    A horizontal directional drill in operation A structure map generated by contour map software for an 8,500-foot-deep (2,600 m) gas and oil reservoir in the Erath field, Vermilion Parish, Erath, Louisiana. The left-to-right gap, near the top of the contour map indicates a fault line. This fault line is between the blue/green contour lines and ...

    [2] [3] An example is the design of a certain M. Hubby of Maysfield, Texas, consisting of an open hollow cylinder with two blades at the bottom edge. [ 4 ] The first known power earth auger was built in 1943 by John Habluetzel , a farmer in Wamego, Kansas , from parts scavenged from other equipment, including a 7-inch helical blade from a screw ...

  7. Extended reach drilling - Wikipedia

    en.wikipedia.org/wiki/Extended_Reach_Drilling

    Extended Reach Drilling (ERD) is directional drilling of very long non-vertical wells. The aims of ERD are: a) to reach a larger area from one surface drilling location, and b) to keep a well in a reservoir for a longer distance in order to maximize its productivity and drainage capability.

  8. Bottom hole assembly - Wikipedia

    en.wikipedia.org/wiki/Bottom_hole_assembly

    Rotary assemblies [2] are commonly used where formations are predictable and the rig economics are an issue. In such an assembly the weight of the drill collars gives the BHA the tendency to sag or flex to the low side of the hole, collar stiffness length and stabiliser diameter and placement are engineered as a means of controlling the flex of the BHA.
