“…A more detailed analysis of these options can be found in (Hornman et al, 2015).  DAS 3D VSP with permanently installed fiber-optic cables offers minimally-intrusive, economical and repeatable areal coverage (Mateeva et al, 2013). Since DAS can be acquired simultaneously in many wells, a single pass of shooting on an areal grid can image a substantial portion of a field, overcoming the areal limitation of traditional VSPs.…”

Beyond exploration, the most important role for geophysics in the oil and gas industry is to influence field operations, so that the value of existing assets is fully realized. The recent trend in time-lapse seismic has been toward very frequent reservoir monitoring, with the aspiration to optimize both near-and long-term field management. In this paper we describe steps taken by Shell to tackle the main challenges of frequent seismic monitoring -cost, intrusiveness, and value realization. Offshore, cost reductions can be achieved through novel types of receivers and more efficient vessel utilization. Onshore, cost and footprint reductions are sought through novel survey designs, including fiber-optic DAS cables, sparse geometries, and movable subsurface sources. A demonstration of value is currently pursued through a large onshore trial of continuous monitoring of steam injection at Peace River, Canada, active since 2014. Initial results indicate that steam non-conformance can be diagnosed, remediation actions taken, and their effectiveness evaluated. Inter-disciplinary collaboration is a must. The associated workflow for assimilating frequent seismic data continues to develop and should benefit future monitoring projects both onshore and offshore. Offshore SEG New Orleans Annual Meeting

“…Distributed Acoustic Sensing (DAS) is rapidly gaining popularity in the oil and gas industry especially for Vertical Seismic Profile (VSP) imaging and for reservoir monitoring Cox et al, 2012;Mateeva et al, 2012Mateeva et al, , 2013Daley et al, 2013;Madsen et al, 2013). The advantages of DAS for borehole applications in terms of costs, the deployment mechanism, and spatial resolution make its usage attractive over conventional geophone acquisition (Lumens et al, 2013;Mateeva et al, 2013).…”

Distributed Acoustic Sensing (DAS) deployed in multiple wells was used in Brunei for simultaneous recording of seismic signals emitted by a source grid on the surface. Such a configuration works similar to a 3D Vertical Seismic Profiling (VSP) survey with conventional geophones and provides interval velocities, time-depth relationship as well as images below the wells based on the reflected seismic rays. DAS VSP data has provided the opportunity of impacting asset performance by: (1) improving the image of the legacy 3D surface seismic by remigration using the updated shallow velocity model, thus minimizing both the structural as well as the depth uncertainty, and by (2) providing compelling DAS-only 2D and 3D images beneath the wells with higher resolution than the surface seismic. These can be employed for the reservoir static and dynamic model update and identification of sub-surface seismic faults and/or other events. Additionally, this technology presents the possibility of fluid monitoring in this type of reservoir where production is supported by water injection.
