Paper Number: BHR-2018-153
... ABSTRACT Wax deposition in the onshore and offshore pipelines is a common occurrence and typically hinders the transportation of oil and gas. Accurate prediction of wax deposition in multiphase flow is of great importance to develop economical prevention/remediation strategies. However...

Paper Number: BHR-2018-169
... ABSTRACT Scaling up of wax deposition rates from small scale laboratory flow loops to field pipelines is generally problematic due to uncertainties in currently available state of the art models. Uncertainties in modeling include the right choice of mass transfer mechanism, the extent of shear...

... temperatures below the wax appearance temperature (WAT) through the use of thick insulation to maintain heat from the reservoir. The most common approach for managing deposited wax is pigging to physically scrape and remove the wax. Due to cost reductions in design or operational challenges (e.g...

... layer flowing at pipe bottom and ii) the deposition of smaller droplets is related to an eddy diffusivity mechanism, while larger droplets deposit by gravitational settling mainly on the pipe bottom. The presence of a thin liquid film all around the pipe wall significantly affects the pressure...

..., deposition, and plugging, knowledge in these areas that have been accumulated over decades of research. While still a work in progress, significant advances have been made in describing the hydrate formation in oil-dominated, water-dominated, and gas-dominated systems. One of the end goals of our effort...
