Reservoir which has been subject to brittle deformation contains fault s with displacements from a few millimeter to tens and hundreds meters, but only part of these faults may be mapped by seismic survey. Despite the complexity of the faults and fault system, two major factors, the resolution of detection tool and the grid density of line search, influence the detectability of a fault . This paper discusses the impact of seismic grid pattern on the unmapped faults and proposes the use of Horvitz-Thampson estimator for estimation of number and sizes of fault unmapped by seismic survey in a region under investigation. Computer generated fault populations in space are then used to illustrate the application of this probability model.
