2010 EHS performance
Our business has changed dramatically in recent years. We have reorganised our portfolio, invested heavily in Africa and sold our UK gas terminal facilities. We have had a significant increase in activity levels and our production profile is set to grow rapidly from 2011 onwards with the achievement of First Oil in Ghana in late-2010. Both the expansion and changing nature of our activities means that it is hard to set meaningful emissions baseline data for comparison and reduction targets at this time.
We currently monitor our environmental performance in terms of atmospheric emissions, water usage and spills. We assure the Group-level performance data through Deloitte and report annually in this report and online.
In 2010, a detailed review of environmental reporting showed that there were gaps and inconsistency in data collection at an operational level. This means we have restated 2009 CH4 emissions using an updated conversion factor. In addition, water usage was not reported for our UK and Bangladesh activities in 2009, but data for 2010 have been included this year.
We have now documented and adopted industry recognised standards for environmental performance reporting. This system is in place for 2011 with data collection on a quarterly basis. It includes standardised reporting by Ghana, Uganda, Kenya, UK, Bangladesh and Pakistan.
In 2011, we are reviewing in-country waste management requirements and reporting. Waste management is a challenging issue for us in the context of operating in remote sites in isolated parts of the world, with no real infrastructure for disposing of hazardous and non-hazardous waste.
CO2 emissions (tonnes)
Production emissions
Drilling emissions
Well test emissions
CO2 emissions increased by 207% in 2010 primarily due to the FPSO start-up and commissioning process in Ghana.
CH4 emissions (tonnes)
- Production emissions
- Drilling emissions
- Well test emissions
CH4 emissions increased from 24 tonnes in 2009 to 1,395 tonnes in 2010. This increase also mainly relates to the FPSO start-up and commissioning process in Ghana.
Our understanding of water resources continues to mature. To date we have focused on other key environmental issues for our business. With the increase in our activity in Uganda and our entry into drier countries such as Kenya and Ethiopia, water resource efficiency is becoming more material for us. In 2011, we have plans to improve our monitoring and measurement of water use. Until we have established a solid database of our water management, particularly in our operations in East Africa, we will be unable to respond to Carbon Disclosure Project: Water Disclosure, which was introduced in 2009.
Water usage (m3)
Water usage increased to 107,423 m3 for all operated sites compared with 71,683 m3 in 2009. Water usage in the UK and Bangladesh was not reported in 2009 and this accounts for approximately one-third of the increase. The remainder relates to the start-up and commissioning of the FPSO in Ghana.
We had four oil and chemical spills in 2010 (2009: five). Five tonnes was spilled compared with 0.94 tonnes in 2009.
- In Uganda, approximately one tonne of drilling waste was spilt, but 92% was subsequently recovered;
- In Ghana, two spills occurred totalling approximately four tonnes. An hydraulic hose failed releasing 0.1 tonnes of fluid, 60% of which was recovered. The balance relates to oily droplets from flaring which were treated using dispersants rather than recovered. Minimal environmental damage occurred due to the small relative volume of the spill.
- In Bangladesh an unquantified spill occurred in black and grey water onsite. A full clean-up and reinstatement operation has been completed.

Disciplined in deepwater
We are a deepwater operator and being disciplined in deepwater activities has been identified as one of the most important issues for the industry this year.
