" ... What can operators do to try to mitigate the paraffin and pressure issues? Many of them resort to mini-fracs which temporarily exposes virgin rock and increases the effective permeability of the surrounding rock. These mini-fracs enhance production rates for a time, but eventually the frac’d intervals fill with paraffin and actually become flow barriers. Operators will also resort to pouring barrels of harsh, paraffin solvents downhole like xylene, mineral spirits. Some will try paraffin-eating bacteria into their wellbores in an effort to clean them up. The problem with these liquid treatments is that either the liquid drops to the bottom of the well and only treats the bottom-most zone or you have to use enough treatment liquid to create a column of fluid which covers the entire productive interval. The result is either a treatment that is ineffective or cost prohibitive. Hot oiling is another technique that is used to clean these wells but it again doesn’t address the root of the problem which is that the oil is crossing the pressure and temperature threshold required to keep it above its cloud point. What permeability that you have in these wells is of little benefit if the near wellbore is coated in a thick layer of wax with little pressure behind it to push the oil into the wellbore for collection. ...
