Mud logging technicians in an oil field drilling operation determine positions of hydrocarbons with respect to depth, identify downhole lithology, monitor natural gas entering the drilling mud stream, and draw well logs for use by oil company geologist. Rock cuttings circulated to the surface in drilling mud are sampled and discussed.
From this position they guide the stands of drill pipe, typically 90 feet (27 meters) long, into the fingers at the top of the derrick while tripping (removing the drill string) out of the hole. When tripping into the hole (or "running in") they will pull the pipe out of the fingers and guide it into the elevators suspended from the top drive.
A pumpjack is the overground drive for a reciprocating piston pump in an oil well. [1] It is used to mechanically lift liquid out of the well if there is not enough bottom hole pressure for the liquid to flow all the way to the surface. The arrangement is often used for onshore wells. Pumpjacks are common in oil-rich areas.

The Illinois Basin has produced more than four billion barrels of petroleum. [6] Major oil production began in 1905, and from 1907 through 1912, the basin was the third-most oil productive area in the United States. Oil production peaked in 1908 at 34 million barrels per year, and declined steadily to 5 million barrels in 1933.
Subsalt: Refers to oil prospects that lie below a salt layer. [7] Toolhand: Refers to a third party (down hole services provider) service representative or field service supervisor with "tools" to be run and operated in a well.
