"There is nothing permanent except change" Heraclitus The Greek philosopher said it 2500 years ago. And all the changes since then have proved him right. Consider America's energy situa tion: As petroleum becomes harder to find, we are turning to that old standby-coal. But today Conoco is producing coal with technology that yesterday's miners never dreamed of. For example, working together, our petroleum and coal engineers have developed an underground pipeline system that mixes coal with water and pumps it out of the mine, safer and faster. We're also working on ways to change coal into other useful forms, such as synthetic gas and oil. And since America's need for en ergy will continue to grow, Conoco is active in other fields as well-from producing uranium to developing oil from tar sands. At Conoco, we don't just adapt to change; we help shape it. (conoco) Doing more with energy. To learn more about what we're doing with energy, write Dept.
