The ,well,, drilled by a joint agreement between the Superior ,Oil, Company and Pure ,Oil, Company, was off the coast of Louisiana in Gulf of Mexico waters. Since that time, the coasts of Texas, Louisiana, Mississippi, Alabama, and Florida have become some of the world’s most active areas for the exploration and production of ,oil, and natural gas.

Fluids, from blowdown piping and or discharge lines are usually pumped to a knock-out drum separator, where vapor, ,oil,-water ,separation, and recovery take place. After separating the entrained liquid from the vapor, the stream is fed to the flare unit, where it automatically ignites and burns in the atmosphere.

About 10–40% of injected water is recovered from the system during this process. The fluid returning to the surface is called ,flowback, water (FW).

This is because this is the casing that seals the well so that no fluid can escape back up around the casing, rather than flowing from the relief well into the well that is flowing oil and gas. Since the cement will move more easily thorough a larger passage, than a very narrow one, this gap has to be above a certain minimum size.

If the cross section of the passage between the wells is large compared to the narrowest constriction along the path of the ,oil, leak, the mud should flow into the wild ,well, in larger quantities than the ,oil, and gas that is exiting at the sea floor. This will increase the relative amount of mud to ,oil, in the ,well,, until the ,well, is dominated by mud.

The shallow ,well,, number 1, produces heavier, more viscous ,oil, than number 2 owing to evaporation of the lighter constituents at the outcrop. ,Well, 3 encounters edge water. ,Oil, that has migrated to the surface is lost; however, as it accumulates on the Earths surface, the lighter fractions evaporate leaving a residue of asphaltic-like material.

Natural gas extraction involves ,fracturing, rock formations and uses highly pressurized ,fluids, consisting of water and various chemicals to do so (Hein 2012, p. 1). Natural gas extraction, particularly across the Marcellus Shale region, which includes large portions of New York, Pennsylvania, Ohio, and West Virginia, is expected to expand over the coming years.
