... potential can be converted into small and inert solid particles in a subsea cooler downstream of the wellhead. The particles will travel suspended in the bulk flow at ambient seabed temperature towards the host facility without any additional flow assurance measures, like pipeline insulation, heating...

... that is exposed to the larger diameter of 7-in. liner. It is not fully understood whether the slugging is caused by the gap at the lower completion or by sand transportation or both. Dynamic wellbore modelling with sand particle transport is essential to model the abovementioned complex slugging behavior...

Through an extensive laboratory study a simple model 1 , 2 , 3 has been developed for pressure drop calculation in pneumatic conveying based on classical Darcy's equation...

... reduction in the particle size of the weighting agent. With this development, invert emulsion drilling fluids can be designed with reduced viscosity in combination with minimal settling potential of the weighting agent. The paper further explains in detail the first field application of this specially...

...) dispersed in brine. The formation damage along the length of a core was investigated and a number of parameters contributing to permeability decline were evaluated. The results indicate that produced oily water containing oil droplets and solid particles can contribute to the permeability decline observed...

... ABSTRACT Presented are results the of an experimental study of formation permeability damage caused by invasion of the inert and extraneous solids simulated by barite particles. The use of barite facilitated X-ray computer assisted tomography (CAT) analysis of solids in the rock (determination...
