Future of nonmetallic composite materials in downhole applications

Nonmetallic (NM) compositebased materials offer distinct advantages in overcoming the effects of corrosion, scale, and friction on carbon steel to minimize frequent workovers and extend the life cycle of critical downhole products. However, high initial cost and technicalskills limitations pose challenges to more-widespread development and deployment of these materials downhole, particularly in extendedreach drilling and other challenging wells. The complete paper highlights examples of nonmetallic materials selection and qualification for upstream water-injection and producer and hydrocarbon wells and presents suggestions for future progress. © 2020 Society of Petroleum Engineers.
