Reservoir simulation studies: Wairakei Geothermal Field, New Zealand. Final report

Subsidence due to geothermal fluid withdrawal

“…Based on their simulations they conclude that the subsidence bowl lies close to the margin of the geothermal field and that local phenomena such as a seismic slippage along preexisting faults control the offset location of the s~bsidence bowl from the main production area. Based on available data and parametric studies, Pritchett et al (1980) feel that pore collapse cannot adequately explain the peculiarities of Wairakei subsidence. Narasimhan and Goyal (1979) contraction.…”

A history of numerical modelling of the Wairakei geothermal field

“…Pritchett et al (1978) carried out a review of the field data and set up two models of the field (Pritchett et al, 1976(Pritchett et al, , 1980. The first was a 1D vertical column, similar conceptually to the slow drainage lumped-parameter model used by .…”

Because of the availability of data, several authors used Wairakei as a test case for their simulators Pritchett et al, 1976Pritchett et al, , 1978Pritchett et al, , 1980Mercer and Faust, 1979b). Some of these studies have been reviewed by O'Sullivan (1985) and are further discussed in Section 3.…”
