoigwe as the managing director who was also the first project coordinator of the project in 1999. Dr. Andrew C. Uzoigwe moved to the corporate headquarters as a group executive director. Exploration and production and handed over to Dr. Dannnar the present managing director of the Eleme Petrochemicals Company limited. The complex is of great strategic importance to the country.
This research work is focused on a critical appraisal of the accounting methods in the petroleum petrochemical industry, with the Eleme Petrochemical Company Limited (EPCL) as a case study. It is directed at analyzing the various methods of accounting system used in the operation of the industry if such methods exist and if it conform with the required and recommended standards by the management and the regulatory bodies.
In Nigeria, the operation of the industry – the petroleum petrochemicals industry is being controlled by the NNPC as such the RPCL is a subsidiary to the corporation. The activities of the industry is divided into the acquisition of mineral interest in properties, exploration development and production of crude and gas. Downstream activities involve transporting referring and marketing of oil, gas and derivation F. O. Agboroh (1999:221).
It involves the cracking of the NNPC/AGIP/PHILIPS Joint venture NGL extracted plant. Located at Obiafu / Obrikron, down into broken down to produce other grades of the various components from further action. The complex is involved in the production of mostly plastic raw material, which may serve as raw material down to produce, their end – use products. The plastic raw material induces the following:
Low density polythene (LDPE), High Density Polythene (HDPE) and Polypropylene (PP). some of their end use application involve; film packaging, processed food packaging, bread wrap, textile products.
Injection Moulding;
squeezable bottle for cosmetics, pharmaceuticals and toiletry products, agricultural construction, green housing for multiple season cropping etc.
Blow Moulding:
Jerry cans, industrial cans, cosmetics and oil containers etc. other include, cups, ropes, yean, prayer mat, film wrapper etc. EPCL commission manual (1999:29).
The project or research work is aimed at researching into how these things are effectively costed from each production process to the other, the method of costing used. How effective it is, how their machine and equipment are valued depreciated. Also, to research in the valuation of these materials (stock).

PETROCHEMICAL OPERATIONS OF PETROCHEMICAL INDUSTRY
Petrochemical operations can be sub divided into feedstock acquisition, feedstock storage processing, packaging finished products storage and sales. Cracking under high temperature or treated with chemical and catalyzed. In the case of Olefin base plant, natural hydrocarbon gas are passed through an olefin plant where ethylene and propylene are produced. Polymerized into poly ethylene and polypropylene into polyethylene and polypropylene refines used for he manufacture of plastics, F. O. Agboroh (1999:351)

1.1 STATEMENT OF THE PROBLEMS
The basic statement of the problem of this research work is to research into and find out or examine whether or not accounting methods exist in the petroleum industries and how well it has been practiced if it exist. To also find out if such conform with the required standard.
