    摘要: A method is disclosed for identifying the source of a transported chemical shipment. The method employs either a chemical element or an organic compound with one or more atoms that are non-radioactive isotopes generally not found in nature. A small quantity of the isotopic compound is introduced into the storage vessel containing the chemical to be transported prior to shipment of the chemical. Upon arrival at its destination point, a sample of the chemical shipment is analyzed. Matching the isotopic compound found in the chemical with the isotopic compound introduced into the storage vessel prior to shipment is indicative that the shipped chemical is identical to the chemical received. Non-radioactive materials may further be employed for detecting the source of a newly introduced contaminant in a water supply. The chemical substance may be a non-radioactive isotope of the chemical shipment being transported.

    摘要: A method and a system for minimizing circulating fluid return losses during drilling of a well bore are disclosed. Circulating fluid, or mud, is heated above conventional temperatures for circulating fluids. The heated circulating fluid then contacts a region of a formation, in which a well bore is to be drilled, maintaining the formation at a relative higher temperature than if no special sources of heat were used to add heat to the circulating fluid. The region, at the relatively higher temperature, has a tendency to expand and to be placed in a relatively higher compressive state as compared to a formation at a lower temperature. Consequently, the use of the heated circulating fluid minimizes fracture initiation and growth and circulation fluid losses into the formation.
