a Recorded data from injection and fall-off tests conducted in the open-hole section between 3198 and 3701.8 m. b Semi-logarithmic plot of the acquired pressure data, converted from bar to meters of water column. A straight line is fitted to the data for the first injection test and the Cooper–Jacob method is applied for estimating the transmissivity. c Transmissivity estimated from the first fall-off using Theis recovery method
