Abstract
Apart from hydrates, asphaltenes, and inorganic minerals, paraffinic waxes are also very important in flow assurance area. Evaluation of wax gel behavior has been important as off-shore oil recovery becomes more popular in oil production. Restart after either planned or emergency shutdown requires pump operation in high pressure since a waxy oil forms troublesome gel. In this paper, vane method is introduced to determine wax gel strength by determining yield stress. Prediction of gel strength are discussed in qualitative and quantitative manners.
Keywords
