It’s no secret that the oil and gas industry employs thousands of workers across the country in many different positions. According to the Bureau of Labor Statistics, more than 215,000 workers are employed in this field as of November 2014. These workers perform a wide variety of tasks, from manual labor to scientific research. Many of these job titles may not be commonly known to the public, including one of the most important positions: those who control the path of the drilling process.

When a reserve of oil is located and is going to be opened for drilling, the prospective drilling company will use advanced technology to take an accurate survey of where the well is located underground, and the best path to get a bore into it. When drilling a well to access an oil reserve, workers use constantly updated information to ensure that the hole is drilled in the pre-determined, most efficient path and follow the designated plan. This process of guiding the wellbore is known as Measurement While Drilling (MWD) or Logging While Drilling (LWD). The Operators for these tasks, commonly referred to as MWDs or LWDs, are responsible for using the complex technology which provides a second-by-second feed on the progress of the bore.

Specific Daily Activities Performed by MWD and LWD workers include:

  • Interpret drilling data and provide it to the client
  • Manage the MWD equipment, and arrange for transport when necessary
  • Use wireline instruments and advanced techniques to take measurements without disturbing the wellbore
  • Maintain records of drilling progress and other work
  • Evaluate the current drilling process and recommend improvements as needed
  • Develop and maintain drilling plan, ensuring the most efficient drilling path

Directional drillers (DD) perform similar activities, but they are solely responsible for drilling no-vertical wells, also known as slant drilling. In the oil and gas industry, this can fall into one of several categories: oilfield directional drilling, utility installation drilling (horizontal), directional boring, and surface in seam (SIS), which creates a horizontal well to intersect with a vertical one and extract coal bed methane.

MWDs and DDs have made it possible to reach deeper, and more difficult wells, giving the oil industry access to reserves that would have been out of reach without the technology that has developed, and the engineers who are so effective at utilizing them.
