We analyze the electromagnetic fields arising in the vicinity of a vertical steel casing due to
the excitation of a vertical electric field antenna placed in the borehole below the casing …

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 …

A baseline surface-to-borehole CSEM survey was performed in a supergiant oil field in
Saudi Arabia with the objective of monitoring the evolution of the waterfront around a vertical …

ABSTRACT I have developed an approximate inversion scheme for surface-borehole
electromagnetic data. The method aims at reducing the computational burden arising by the …

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 …

The development of surface-hole electromagnetic technologies has gained renewed interest
in recent years. This is motivated by the method's capability to provide the sensitivity of the …

ABSTRACT A surface-to-borehole controlled source electromagnetic (CSEM) survey was
acquired in a research well in the eastern province of Saudi Arabia to monitor waterfront …

Surface to borehole (STB) and borehole to surface (BTS) EM measurements are expected to
provide useful resolution of the oil/water contact at reservoir depth. It has been shown …

With the increasing demands for mineral resources in China, artificial-source
electromagnetic prospecting is playing an increasingly significant role. Consequently …

Reservoir monitoring is illustrated on a Borehole CSEM case study. Ways are examined
how to increase the detection power. The following parameters proved important: grid step …
