INTRODUCTION

Many oil production processes present a significant challenge to oil and water treating equipment design and operations. The nature of crude oil emulsions changes continuously as the producing field depletes and conditions change with time. This creates the need to consider future performance when designing treatment systems and requires an understanding of scale and up scaling. The programme explores all the theories and technology required in crude oil and water treatment, starting with the emulsion theory formation, stabilization and the mechanism and technology to destabilize and separate water from oil.

After the oil has been dehydrated some oil will still not meet contract specifications due to the amount of salt present in the crude oil. For this reason the programme also discusses desalting technologies and processes needed to achieve the required oil specifications.

Due to environmental regulations and water injection specifications, produced water must also be processed. The programme also provides a summary of the technologies, processes, and operational conditions needed to achieve the specifications for the produced water.

WHO SHOULD ATTEND?

This programme is aimed at technical personnel at grade level within exploration, production, refining and service companies such as:

·         Surface Facilities Operation Engineers

·         Flow Assurance Engineers

·         Production Engineering Staff

·         Production chemists

·         Operations Personnel

PROGRAMME OBJECTIVES

The aim of this programme is to establish an understanding of the processes, technology, equipment, techniques and HSE relating to the Crude Oil and Water Treatment Facilities associated with the production and operation of crude oil at the processing locations. After attending the programme the participants will:

·         Have an understanding of the facilities required for crude oil and produced water treating and processing

·         Understand the principles for the separation of oil, gas and water

·         Be aware of the Oil treatment basics regarding dehydration and desalting of crude oil

·         Be familiar with the produced water technologies employed in the oil industry

TRAINING METHODOLOGY

"Crude Oil Production and Wellhead Process” is a hands on, stimulating learning experience. The programme will be highly interactive, with opportunities to advance your opinions and ideas. Participation is encouraged in a supportive environment. To ensure the concepts introduced during the programme are understood, they will be reinforced through a mix of learning methods, including lecture style presentation, and open discussion.

PROGRAMME SUMMARY
