the rig crew
Drilling is usually done by a service company or drilling contractor. The drilling crewis composed of a toolpusher, a driller, a derrickman, a motorman and severalroughnecks and roustabouts.
The toolpusher, the location supervisor for the drilling contractor, is usually a senior, experienced individual who has worked his way up through the ranks of the drilling crew positions. His job is largely administrative, including ensuring that the rig has sufficient materials, spare parts and skilled personnel to continue efficient operations.
The driller is the supervisor of the rig crew. The driller is responsible for the efficient operation of the rigsite as well as the safety of the crew. He typically has many years of rigsite experience and has worked his way up from other jobs. While the driller must know how to perform each of the jobs on the rig, his or her role is to supervise the work and control the major rig systems. The driller operates the pumps, drawworks, and rotary table via the drillers console-a control room of gauges, control levers, rheostats, and other pneumatic, hydraulic and electronic instrumentation. The driller also operates the drawworks brake using a long-handled lever. Hence, the driller is sometimes referred to as the person who is "on the brake.“
The derrickman is in charge of the mud-processing area during periods of circulation. The derrickman also measures mud density. The derrickman reports to the toolpusher, but is instructed in detail by the mud engineer on what to add to the mud, how fast and how much. His other job is to handle pipe in the derrick while pulling out or running into the hole. One of the rig crew members who gets his name from the fact that he works on a platform attached to the derrick or mast, typically 85 ft [26 m] above the rig floor, during trips. In a typical trip out of the hole, the derrickman wears a special safety harness that enables him to lean out from the work platform (called the monkeyboard) to reach the drillpipe in the center of the derrick or mast, throw a line around the pipe and pull it back into its storage location (the fingerboards) until it is time to run the pipe back into the well. In terms of skill, physical exertion and perceived danger, a derrickman has one of the most demanding jobs on the rig crew. Some modern drilling rigs have automated pipe-handling equipment such that the derrickman controls the machinery rather than physically handling the pipe. In an emergency, the derrickman can quickly reach the ground by an escape line often called the Geronimo line.
The motorman is responsible for maintenance of the engines. While all members of the rig crew help with major repairs, the motorman does routine preventive maintenance and minor repairs.
A roughneck is a low-ranking member of the drilling crew. The roughneck usually performs semiskilled and unskilled manual labor that requires continual hard work in difficult conditions for many hours. After roughnecks understand how the rig operates and demonstrates their work ethic, they may be promoted to other positions in the crew.
A roustabout is any unskilled manual laborer on the rigsite. A roustabout may be part of the drilling contractor's employee workforce, or may be on location temporarily for special operations. Roustabouts are commonly hired to do the peripheral tasks, ranging from cleaning up location to cleaning threads to digging trenches to scraping and painting rig components.
The operator is the company that serves as the overall manager and decision-maker of a drilling project. Generally, but not always, the operator will have the largest financial stake in the project. As far as the drilling contractor and service companies are concerned, the designated operator is paying for the entire operation, and the operator is responsible for recouping some of that expense from the partners.
Rotating Equipment
The rotating equipment turns the drilling bit. This equipment consists of the swivel,the kelly, the rotary table, the drill pipe, the drill collars, and the bit. The swivel is attached to the bottom of the traveling block and permits the drill string to rotate. The kelly is a square or hexagonal shaped section of pipe that is attached to the swivel. The kelly fits in a matching slot in the rotary table. As the rotary table turns the kelly is also turned. The movement of the kelly rotates the drill string and the drill bit.
Drilling pipe is round steel tubes about 30 feet long with a diameter of from 4 to 5 inches. The drill collars are used to add weight on the bit. Drill pipe has threaded connections on each end that allow the pipe to be joined together to form longer sections as the hole gets deeper.
The drilling bit is used to create the hole. Drilling bit sizes range from six inches to three feet in diameter. The most common drill bits are roller cone bits and diamond bits. Roller cone bits have three cones containing rows of teeth. The cones rotate on bearings and turn as the drilling bit rotates.
The teeth cut and crush the rock to create the hole. The bit also contains small nozzles that spraydrilling fluids to remove the rock fragments from the bottom of the hole.
Diamond bits have a single fixed head that contains many small diamonds. As the bit turns the diamonds cut the rock. Diamond bits also have nozzles to wash away the broken pieces of rock. Different drilling bits are used depending on the type of rock that is encountered.

OPEC
OPEC and Political Instability - The majority of current oil reserves are controlled by a handful of politically unstable countries, especially those in the international energy oligopoly, OPEC.
OPEC's control over the market allows it to control how much oil enters
the market, and the fact that the majority of OPEC countries constantly
contend with terrorism
adds an added element of unpredictability to the international oil
price mechanism. Oil companies have a major incentive to explore in
order to diversify their reserve holdings and hedge against unforeseen
issues in any one unstable part of the world. Furthermore, there is a
growing focus by governments around the world on achieving energy
independence by helping non-OPEC corporations find new reserves through
investment in new technology. This manifests itself in a number of ways, from tax cuts and subsidies to the loosening of environmental regulations.
oil
Oil exploration represents the very first piece of the long petroleum
value chain that ultimately brings gasoline to the gas station at which
you fill your Ford Explorer. Exploration and production are often
referred to as the "upstream" pieces of the value chain, as compared to
refining, distribution, and marketing, which are typically considered downstream activities.
The process of oil exploration looks a lot like the stylized example
above. A company identifies a potentially attractive area to drill,
either onshore (i.e., on land) or offshore (i.e., in the ocean). This
area could be attractive because its near another major discovery, or
because it used to be an operating well that has now dried up, or
because government has released some data that suggest the presence of
hydrocarbons (i.e., gas and oil).
