Use of interferometric techniques for detecting subsidence in the oil fields of Kuwait using Synthetic Aperture Radar Data

Subsidence in Burgan oil field of Kuwait has been studied by Interferometric technique using Synthetic Aperture Radar data. Repeat pass Interferometry is applied to the study area that accounts for infinitesimal changes in the topographic elevations. Subsidence of about 27 mm over a period of 3 years was estimated in Burgan oil field area. The study is significant since continued subsidence may result in reduction of porosity of host formation and may activate the sub-surface geological structures, which can compromise the integrity of the reservoir seal, leading to migration of hydrocarbons to other formations and areas.
