DIRECTIONAL Drilling

Horizontal and Directional Drilling vs. Conventional Drilling

Horizontal drilling involves drilling a lateral horizontally off of the vertical wellbore. Directional drilling is the controlled drilling of a wellbore to a prescribed bottom hole location. Both horizontal and directional drilling require the use of downhole mud motors (powered hydraulically by drilling fluid to allow for rotation of the drill bit with little or no rotation of the drill string) to alter the course of a wellbore to hit a specified drilling target. Horizontal and directional drilling operations require two distinct systems to steer the drill bit below the earth's surface to a predetermined target: a positive-displacement downhole mud motor and measurement while drilling ("MWD") technology.

Horizontal and Directional Drilling

When drilling a vertical well, the wellbore is drilled straight down until the oil or natural gas reservoir is reached. Vertical drilling is most efficient when reservoir pressure is high and the formation has high permeability. Conventional drilling is not always the most economic approach given factors such as restricted surface access, geology, reservoir pressure and present value considerations. Horizontal and directional drilling does not compete with or take the place of conventional vertical drilling rig operations. By virtue of the increased productivity and economics associated with horizontal and directional drilling techniques, conventional drill rig utilization levels are actually enhanced.

Benefits of Horizontal and Directional Drilling

  • Improved access:
    The use of horizontal and directional drilling equipment allows for access to previously unattainable bottom hole targets. In addition, horizontal and directional drilling is used when the specific subsurface target is not accessible using conventional vertical drilling practices; for example, when the desired target zone is located directly beneath an extremely complex surface obstacle, such as a mountain, lake, town or environmentally sensitive area.
  • Increased economic performance:
    Horizontal and directional drilling results in a significant advantage over conventional drilling in environments with low permeability or in situations where producers want to accelerate production from a reservoir. In both cases, increased production is achieved through the increased exposure of the reserves to the producing wellbore. As a result, a well’s net present value is increased due to the more efficient production of available reserves.
