SINGLE EQUATION SIMPLIFIES HORIZONTAL, DIRECTIONAL DRILLING PLANS
Michael L. Wiggins University of Oklahoma Norman, Okla. Jonggeun Choe, Hans C. Juvkam-Wold Texas A&M University College Station, Tex. The development of a single equation has simplified the planning of a two-dimensional well bore trajectory. The basic relationship can be modified easily for the various types of directional and horizontal wells. The particular geometry of each type of well bore defines the variables used in the equation.
