Estudo de modelos ARIMA com variáveis angulares para utilização na perfuração de poços petrolíferos.

Abstract

Time series involving angular data appear in many diverse areas of scientific knowledge. For example, in the drilling of a directional oil well, the displacement of the drill, along the path of the well, can be considered as an angular data time series. One of the objectives, in this context, consists in carrying out forecasts of the future positions of the drill, which will give more support to the petroleum engineer in the decision-making of when and how interfere in the path of a well, so that this follows the planned course. In this work, we study some classes of models that can be utilized for the modeling of that kind of series.
