    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 perforator for perforating a subsurface formation surrounding a well bore to ensure perforation of channels in a cement sheath surrounding a casing pipe cemented in said well bore comprising a series of stacked plates, each plate containing spaced apart co-planar, pie-shaped linear charges and a co-planar, pie-shaped non-charged spacer arranged between each of said linear charges. There are preferably four linear charges and four non-charged spacers forming each plate. The linear charges on each plate are spaced angularly from the linear charges on each other plate so that the linear charges are aimed at different angular portions of the bore hole.

    摘要: A system, method and device may be used to monitor conditions in a borehole. Well tubing and casing act as a conductive pair for delivering power to one or more downhole active sensors. At the surface, power and signal are isolated so that the same conductive pair may act to transmit the sensor signals to the surface. In an embodiment, the sensor signals are RF signals and the surface electronics demodulate the RF signals from the sensor power.

    摘要: A system, method and device for interrogating a downhole environment in a borehole beneath a surface includes a source of electromagnetic energy operable to transmit an electromagnetic signal in the borehole, a sensor module, including a passive resonating circuit including a crystal oscillator having a resonant frequency that varies with changes in the condition in the downhole environment in response to a condition in the downhole environment in the borehole and a detector positionable to receive the reflected modulated electromagnetic signal. In an embodiment, a solids-free dielectric medium is provided within an annular volume in the borehole defined by the casing through which the electromagnetic signal is transmitted.
