The effects of vertical flowmeter placement relative to the vertical fracture opening were examined using the colloidal borescope flowmeter (HB). For these measurements, the HB measurement interval was located at a depth equal to 0.5-inch above and below the top and bottom edges of the fracture, respectively; at upper and lower edge of the fracture; at the center of the fracture; and 0.25-inch above and below the center of the fracture. The HB measurement interval was radially centered in the borehole. For those tests, the simulated flow direction was 180, aperture was 1.0-inch and the velocity was held steady at 297 ft/d. This sub-study was intended to identify potential influence of turbulent eddies on measured values and the importance of optimal flowmeter placement. The HH was not used to make measurements for the sub-study because the tool has a larger measurement interval and could not make measurements at depths as precisely as the HB.
