Performance of a Highly Hydrophobic Coating for Solids Management in Production Systems
Recorded On: 06/27/2019
Deposition of inorganic and organic solids in production systems compromises throughput and can cause other operational and safety issues. Once formed, remediation of deposits is costly, often resulting in lost production. Solids management strategies typically involve a combination of chemical injection, thermal management and periodic chemical or mechanical remediation operations specific for each depositing species. Internal coatings offer another potential approach to solids management. In this presentation, we evaluate the performance of a highly hydrophobic diamond like carbon (DLC) coating on deposition of common production system solids. The coating is a 200-nanometer thick functionalized amorphous DLC coating that is molecularly bonded to the substrate through a plasma deposition process. The impact of the coating on deposit formation and adhesion is investigated through use of bench scale, pilot scale and field scale experiments for wax, asphaltene, inorganic scales and hydrates. Based on the positive results of the performance testing, a commercial-scale application facility has been designed, constructed and in commercial operation.

Reservoir Fluids and Flow Assurance Consultant
Dr. Ratulowski received his B.Sc. degree in Chemical Engineering from Purdue University and his PhD also in Chemical Engineering from the University of Houston. He has worked for 16 years in the reservoir and facilities engineering departments of the Bellaire and Westhollow Shell Technology Laboratories in Houston. During this time John was involved in thermal recovery projects, equation of state development, physical property and phase behavior measurement and organic solids measurement and modelling. In 1999, John assumed the role of Vice President – Research for DB Robinson After the acquisition of DBR by Schlumberger in 2001, John acted as Reservoir Fluids Research Director at Schlumberger’s DBR technology center in Edmonton Alberta Canada and Reservoir Geosciences Research Director at Schlumberger Dow Research Center in Cambridge Massachusetts until his retirement in 2017. John is currently an independent consultant in the areas of reservoir fluids and flow assurance.
