Access to markets is clearly important to us. We believe that pipeline transport is the safest way to move oil and natural gas, but we take a very long-term view and temporary ups and downs in commodity prices don't tend to shape our strategy. We do believe that there is a long-term demand, and there is growth in that demand for oil and natural gas.
We have resources that can be developed so we aim our research efforts at how to develop those more smartly. We're taking a 5, 10, 20-year view in that research.
