PLATAFORMA ROBÓTICA PARA OPERAÇÕES RIGLESS EM POÇOS P&A

Abstract
The well´s integrity assessment provides important information for planning well´s abandonment, minimizing the costs of rig interventions. More accurate information about the status of the mechanical integrity of the production column, cladding and, cementation can reduce the uncertainty of planning the well´s abandonment operation, which results in time and resources savings in an operation that is sensitive to costs as P&A. However, the operational costs and the logistics required for the data acquisition by conventional well´s intervention end up making its realization unfeasible. In practice, wells´ abandonment (or interventions in general) ends up being planned according to the project data, interventions references that had been carrying out throughout well´s life and some inferences based on the intervention or abandonment designer experience.Performing these operations by an autonomous robot can eliminate the costs of cable profiling or flexitube units, cranes and, operation teams, in addition to enabling the execution of works without the rig need.This paper presents the development of a modular robotic platform to perform through tubing tasks without using wireline, coil tubing or slickline and, also the project´s phases, results of simulations, performed tests and, applications.
