摘要

apparatus for evaluating a downhole fluid property, method for evaluating the properties of a downhole fluid, and method for monitoring production wells The present invention relates to a method and apparatus for evaluating a fluid property using a transferable carrier in a well bore, one or more light sources carried by the carrier, one or more light sources comprising at least one quantum cascade laser light source, one fluid sample cell which receives light emitted from one or more light sources, and at least one photodetector that detects light emitted from one or more light sources after light interacts with a fluid in the fluid sample cell.
