WELL THERMAL INSULATION FOR FORMATION SAMPLING OF VISCOUS FLUIDS

摘要

Evaluating a subterranean formation fluid by lowering a testing tool to a depth in a well bore formed in a subterranean formation, limiting well bore fluid convection near the depth with the testing tool, heating formation fluid in the subterranean formation near the depth, obtaining a sample of the heated formation fluid from the subterranean formation, and evaluating at least a portion of the sample of heated formation fluid obtained from the subterranean formation.
