Abstract
Stationary and trolling methods in measuring flow using flowmeter were adopted to investigate the hydraulic connectivity of fractures and to evaluate the applicability of the measurement methods. Stationary method was useful for identifying the inflow and outflow patterns in the measured section, which enabled us to analyze the hydraulic connectivity of fractures between the wells. Trolling method failed to find the inflow and outflow patterns in the well, but was very effective for locating the conductive fractures. Measuring flow in the borehole by both stationary and trolling methods was found to be very efficient for identifying conductive fractures and their hydraulic connectivity in fractured rock aquifer.
