... Abstract This paper provides an overview of the main efforts that are being endeavored by Petrobras in order to contribute for developing a Brazilian regulation for use and discharge of drilling fluids and cuttings from offshore oil and gas operation, based on operational safety, well integrity...

...) to model the environmental risk from offshore drill cuttings discharge with several different Group III drilling base fluids, (2) to determine the impact of formation oil on the calculated environmental risk, and (3) to assess the use of modeling to differentiate drilling base fluids. In this project...

... Regulatory constraints governing the discharge of contaminated waste water in offshore operations are increasing across the world. In most regions, contaminant (oil) levels above 30 mg per liter are strictly monitored and regulated to protect our environment. These regulations prohibit...

..., in a larger period of time. At Brazilian maritime zones with higher exploitation and production activities the use of larger vessels, aiming to solve the worst cases, was prioritized. Such vessels are also used to respond the small and medium discharges, which could be solved by less robust vessels. The use...

... offshore discharge of these units into the field rather than discharging at a sheltered location. Introducing the " Dockwise Vanguard", with the offshore discharge studies on-going and the first feedback from the industry regarding dry-transportation led to discussions with FPSO owners and operators to go...
