摘要： Downhole fluid typing with pulsed neutron logging. A method comprises obtaining gamma count rates at a particular borehole depth; calculating a fluid type indicative response value for the borehole depth; determining at least one fluid type based on the response value for the particular borehole depth; and producing a display of the at least one fluid type corresponding to the borehole depth. A system comprises a downhole tool comprising a neutron source and at least one gamma detector; gamma count rates produced due to gamma arrivals at the gamma detector(s); and a processor coupled to a memory, wherein the memory stores a program that, when executed by the processor, causes the processor to: calculate a fluid type indicative response value for a particular borehole depth based on the gamma count rates; and determine at least one fluid type based on the response value for the particular borehole depth.

摘要： Downhole fluid typing with pulsed neutron logging. A method comprises obtaining at least one capture gamma count rate at a particular borehole depth, calculating a fluid type indicative response value for the borehole depth, and determining at least one fluid type based on the response value. A system comprises a downhole tool, including a neutron source, at least one gamma detector, and a processor coupled to a memory. The memory stores a program that, when executed by the processor, causes the processor to obtain at least one capture gamma count rate for a particular borehole depth. The processor calculates a fluid type indicative response value for the borehole depth and determines at least one fluid type based on the response value.

摘要： An electromagnetic perforation device for well casings includes a coil disposed around a core carried by a mandrel. The device further includes a power supply coupled to a current supply device, which is coupled to said coil. A stabilizing member extends from the mandrel and spaced apart on the mandrel from the coil core. The electromagnetic perforation device may be positioned in a well casing, and the current supply device may rapidly supply a current to the coil to created an electromagnetic field in the coil and simultaneously induces a magnetic field in the well casing. The coil, current, and well casing may be selected such that electromagnetic field and the magnetic field produce repulsive magnetic forces that are sufficient to overcome a yield strength of the well casing and perforate the well casing.
