Three‐dimensional modelling of magnetotelluric data to image Sehqanat hydrocarbon reservoir in southwestern Iran

Abstract: A detailed magnetotelluric survey was conducted in 2013 in the Sehqanat oil field, southwestern Iran to map the geoelectrical structures of the sedimentary Zagros zone, particularly the boundary between the Gachsaran Formation acting as cap rock and the Asmari Formation as the reservoir. According to the electrical well logs, a large resistivity contrast exists between the two formations. The Gachsaran Formation is formed by tens to hundreds of metres of evaporites and it is highly conductive (ca. 1 Ωm–10 Ωm),… Show more

“…Over the past decades, electrical magnetic (EM) surveys have been developed based on airborne, controlled‐source, or natural‐source methods (e.g., Magnetotellurics (MT) and Audio‐frequency MT (AMT)). They have been valuable tools for studying hydrogeological features such as wetlands (McLachlan et al., 2021), aquifers (Koganti et al., 2020; Korus, 2018), volcanoes and geothermal areas (Árnason et al., 2010), hydrocarbon reservoirs (He et al., 2010; Mansoori et al., 2016), ore deposits (Tuncer et al., 2006), salinity mapping (Cox et al., 2012), and fault systems (Tietze & Ritter, 2013). Generally, the artificial EM surveys are suitable for shallow depths and small areas, while the MT yields general locations of anomalies at depth with little detail.…”
