Experimental Processing of Dual-well 3D DAS-VSP Simultaneously Acquired with OBS in Deep Water Environment in GOM

Vertical Seismic Profile Complete Session

“…This observation method has higher number of fold which can obtain high resolution reflection wave imaging near the well. Besides, the VSP multi-wave data is a great source for AVO study of reservoir response (Coulombe et al, 1996;Wu et al, 2015). Walkaway VSP in which the receivers are placed just above the reservoir are gaining acceptance as a tool to quantify seismic attributes and calibrate surface seismic data.…”

“…In 2012, BP did its first DAS VSP field trial in onshore Milne Point Field, Alaska, where the DAS data was compared to the geophone data at the same well (Li et al, 2012). The results from the Mars Field trial demonstrated the great potential of DAS VSP over traditional wireline VSP in both image coverage and image quality near/under salt (Wong et al, 2015;Zhan et al, 2015). In 2013, we entered into an agreement with our coowner Shell to use their 3D DAS VSP data acquired in the Shell operated Mars Field in Gulf of Mexico.…”
