Abstract

Drilling a well is a cost intangible, because a well costs millions of dollars, so the more dollars that is spent in a well, the more oil and gas has to be produced over the life of a well. If costs are not accurate, the economics change after a well has been drilled, as a result, the estimated costs are risked i.e. a success factor is placed on the well. The lower the factor, the lower the chance of success and an estimated cost can change the risk profit of any well. These days the improvement of drilling technology is so challenging, however most of the wells drilled in around the world directional wells are. For effortlessness, a directional well is one that is not vertically drilled purposefully or inadvertently. As drilling activity expands more and more places are becoming inaccessible hence the need for directional drilling. It is essential to comprehend the requirement for directional wells, as well as planning and execution. The idea of directional drilling has changed the way wherein wells are drilled everywhere today, from simple deviated wells to horizontals and multilateral wells; the wells made an unavailable areas accessible while increasing the area for drainage by each well drilled, with the wide application of such methods in the world. This paper represents an overview for directional wells with emphasis of the application using real field data, a case study from Poland related to J-shape, S-shape drilling profile.Moreover,
