Imaging and monitoring onshore reservoirs or gas storages with reflection seismology is a
challenging task, primarily due to near‐surface noise, scattering, and seasonal changes …

Monitoring the waterflood oil recovery process is a difficult task for seismic-based methods in
hard carbonate reservoirs. The changes in velocity/density due to water-oil substitution are …

ABSTRACT A novel acquisition scheme using distributed acoustic sensing (DAS)
technology, which enables simultaneous near-surface characterization and deep reflection …

Monitoring fluid saturation and reservoir surveillance are essential techniques for effective
reservoir management. As reservoirs age and water sweep advances, it becomes more …

Waterflooding is the primary recovery method used for oil production in Saudi Arabia and is
performed through peripheral injection of treated sea water to maintain pressure at the …

IOR/EOR stimulation is a complex process that requires frequent areal monitoring to
optimize recovery. On-demand seismic surveys are a suitable solution if cost, quality …

A smart distributed acoustic sensing (DAS) uphole system is proposed that utilizes a cost
effective, permanently installed fiber as a seismic sensor embedded in the shallow …

Waterflooding is a common recovery method used in the production of oil from carbonate
reservoirs. Saline water is injected at the periphery of the reservoir to maintain pressure at …

A full-scale 3D surface-to-borehole CSEM survey was carried out to map the position of the
current waterfront around a test well in a producing oil field. Pre-survey modeling studies …

Seismic monitoring of carbonate reservoirs in a desert environment has remained one of the
final time-lapse frontiers due to the low 4D signal produced by carbonates combined with …
