Pompresultaten
Water levels were measured in the well and pressures recorded in ameradas at
1608 m depth with a normal reservoir water pressure of 161.9 bar at this
level. A submersible pump was positioned at 200 m KB in the well to carry out
a stepwise pumping test for a total of 50 hours with pressure recovery
registration during an additional 97 hours. A volume of 3253 m³ was pumped and
stored in a specially built reservoir. A stabilised flow rate of 72 m³/h was
established at a pressure 148.7 bar for a pressure drop at the ameradas of
13.2 bar. This equates to a productivity index of 5.4 m³/h/bar. The water
level measured in the well during the pumping stabilised at 190 m KB. The 13.2
bar pressure drop represents a reservoir water column of 124 m indicating that
the equilibrium water column head is at approximately 66 m depth. As the water
column cools, its head will descend. The produced water was reinjected after
proper treatment and an injectivity of about 3.7 m³/h/bar was obtained,
establishing a productivity/injectivity ratio of 1.45.
