Solvent systems are used for many oilfield applications. In stimulation, solvents are primarily used to remove heavy hydrocarbon compounds and asphaltenes, prevent emulsions, and to restore wettability of rock surfaces. Each of which can restrict flow in the tubing and near wellbore, require excessive production chemical treatment or cause catastrophic production facility upsets. Operators have found that managing wettability reversal, waxes and asphaltenes with smaller targeted solvent systems has proven to be far more cost effective than shutting in production for extended periods of time in an attempt to overhaul extremely damaged wellbores.
PIC scientists use case specific data to design a solvent system to remedy the specific damage mechanisms present. The fact that the solvent system is customizable means that the properties and components of the system can vary drastically. The systems can range from aliphatic to olefinic to aromatic, from light carbon to heavy carbon number, and contain an array of different additives targeting the specific hydrocarbon range observed.
