“…The Bahrah Field, in northern Kuwait, sits on the Arabian Plate's middle eastern boundary. The tectonic history of the Arabian Plate has been complicated, with eustatic sea-level variations playing a prominent role (Carman 1996;Aladwani 2022b). The plate boundary and shelf edge were 500 km northeast of Bahrah Field during the mid-Cretaceous.…”

“…Apparently, there was some movement in the Albian Age, most likely during the deposition of the Middle Burgan Formation and subsequently during the Late Cretaceous, when the Burgan Arch underwent considerable tectonic expansion. Regionally, the Bahrah anticline feature is considered the northern extension of the Greater Burgan high ridge (Aladwani 2022b;Al-Sulaimi and Al-Ruwaih 2004) and trends north-south direction. However, a significant shear zone to the south of the Bahrah structure separates it from the main Burgan trend leading to a northwest-southeast tendency of the Bahrah structure.…”

We used wireline logs, seismic, core data, fluid analysis, and geochemical data to investigate the total petroleum system in the Cretaceous period. Also, we used thin sections and fluid analysis throughout the investigation. Python’s 1-D backstripping technique was used to determine the abrupt changes in subsidence rates and their effect on the reservoir’s quality. The results defined that the potential reservoirs include, from top to bottom, Mauddud, Upper Burgan, Lower Zubair, and Ratawi Limestone. The reservoir facies reflect different environments between the carbonate ramp (Mauddud, Ratawi Limestone, and Minagish reservoirs), delta plain (Zubair reservoir), and margin shelf (Burgan reservoir), and its quality is graded from Mauddud to Ratawi Limestone from top to bottom. The field lies up-dip under Kuwait Bay and represents the continuation of super-giant Greater Burgan Field. It filled with the spilled oil from the down-dip Raudhatain and Sabriyah fields through a structural saddle. Two major tectonic events subsided the deposited sediments by 0.25 mm/year, besides three minor events; however, these events did not affect all Cretaceous reservoirs but only according to their deposition times. Furthermore, according to burial history, thermal maturity, and reservoirs’ fluid geochemical analysis, the Sulaiy (Makhoul) and Minagish formations are likely the primary sources for all Cretaceous reservoirs.

“…Several authors (Sheng & Callegari, 1984; Salem, 2001; Hacikoylu et al., 2006) used well‐logging data to investigate the joint elastic and electrical properties of reservoir rocks. Others used electrical well‐logging data for hydrocarbon exploration (Aladwani, 2021, 2022a, 2022b; Aladwani et al.,2023). However, well‐log results must be interpreted with caution because of spatial averaging effects for different rock properties and unknown parameters, compared with data collected on small rock samples in the laboratory where rock parameters can be better constrained.…”

We investigated the effect of shale distribution on the joint elastic wave and electrical properties of shaly reservoir sandstones using a dataset of laboratory measurements on 75 brine‐saturated (35 g/L salinity) rock samples (63 samples from the literature, 12 newly measured samples). All the data were collected using the ultrasonic (700 kHz) pulse‐echo measurement technique for P‐ and S‐wave velocities (Vp, Vs), attenuations (Qp−1, Qs−1), and a four‐electrode method for resistivity under elevated hydrostatic confining pressures between 10 and 50 MPa (pore fluid pressure 5 MPa). The distribution of volumetric shale content was classified by comparing the calculated dry P‐wave modulus to the modified Upper Hashin–Shtrikman bound for quartz and air mixtures, assuming pore‐filling shale. This scheme in particular allowed us to distinguish between pore‐filling and load‐bearing shale distributions according to idealized definitions, which provides new insight into the joint ultrasonic properties and resistivity behaviour for shaly sandstones. In resistivity–velocity space, the resistivity of load‐bearing shale increases with increasing velocity which form a more distinct trend with steeper gradient compared to those for partial pore‐filling shale and clean sandstones. Moreover, the pore‐filling shale trend straddles the clean sandstone trend and meets the load‐bearing shale trend between 100 and 150 apparent formation factors. In resistivity–attenuation space, the highest attenuations exist when the volumetric shale content is close to the frame porosity (for Qp−1 in particular), at the transition between pore‐filling and load‐bearing shales. The results will inform the development of improved rock physics models to aid reservoir characterization from geophysical remote sensing, particularly for joint seismic and controlled source electromagnetic surveys.
