Naphthenates

The formation of calcium naphthenate deposits is recognized as a major flow assurance issue in many fields, and will continue to grow in importance as the volume of heavy/high TAN crudes produced increases. The mechanisms and parameters which determine whether these deposits will form under field conditions are still poorly understood, and much effort is being spent on understanding these better.

At Scaled Solutions Ltd, we have designed dynamic naphthenate flow rigs  which have been used to investigate the formation and inhibition of calcium naphthenate deposits in the laboratory under conditions closely resembling those found in the field. These test rigs complement the somewhat limited conventional bottle tests, the results of which often do not represent the operators reality. Our dynamic flow rigs have been validated in field studies and are routinely used to assist in the determination of field treatment designs.

More recently we have expanded our capability in emulsion testing to allow tests to be conducted at 100°C and 100Barg using purpose built emulsion rigs.
In addition to the elevated pressure tests, we are well placed to carry out more standard oil / brine testing as outlined on our Oil and Water Testing page. We can carry out stand alone projects to meet the production issues in specific fields. We also offer the opportunity to develop naphthenate solutions in our R&D capacity in 1:1 projects or multi-sponsored JIPs.
