Unformatted text preview: Hydrocarbons have seeped up a fault and then evaporated, leaving stained rock in this outcrop on the Santa Barbara Channel, California. The North American pioneer oil well in Titusville, Pennsylvania, drilled in 1859 by Col. Drake A thicket of oil rigs in Long Beach, California in the early part of the 20th Century, before the days of regulation of drilling and pumping activity A rig, drilling for oil or gas Christmas Treesbrightly lit rigsare a common sight in the Texas night time landscape. Nowadays, most drilling occurs offshore in anything from shallow to very deep water. The simplest hydrocarbon molecule is methane, the chief ingredient of natural gas. Methane has a single carbon atom in the chain. Rivers feed sediment into the Gulf of Mexico, which is an example of a sedimentary basin. This false-color image of the Mississippi River delta shows a plume of muddy fresh water being delivered into the Gulf of Mexico. Mixing of the plume with salt water causes the mud to precipitate immediately offshore. In this sandstone, the pore spaces among well-rounded sand grains are filled with oil. Not all of the oil can be extracted by primary recovery; a film clings to each grain. Methods of secondary recovery are devised to obtain some of this remaining oil. A porous sandstone reservoir rock in Mexico was impregnated with epoxy resin. A porous sandstone reservoir rock in Mexico was impregnated with epoxy resin....
