Spanning Canada and the United States, North America is home to a plethora of major industry players, including Exxon Mobil Corp, the world's second-largest publicly traded company after Royal Dutch Shell. The region's oil and natural gas industry is focused on developing oil sands, deepwater gulf prospects and increasingly profitable shale deposits stretching across the continent. One of the premier sweet spots for deepwater exploration, the Gulf of Mexico is the largest body of water indenting the U.S. continental coastline, and its subsea developments continue to spark both national and international interest.
Coiled tubing is a continuous length of flexible pipe wound on a spool that is straightened prior to pushing into a wellbore. There are a number of well intervention operations that can be achieved via coiled tubing, and it is sometimes used as production tubing in depleted gas wells. It is often more cost and time-effective than having to remove tubing from the well, as coiled tubing can be inserted into the tubing against the pressure of the well. Another advantage versus wirelining, is the ability to pump chemicals through the coil.
