...S.. Trina; T.. Johansen Summary There is a lack of comprehensive simulation tools that (a) accommodate the complexities of advanced completions together with near-wellbore behavior and that (b) have reliable wax-precipitation models for production planning. In this work, these issues are tackled...

... together with near wellbore behaviour, and (b) has reliable wax precipitation models for production planning. In this work, these issues are tackled by combining three specific models. Firstly, a steady-state, three-phase, non-isothermal flow model in advanced horizontal completions was implemented to run...

... that as the apparent molecular weight of crude oil (solution) decreases, its cloud point temperature also decreases. So that, wax precipitation will be delayed. Therefore, microbial biodegradation of heavy paraffinic hydrocarbon components, especially normal alkanes, will be one of the most effective methods...
