Abstract

Time-lapse information can be used for different purposes, depending on whether it spans several years or only a few months between snapshots, or even reflects producton/injection-induced seismicity in real time. Synchronizing the availability of such 4D data with production-relevant decision gates, and ensuring sufficient resolution for these decisions, is the key to improve efficiency and optimize impact of 4D. PRM systems need to reliably function over the entire production lifetime of an asset and provide the sensitivity to both detect small 4D signals over short repeat intervals and continuously monitor tiny production-induced deformations. A fiberoptic solution is best capable of providing the required endurance in the seafloor environment over the entire asset lifetime. We present the next generation Optoseis pressure-balanced technology, and some novel procesing techniques that are very useful for PRM with sparse receiver sampling.
