Solving the challenges of extended reach well in Brazil; Vencendo desafios em pocos de grande afastamento

Abstract

With the objective of minimizing costs and allowing oil to be produced from reservoirs near the coast in shallow waters (i.e. less than 3 meters) which make the use of standard marine units impractical, several Extended Reach Wells were drilled from special land based locations in an area with increased environmental awareness (mangroves and 'Salinas'). This was the reality faced in the 'Serra Field' located on the north coast of the state of Rio Grande do Norte (Brasil) and under the management of the Rio Grande do Norte and Ceara Business Unit of PETROBRAS.The ratio between the actual displacement and vertical depth of these wells is approximately 2.7, with actual displacement a bit greater than 2,600 meters, with the idea of reaching displacements exceeding 3,000 meters in the future. In order to drill these wells, special new technologies were adopted; the drilling rig was upgraded, specific software for the development of the project considering both the reservoir and planning of the well, along with the integration and commitment of the Team to follow, execution and that of the service companies resulted in significant improvements in the Drilling Times. Tools adopted in the design of the well, and in the monitoring  More>>

Tools adopted in the design of the well, and in the monitoring of the drilling and completion included Torque and Drag Analysis, Rock Mechanics, Drilling Fluids, Well Trajectory, Anti-Collision, Hydraulics and Wellbore Cleaning. This paper will describe the actions taken, the results, challenges and lessons learned during this Exploration Programme in the Serra Field. (author)}
