松川最早的几口威尔斯生产井的供水点压力是根据钻井后立即对威尔斯井进行预热时测得的水位和温度剖面重建的。虽然大多数威尔斯井目前生产干过热蒸汽，但重建的压力表明，生产区的压力梯度是超流体静力学的，与Kakkonda的压力梯度相似，Kakkonda是一个以液体为主的系统。这意味着，目前的生产区的松川水库是诱导产生干过热蒸汽的流体撤出。
Feed-point pressures of some of the earliest production wells in Matsukawa were reconstructed from water levels and temperature profiles measured during warm-up of the wells immediately after drilling. Although most of the wells currently produce dry superheated steam, the reconstructed pressures indicate that the pressure gradient of the production zone was super-hydrostatic and was similar to that of Kakkonda, which is a liquid-dominated system. It implies that the current production zone of the Matsukawa reservoir was induced to produce dry superheated steam by fluid withdrawal.
