Abstract
Much of the hydrocarbon production in Brazil originates from offshore operations in pre-salt fields. The pre-salt fields are located more than 300 km from the coast, in water depths of around 2,000 meters, with reservoirs 7,000 meters from the sea surface. Operating in such conditions presents challenges regarding operational safety and keeping low downtime, guaranteeing a high financial return. A critical decision in developing these fields is choosing the best configuration for their wells, as in addition to the points already highlighted, maintenance in the pre-salt is also expensive. During oil well design, engineers suggest several configurations, leaving the field manager to choose the best options. An oil and gas operator is developing a decision support system to assist managers in this decision. This article deals with a software module — ReliaWell — that aims to calculate indicators of integrity (operations safety) and production equipment reliability (ensuring operation continuity). The article briefly presents the software requirements and the process of surveying the indicators to be considered, discusses the methodology adopted for the simulation models, and shows the system architecture and some screens, especially those for data entry and results output.
