Selection of effective solvents against asphalteneresin-paraffin deposition in the Uzen oilfield

Deposition of asphaltenes, resins and paraffins in underground well equipment has always been one of the major challenges in the production of highly paraffinic oil at the Uzen field. This problem still remains extremely urgent, and measures to combat these complications are quite costly.

Paraffin deposition processes in wells and field equipment complicate oil production and lead to oil losses, as well as accidents and equipment downtime. For these reasons, it becomes necessary to conduct a laboratory research on the selection of effective solvents against paraffin deposition and methods for their removal.
