... technical and environmental challenges, such as adverse weather conditions and being located in an ecological reserve. Some adverse characteristics were: Viscosities up to 2.000.000cp at environmental temperature (10°C). Pumps installed at different depth conditions. Example, the 2019 NLL-well...

... initially attributed to three distinguished and uncorrelated factors: Premature water production caused by fault reactivation ( Dos Santos 2014 ) and subsequently increases in viscosity of the produced fluid. Productivity index (P. I.) lower than the one established in the project. Emulsion...

... such as xylene to contact the scale, even with the addition of mutual solvents. More recent work with crude oil viscosity reducers has shown that both inorganic and organic scale deposits can be successfully removed by spotting/jetting with coiled tubing without the need of a workover (WO) rig. When a treating...

... in case emulsions developed. Maximum viscosity considered was up to 2 times the oil viscosity at reservoir conditions and simulations showed acceptable pump behavior and production. On the other hand field experience has required simulator adjustments up to 11 times the PVT oil viscosity for water cut...

Previous work Models and grid generation The Navier-Stokes equations coupled with the Continuity equation were solved by means of CFD code. For the stationary flow...

... of the tertiary reservoirs, an artificial lift system it is required, the most used are: gas lift, sucker rod pumping and progressive cavity pumps. The quantity of sucker rod pumping wells represents 52 % of the active wells of the field, which produce oils with viscosities from 100 to 90,000 cP, at a mean well...

... lifting systems, which is presented by the high frictional pressure losses that are handled by the system (subsurface equipment and recollection facilities), which occurs as a result of the high viscosity and / or direct emulsions (water in oil) of the produced fluids (viscosities above 500 cp...

For the specific case of the production of these oils to achieve the goal of making this flow economically viable up to the Surface is normally the bigger risk with their high viscosity being the main risk. In this way the use of the cyclic injection of steam is the improved and most commonly used method...
