The infill drilling programme will be carried out within the existing oil-field licence area, which is already operational. The operation was screened B/1, requiring an environmental audit and an environmental analysis, which were carried out by an independent environmental consultant, including a corrosion expert.
The environmental due diligence highlighted the key concerns associated with: corrosion of the pipelines; oil-contaminated land (415 hectares); air emissions; and occupational health and safety concerns arising from the company's activities. No significant issues specifically associated with the infill drilling programme were identified. The due diligence also showed that Chernogorneft has developed an internal environmental management system and is in the process of addressing key issues of concern. The EBRD's funding will accelerate the company's environmental programmes.
The company has established a well-organised and proactive programme for environmental and health and safety management. The company's environmental programme includes aggressive corrosion monitoring and prevention plans and a pipeline replacement programme (over 500 km during the next nine years). The 415 hectares of contaminated land will be cleaned and recultivated over a four-year period, with over 130 hectares and 22 mud pits scheduled for remediation in 1997.
The company separates oil from the associated gas and water in the field, and again before it enters the main Russian pipeline system. It utilises 99 per cent of the gas, and has eliminated flaring, except in the event of an emergency. All of the associated water is re-injected back into the reservoir to maintain the pressure and minimise the impact on the environment. The company has also minimised the area of land needed to be cleared for oil wells. It is using advanced drilling and waste management techniques to reduce or eliminate the need for mud pits. Further environmental improvement plans have been agreed with the environmental authorities.
The progress of the company's environmental programmes will be closely monitored by the EBRD. This will include routine reporting of environmental issues to the Bank and independent environmental audits.
