This is a replica of a single link of the anchor chain from the Devils Tower spar. The chains radiate to cover an enormous area of the sea floor, before finally anchoring the rig in place, 5,610 feet below. A single link of anchor chain weighs 545 pounds, and approximately 3,232 links of solid steel chain links hold the spar in place.

The world has produced petroleum for 5,000 years. This timeline illustrates events that were happening in the world as the petroleum industry was exploring, developing and producing the world's petroleum reserves. Today, approximately 65% of the world's energy consumption is supplied by petroleum products.
Today it is estimated that 60% of the world's recoverable petroleum and gas hydrate reserves are located under the oceans. In the United States approximately 70% of our anticipated petroleum reserves are off-shore. Currently, Texas and Louisiana produce 93% of all the USA offshore oil production.
The efforts and investments made by the petroleum industry have provided the energy we require to sustain our way of life.
