New pump engine saves dollars

摘要

Use a sucker rod pump that runs on water. Oil prices have climbed rapidly, but along with them, the cost of power to run sucker rod pumps has climbed, unless an operator can use field fuel. A new pumping system offers a way for some operators to take a bite out of those high costs. The Deluge Inc. Natural Energy Engine grew out of a project in Saudi Arabia dealing with the expansion and contraction of liquid gases. Brian Hageman, founder of the company, describes himself as an inventor. He found that CO{sub}2, stored under enough pressure to keep it liquid, can expand up to 50% with increased temperature, compared with 1% to 2% for water or oil.
