Protein-based fibrous bridging material and process and system for treating a wellbore

摘要

A bridging material for a well treatment fluid that comprises a protein-based fibrous material and at least one additional material is provided. For example, the protein-based fibrous material can be soy protein fiber (SPF). The additional material is a lost circulation material. A process for treating a wellbore penetrating a subterranean formation with minimal or no loss of treatment fluid into the formation is also provided. A system for drilling a wellbore from the surface into a subterranean formation with minimal or no loss of drilling fluid into the formation is also provided.
