(
Society of Exploration Geophysicists
, 2021 , Article)
At the site of a water drainage shaft on the campus of Qatar University that serves as a man-made karst analog, two seismic imaging techniques were adapted to use resonant scattered waves recorded during active-source ...
Comprehensive pore size characterization of Midra shale
(
Elsevier B.V.
, 2021 , Article)
Although the Middle East's carbonate reservoirs were the first and most studied rocks in the world, Middle Eastern shale reservoirs are still poorly understood compared with other unconventional formations in the US. We ...
