Abstract
Summary Fiber optic cable conveyance by coiled tubing (CT) broadens the opportunity for vertical seismic profiling (VSP) data acquisition during planned CT interventions. This paper presents a case study of an opportunistic CT distributed acoustic sensing (DAS) VSP acquired simultaneously with the distributed temperature sensing (DTS) warmback survey of a recently stimulated unconventional well. The subsequent VSP processing is shown to overcome the significant noise challenges inherent in CT DAS data, such as persistently strong borehole tube waves induced from the surface operations activities. We present the depth tie between surface seismic and CT DAS VSP derived corridor stack images, demonstrating the viability of CT deployed fiber to opportunistically acquire DAS VSP data.
