... is inaccessible ( e.g ., close to the perforations). The problem of asphaltene precipitation and deposition is a major concern for the operators because of the production loss, the requirement for frequent well shut-ins, and the expensive treatment cost for remediating this problem. Asphaltene deposition...

Conventional treatment of asphaltically unstable crude oil entails dosing an asphaltene inhibitor chemistry through a capillary tube into produced hydrocarbons, which is an effective means of preventing asphaltene precipitation and deposition within production tubing and top-side processing units. Additionally...
