Part II

Once oil is found it must be extracted. After the drilling site has been prepared the rig is to be constructed. The rig is known to consist of surface equipment and a derrick which houses drilling tools. The derrick is used to lift sections of pipe which are lowered into the hole made by the drill. To get oil and gas out of the ground is not easy.

Sophisticated techniques and equipment must be used to extract the most out of every oil and gas deposit. Experts consider oil recovery to depend in much on natural pressure. Under natural pressure oil flows freely and it is called the natural flow. It is the most economic period of a well life. If oil wells have too little energy to produce oil efficiently, additional energy must be supplied by pumps or other artificial means.

Crude oil must be transported from the fields where it is produced to the places where it is consumed. Pipelines are likely to be the main means of oil transportation. But tankers, barges, tank trucks, and railroad tank cars are thought to be of no less importance. The latest discoveries of welding methods, construction practices and new materials have extended pipeline transportation into harsh environments and deep waters. All the means of transportation carry oil from wells to storage tanks or directly to refineries. Pipelines also carry petroleum products from refineries to markets. Some of the largest pipelines are to carry more than a million barrels of oil daily.

The basic job of a refinery is to convert petroleum into useful products. As mentioned above, crude oil consists chiefly of hydrocarbons. Refineries are to separate oil into various hydrocarbon groups, or fractions, distillation being the first step of refining. The fractions are then chemically changed and treated with other substances. The refining processes may be classified as separation, conversion and chemical treatment. The latest improvements in refining maybe said to have saved billions ofbarrels of crude.

Distribution and marketing appear to be the final links in the petroleum industry chain that begins hundreds of meters below the ground and ends in your home.

Finding oil and getting its products to market have intrigued us for about 150 years. The search, however, was not always as high-tech as it is now. Our industry began, of course, with Col. Drake and his famous well in 1859. The first wells were drilled near oil seeps because, obviously, oil was there. But after the oil seeps were covered, new methods of finding it had to be found. Some of the early "science" is worth looking at.
