In this paper an efficient parallel algorithm to solve a three‐dimensional problem of subsidence above exploited gas reservoirs is presented. The parallel program is developed on a cluster of workstations. The parallel virtual machine (PVM) system is used to handle communications among networked workstations. The method has advantages such as numbering of the finite element mesh in an arbitrary manner, simple programming organization, smaller core requirements and computation times. An implementation of this parallel method on workstations is discussed, the speed‐up and efficiency of this method being demonstrated by a numerical example. Copyright © 1999 John Wiley & Sons, Ltd.
