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.
MWD/LWD refer to measurement and logging while drilling. The MWD operator measures the path of the wellbore while it is being drilled, and this data is then used to help plan the direction that the well will be drilled. LWD, while sometimes used interchangeably with MWD, refers more to the process of obtaining information about the rock being drilled, while MWD is more about the drilling operation.
