... to reduce production deferment and flaring while mitigating the risk of loss of containment during continuous production. The smart plug eliminated the need to depressurize the 100 km GE pipeline (an ~6-8 days activity), which would have resulted in ~30 MMscf/d gas flaring for ~4 days and significantly...

... Operating safely by maintaining the structural integrity of a pipeline is one of the most important objectives in the design of any oil and gas network. A system must be designed by considering a range of operating parameters expected during the design life. Often, deviation of the process...

... (PDG) concept was developed as an inline gas-liquid separator which separate liquids from the gas and flows into a separate liquid line, along with new approaches to flow assurance design, to induce hydraulically ‘dry gas’ behavior within a wet gas pipeline over the operating envelope. The work aims...

... projects, several measures are presented, including the reuse of flexible pipelines from the decommissioning project of FPSO Capixaba (Jubarte Field), which resulted in more than 50 km of lines (36% of the total scope of the project) being used in another project. It also addresses the lessons from...

Despite the significance of these insights, existing models have yet to integrate a coupled advection-diffusion-reaction framework to comprehensively understand barium sulfate scale deposition in pipelines. This study aimed to conduct a comprehensive investigation into the barium...
