Ocean Star Drilling Museum, Galveston, Texas

The Ocean Star Offshore Drilling Rig and Museum. The retired jackup drilling rig has a video about the offshore industry and features three floors of models and interactive displays illustrating the story of offshore oil and gas from seismic technology to exploration platforms, actual drill bits and remotely operated vehicles (ROV) as well as videos and exhibits explain drilling, geology, seismic, well servicing and production.

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. 

An Oil Rig

Off to work

Top Drive
This device provides improved safety and increased efficiency and represents new technology for rotary drilling. Equipped with powerful electric motors for rotating the drill string, the top drive replaces the kelly and swivel. The top drive hangs in the derrick, attached to the drill string below the traveling block. This type of drilling system is typical on all modern drilling rigs and works with automated pipe racking systems and dual activity derricks.

Drill Pipe
 On a working rig, the area you are currently standing would typically be used  to store the pipe for the drilling of the well. Each piece of pipe is 30 feet long and is lifted one joint at a time to the drill floor for drill string assembly. Three or four joints of drill pipe are screwed together to form a "stand" that is attached to the top of the drill string and lowered into the borehole. 

The Traveling Block is essentially a large block and tackle assembly which is connected to the wire drilling line, often lifting more than one million pounds.

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.
