Corporate Responsibility

Throughout the lifecycle of our projects and operations, we continuously evaluate and maintain management of our environmental impact and any related impact on local communities. At a corporate level, we annually review our management of environmental issues such as greenhouse gas emissions, water, and soil contamination. We seek to identify emerging risks and assess methods to reduce them throughout the entire company.

Our operating management system provides continuous improvement for environmental and social performance throughout our corporate-wide framework for a rigorous approach to safety, risk management and operational integrity. It integrates requirements of environmental and social responsibility, as well safety and security, into our daily operations.

Cleaner Drilling Techniques

As of 2007, recent advances in the technology of horizontal drilling have opened up the potential of enhancing and/or revitalizing exisiting oil and gas wells that are exhibiting marginal production rates. Horizontal drilling has changed the way oil and gas drilling is done by allowing producers to drill horizontally beneath neighborhoods, schools and airports. The new technology is significantly cleaner and less environmentally intrusive. For instance, one well bore can now become ten well bores drilled in a "wheel and spoke" fashion over a 5 mile radius.

In addition to extended reach, horizontal drilling may increase production. In "tight" rock (low permeability) geological formation, oil uses fractures to move out of the rock and into the wellbore. The fractures may be natural or induced. A horizontal well exposes more rock (and therefore more fractures) to the wellbore because it is usually designed with the horizontal portion of the well in the productive formation.



On-Site Responsibility

Operation Supervisors set environmental goles and targets on a local level, based on an assessment of their most significant environmental aspects. Annual plans are developed to meet these targets, and corporate management teams are responsible for reviewing progress annually with local management.

These targets can include measures such as flaring reduction, pollution prevention, or reducing impact on land owner property. Impacts on the environment vary from site to site, and according to the nature of each operation. We consider environmental sensitivities in determining which issues require the greatest focus for impact reduction.
