... into the horizontal wellbore, where they settle and accumulate. This paper reports the numerical modeling of gravitational deposition of sand in a horizontal well in such heavy oil reservoirs. The numerical model described in this work examines the transport process mechanistically, based on the conservation...

... Abstract The use of magnetic fluid conditioning (MFC) technology to treat downhole problems with wax deposition in the production of waxy crude oil has sparked considerable controversy. A variety of claims have been made about the success rate of the technology in field applications...

...% H 2 S contains significant dissolved elemental sulphur which precipitates in the formation and wellbore during production. One well was perforated over a limited interval to accelerate sulphur precipitation and deposition in the near wellbore region, thus simulating the long term production...

... Abstract Hot oiling is the most commonly used method for removing paraffin deposits in oilfield operations because of its immediate results and relatively low operation cost. However, hot-oiling may also cause formation damage. This study examines the hot oiling practices on 92 Utikuma Lake...

... transfer ents are coupled to changing physical properties of 57-1 the hot oil/water and changing flow regimes. ('Me Bow regime changes as the annulus fills up.) In addition, heat transfer is initially inhibited by wax deposits, but incream once the wax is removed. The model described in this paper accounts...

...: obtained by conventional solvent or solvent/acid treatments, and hot oiling treatments. eODUMON The deposition of hydrocarbon material occurs in the near wellbore area, formation face and perforations. These deposits can consist of paraffins, asphaltenes, emulsions, oil wet =We or other solids...
