A former technical manager with Petrobras discusses the development of the company’s flow assurance philosophies and strategies. This paper illustrates a numerical approach to estimate the deposition profile of precipitated wax crystals and its effect on flow-related parameters in pipelines. Options for avoiding these issues are also explored. Systematic experimental and modeling approaches to designing a safe operating strategy for a 5-km deepwater-subsea-flowline case study are presented to address unplanned shutdown and restart events for waxy-crude production.
Saudi Aramco studied such algorithms to produce images simulating the flow inside a pipe’s cross section, possibly reducing the need for separator-based multiphase flowmeters. A former technical manager with Petrobras discusses the development of the company’s flow assurance philosophies and strategies. Looped lines are used to reduce pressure drop and increase flow capacity, but information on the flow behavior or predictive methods are not available for these systems. Bypass pigging has advantages over conventional approaches. Its application to multi-phase flow with high wax content crude is discussed.
Petrobras says it can produce oil for a lower break-even price than onshore shale plays, including the Permian Basin. Brazil’s offshore sector has cut the cost of deepwater production but comparisons based on break-even prices are slippery. It's Hard To Make Money in Deepwater, Even With Billions of Barrels To Produce Low oil prices have made the goal of this Petrobras project and its four partners to lower the break-even price of operating to USD 35/bbl.
P-68 is Petrobras’ fourth FPSO to begin operations this year following the startups of P-67 at the Lula field and P-76 and P-77 at the Buzios field. Chinese firms stepped in for the majors in Brazil’s two underwhelming offshore auctions. The round included a near-$1 billion signature bonus on a Campos Basin block awarded to a Total-led consortium. Petrobras and Shell have brought online the Lula field’s seventh FPSO as the firms continue to ramp up production from the pre-salt Santos Basin. The paper provides a fast-track approach to perform screening assessment of multiple subsea concepts.
The Offshore Technology Conference announces the 2020 recipients of the Spotlight on New Technology Award. Eighteen technologies from 14 companies from around the world will be awarded this year, including six companies that will be recognized for the Spotlight on Small Business Award. Amid continued health and travel concerns, the OTC Board of Directors felt this decision was the most feasible and responsible. Petrobras says it can produce oil for a lower break-even price than onshore shale plays, including the Permian Basin. Brazil’s offshore sector has cut the cost of deepwater production but comparisons based on break-even prices are slippery.
