Abstract:
This paper shows the design process of a directional well, which is based on given coordinates of the target and the cellar that has been selected to drill this well. It will be very much in mind aspects of anti-collision for the section of the indicated cellar, technical security, minimal costs, utilities and environmental safety and carried out the calculations required for the selection of the cellar. The decision on the type of profile is made based on the analysis of correlation of wells, a stick chart showing the collection and management information such as: the location of wells, type of profile of wells, the type of bits, BHA’s, characteristics of the drilling mud, casing types, along with different problems that have occurred in the same operation, which helps us make a better design of the well. Finally, it will be an optimum selection of the number of casings, assemblies used according to the profile of the well, the estimation of the parameters of drilling mud, hydraulic calculus, design of cementing, cost-time estimation and selection of the rig, according to the design required.
