Cost-effective flow assurance in subsea, deepwater, and unconventional applications.
Where hydrocarbons depressurize and cool, paraffins can nucleate and grow into crystal structures that can impact production through gelation, higher pour point and viscosity, and deposition. Operational issues such as reduced flow, increased backpressure, and waxy sludge formation in storage tanks can occur.
Our proven approach starts with gathering and examining field information, followed by designing and implementing laboratory tests to determine the optimal treatment.
Our range includes
If the optimal product is not part of our existing range, we can design a product specifically for your application.
Ambient conditions during treatment application are considered when selecting and designing the most cost-effective solution. For example, stability under extreme conditions, such as deepwater environments, is assessed when appropriate. A full range of deepwater-stable, umbilical-safe products is available.
We also provide a range of paraffin dissolvers to remediate deposition and restore production to optimal levels.
Schlumberger uses mechanical, thermal, and chemical techniques to treat deposited waxes.
Chemical dissolution treatment necessitates application of solvents that will effectively and efficiently remove paraffin wax deposits, dissolving the paraffin regardless of structure, size, or melting point. This process requires much less energy compared with melting the wax crystals. Solvent effectiveness improves with increased temperature and agitation.
Available solvents include chemistry based on aliphatics, aromatics, esters, terpenes, and more. The most effective product that meets the application requirements can be selected or designed based on your preferred parameters to ensure that your performance, cost, and environmental goals are achieved.
Prevent and inhibit issues such as scale, deposit formation, and corrosion.
Dissolved solids components of crude oils affect a wide variety of applications.
