Exploration Basis
A series of brief flow tests were conducted on the Phase II reservoir between 1989 and 1990 leading up to the LTFT.
The rate of water loss steadily declined following an initial transient period of increased water storage within the Phase II reservoir. After 9 out of a total of 17 months of pressurization at 15 MPa above hydrostatic pressure, the rate of water loss from the Phase II reservoir approached a constant value of about 0.13 L/s, suggesting a transition to diffusional water loss from the spherical reservoir volume.
